Could this mix be bug-out bag material? What’s the expiring date of that AG1 stuff?
Is that number in milli or microrem?
Whats up my rad equevelent men(dudes)? What kind of meds did Brian had for his covido treatmento?
Really really refreshing to see a scientist saying things things like 'I don't know' and 'I haven't done the research'. And this is coming from a guy who studied chemistry and talked with scientists on the regular. You don't see it in the wild very often.
It's much more common that they either get really defensive about it or make something up on the spot.
That's why I don't quite understand the almost unquestioning faith some people have when a man in a white coat or with a "Dr." in front of their name tells them something. Doesn't matter how ridiculous it sounds, doesn't matter if it's later proven to be wrong or even an outright lie, people will just go right on taking their word for it.
"Well he/she is a scientist so they know better!" No, they just have more education on a given subject, at the end of the day they're still human and humans make mistakes/behave selfishly.
NOT A CHEMIST!
"I don't know _______, I think it is __________, but I can't say for certain."
It is a great phrase, you get there inferences if someone with knowledge and experience, but also the knowledge to look into it further, maybe with an idea if what to look for.
Most of the scientists I know are pretty good about knowing the levels of their knowledge.
It's fun to see Brian and Jason freak out but it's hilarious when it's over radiation.
Yeah, watching them flip out over something minor as Uranium Glass is hilarious. If Uranium Glass really posed a health hazard, the folks over at the Atomic Energy Commission would be all on that like flies on shit.
One of the most interesting things about radiation from my perspective as a Geology enthusiast is how much the Earth is actually heated by the radioactive material inside of it. Radiation along with primordial heat left over from the formation of the planet are the most significant sources of heat inside of our planet.
isn't it mostly mantle convection?
@@1224chrisng That would be one of the processes that bring heat from inside the planet up to the surface. However, the source of that heat mainly comes from radioactive decay and the heat left over from the formation of the planet. Sources online say that about half of the total flow of heat to the surface is made up of radiogenic heat, i.e. heat produced from radioactive decay
so, if the sun went out, how much of the earths surface would freeze, and how deep would it go until it wasnt able to overcome the internal heat?
@@frigglebiscuit7484 From what I understand, the Sun accounts for the overwhelming majority of the heat that we experience on the surface, but provides very little energy to the inside of the planet. While I'm no geologist (yet🤞) my best guess would be that the Sun disappearing wouldn't affect the inside of the Earth too much. I imagine it would stay tectonically active for quite a long time still.
@@frigglebiscuit7484 Atmosphere would freeze, a layer of ice would form on the ocean (but full ocean freezing would take hundreds of thousands of years.) Heating from the Earth becomes more important than solar heating only a relatively short distance into the ground, so the vast majority of the planet's volume would remain hot without noticing the sun was even there at all. It depends exactly where you are but in most places the internal heating becomes more important after only a few hundred meters.
You guys found a great PhD. A lot of academics have zero stage presence or are overconfident and think they are an expert in everything. Jim clearly knew his shit but was also cheerful and worked well with you guys. And of course your performances made this all better.
this was very interesting, no flashy youtuber guest, just a... scientist
he explains very clearly,knows his stuff and best of all got pissed off at your legend testers bit
you should get more real scientists on the show, they are always fun
and no, corey doesn't count as a scientist
Does he count as an engineer?
I would love to see this raw video. There were several cuts where some very boring and not CZcams worthy stuff likely happened. I'm just saying
@@Reddotzebra An engineer of dreams maybe, not the "I'd let him work on my house" kind
@@jman1121 That's what you get with Patreon support.
I love how he apologizes by saying 'not trying to science talk' with a smile on his face and clarifies he is just trying to be precise.
I have been told more than a handful of times that I'm being too precise or technical. But precision does matter at times. Lol
I love this episode, the rogues delving into heavy science.
Would definitely be interested in seeing your guest again. And or something in the same vein with a scientist in another field.
This was a super fun episode! Jim didn't take himself too seriously, plenty of humor, 10/10 would watch more episodes with him
Jim is such a fun guy. I’d watch a whole show of him teaching science
The named, special taco that gets sold out of the Radioactive Taco Truck should be called the "Generally Accepted as Safe".
I won't partake of anything ranked that low, I need Admirally accepted or better.
@@RovingJackyou win today
I haven't watched the episode yet, but I really hope Jason has super powers now
He probably already does they're just really crappy powers like the ability to block knives thrown at _exactly_ 37 meters per second with his eyeball, but JUST the eyeball, nothing else.
Reset the mutation counter
This is not necessarily the case if you get hit with ionizing radiation (since if you get unlucky it can and will smash both strands at once) but, the actual reason our DNA is double stranded, that it's a double helix like everyone knows, is that the strands are each other's mirror image. So if you have a bit of one strand and the other is smashed up by any kind of incoming damage, it can repair itself by using the other strand as a guide. (Not really "by itself", it still requires raw materials and a few proteins to do this.)
There is a lot of fear and lack of understanding when it comes to radiation. Thank you for making a video that helps address the topic.
When the radiation scientist starts saying" now that's a really good question" you might wanna take heed 😆
Well, he's a scientest, not an electronics engineer. Guy probably doesn't really know all that much about the practical side of wear and tear on CRT monitors. Aside from, perhaps, casual nerdy curiosity. It's just outside of his area of expertise.
@@ColonelSandersLite oh I know, I was mostly making a funny 😄
@@ColonelSandersLite what's the matter colonel sanders? Ya chicken? Ludacrious speed now!
Turn the music down please. It is distracting.
Brings back memories of a university physics prac which involved running around campus with a geiger counter. The three highest readings I got were from a flourescent light tube (switched on), a banana, and a toilet.
was it the banana eaters toilet?
@@RovingJack the explanation I was given was both are high in potassium, so it's possible
Fluorescent tubes are evil... but I didn't realize they could be radioactive :D
The best part of this is that Brian has a piece of random old glassware that he can now use as a party trick.
Drink from the _actual, legitimate, scientifically proven _*_Radioactive Bowl_* and win four dollars!
Loved the video, great stuff. One thing: background music was a bit high. It was hard to always follow the dialogue. For whatever it's worth, lol. Thanks gentlemen, cheers
It's safe to look at.
Just make sure to not handle it with anything hard that could microchip it, then it gets embedded into your skin, stays there for a few years, and you get a dermal growth out of no where.
Reminds me of the people paranoid of 5g radiation, but go out into the sunlight every day with no worries.
Hey! Don’t science-shame them! 😉
I'd like to see this guy back! He seems fun!
What an amazing guest! Radiation 102? Pretty please?
I have a collection of Geiger counters and radioactive things including airplane dials painted with radium Vaseline plate and a regular knife sharpening stone
I have almost 200 pieces of vaseline glass its sooo awesome in a blacklight
My mother collects Vaseline glass and I’ve long enjoyed it’s eerie glow. I have some old instruments that I hit with a light and energized and they glowed for several days so I’ve just put them on the do not fuck with list.
My grandfather passed recently, and while emptying his home me and a cousin of mine both remarked that a set of drinking glasses had a color that reminded us both of uranium glass. Lo and behold, it very likely is.
I love how he reacted when he was told it was 900 CPM, and I'm sitting here like come on dude I have a airplane gauge painted with radium that has about 100,000 CPM
@@Cs137matt And CPM doesn't really even tell you anything, just having a larger detector will increase the number of clicks.
I know it's kinda hard to get radiation poisoning but those radioactive glassware are a good example of why you should be aware. It's not likely to get acute radiation poisoning but accumulative radiation can be a danger if you don't know about it.
I mean that glassware would present enormous danger if it broke/shattered, spraying radioactive particles all over the place. The real danger is probably those fake amazon radioactive-adjacent items that contain (thorium?) dust.
Regarding the glassware, it's only dangerous if you swallow it or get inside your body. Or as he stated, it's very close to your body for long periods of time. With glassware, that's not going to be the case, because we don't use them as pillows.
However! Let's say you have that glassware on your counter and your asshole cat knocks it to the ground and the glass shatters ... Now you have a potential problem. Glass particles will be suspended in the air, and as such, so will uranium. You might breathe these in, completely unaware. Larger or smaller pieces could end up in your skin.
This isn't going to kill you of course. In fact, it probably won't cause you any noticeable health issues. But you might be a little more susceptible to cancer down the line in placed where you came in contact, such as lungs, or stomach or points of laceration if those particles resided in your body for a long period of time.
There used to be something called Radium dials, which Radium was used as paint which glowed in the dark, especially for military equipment like compasses. The women handling the paint day in and day out for long periods of time eventually became very irradiated, especially after failing to be told that the paint they worked with was radioactive. Even worse, these women were instructed to put the paint brush tips in their mouths to keep the brushes pointed ... Many died because of this. They also painted their nails and skin with the paint, because of its attractive glowy effect.
I happen to have a Radium Dial in my house, the paint has long degraded to dust. if it were ever cracked and the dust leaked out, this could post a health risk.
@@Cthulhu013 Good writeup! The Radium Girls story is a heinous one -- it's one of those things that make you glad we don't live in The Past (and a little anxious that we're unknowingly doing the same kinds of things!)
Regarding the uranium cookware, the question I'd respond with is that this is *cookware*. We don't eat it, but we eat things that are in it. Is it impossible for there to be seepage from the cookware to the food?
Even without the thought of a small chuck of the glass breaking off in the food, the simple process of heating it up to 450 degrees f with some potentially acidic foods in it seems like there'd be the potential for issues.
@@bvoyelr The only acid which can etch glass is hydrofluoric acid, and that is never going to be in food or drink of any kind. Glass is not affected by any other kind of acid - even concentrated nitric or sulfuric acids can be kept indefinitely in glass bottles without a problem.
Alkalis on the other hand are another matter entirely - strong alkali will slowly etch glass. There aren't many foods which contain strong alkalis, but there are a few - the Swedish "lutefisk" is an example - white fish preserved with lye. So if you were pre-soaking a piece of lutefisk in water (a requirement to make it edible before cooking) using that uranium glass bowl, there is a chance that the alkali would etch the glass and release some of the uranium into the contents. The same would be possible for any other foods preserved with lye - there may be some others, but lutefisk is the only one I can think of right now.
Incidentally, you don't really have much to worry about with radiation from the uranium glass. A geiger counter will pick it up if held close enough, but that alone is indication that the radiation from the uranium is not very penetrating. Which is true of either naturally occurring uranium or depleted uranium: The main isotope present is U-238, with natural uranium containing about 0.7% U-235. Both of these isotopes are alpha-particle emitters, and these are the most weakly penetrating of all particulate radiation. For example, a single sheet of paper is enough to block alpha particles, and even if you were holding that uranium glass with your bare hands, your skin would block most of the radiation. In fact, most of the radiation from the uranium in the glass will be blocked by the glass itself, with the exception of any uranium atoms which are at or near the surface - it is the alpha particles from these which the geiger counter is detecting.
This was awesome. Great guest. I work as an X-ray technologist and was wondering where this was going to go. create mass hysteria or be informative. This was greatly informative people don't realize how much radiation and the sources where we get it from everyday. Wish he could put out more great general radiation information.
Fun fact, the UV light makes the uranium glass more "interesting" and from what I've found it's about 50% more "interesting"
That actually is interesting. In retrospect it should be obvious that if a black light is making something glow, it's because the thing has been excited enough to emit radiation.
Wouldn't have expected that from Uranium, though.
I'm curious what you've found, In my experience UV light, especially soft UV, has no effect on the decay of atoms.
@@YourArmsGone Same, I've found nothing written about this effect, my hypothesis is that the UV light excites the atoms and as they return to there original state they release some radiation and light but I have no way of testing this, and I find that UV-C gives the best effect.
This one ended too soon! Hope yours doing more with Jim, he’s super interesting!
6:45 god, the addition of the background noise reflects the mood so well
(Technically it's removing the background noise remover but shh)
It's a classic moment. Nice awkward pause, while the guest stared on in awe, then stopped caring five seconds after it became too long.
This was a great refresher to all the stuff I learned in school becoming a Radiological Technologist (I am the guy taking your X-rays when you do something dumb and get hurt)
excellent presentation. love the MR videos
I love watching this and getting an ad about how my phone emits "harmful levels of radiation" lmao
I love everything about this video, Portishead mention, T&C Surf Reference, making the guest awkward during a thumbnail shot... Great start to the weekend.
whats with this loud music over the explanations, but dead silence over the rest of the video????
I loved Jim! He was great and his stage energy matched your guys perfectly. I would to see him in more stuff with the rogues.
Never thought I would live to see Arcade Gannon IRL.
Nice vid!!
That 22min flew by , i love videos like that where they are so simple but so interesting that a 20+ min video feels like a short lol
You guys should do more , science/educational Adjacent videos
As someone in the nuclear industry I feel like I'm missing out by only getting like 10 mrem a year when compared to the NRC limit
SUCH a great episode!! Well done!
Awesome video!
A lot of good information, I learned a lot.
Super interesting episode! I really enjoyed this format!
Brian and Jason play with radiation? This one's gonna be good!
Definitely have this guy on again! He's awesome!!
I've talked to people who said that they refuse to buy a microwave because it will "make our food radioactive" and I couldn't even *begin* to explain how wrong that was. They also said that I had to wait five seconds after the microwave is off before opening the door, "so that the rays can disperse". I'm convinced that they don't know how radiation works or what radiation even is. If microwaves travel at the speed of light, what makes you think waiting 5 seconds will do?!?
Yes, yes, yes. More nerds please. Deeper explainations from experts are often lacking on youtube, and it only makes your fun stuff more interesting.
Jim! It looked like you had a heck of a great time doing this :) Take care, M.
6:48 Oh man, why do I relate to Professor Lohaus on this one?! 😂
Side note, on REM: Experimenting with a polyphasic sleep pattern might make for a cool video or two. :)
I just did a project for my culinary class about irradiated food and the food industry uses it to sterilize the food from bacteria and food borne illnesses and to slow the ripening process and I was kinda hoping y’all would talk about it cause it’s really interesting
Interesting as in radioactive, or interesting as in "it would be entertaining to hear an educated person talk about this topic"?
@@bvoyelr a little bit of both
Hell yeah! I like that you guys got an actual scientist!!
5:06 that took me back, now I want to play that game again.
I love this episode i wished more people would have seen this
Thank you..
Very interesting!
Best episode yet. That's interesting.
I watch it for the science, but stick around for the comedy.
Plus the fact that there's references to things I like (T&C Surf Designs, shouting "Spoon!" Like the Tick,) which makes me want to hang out with these dudes too!
I once heard about a guy, a boy scout or something, who made a reactor out of smoke alarms. Wish that was tested. Not the making part, but rather or not smoke alarms would be enough to cause significate radiation.
It's real no need to test. Even small amounts of radioactive dust when inhaled can mess you up quick.
He didn't just do this once, after the government had confiscated his little shed of radioactive horrors he then spent the remainder of his life trying to get the materials he needed to actually pull it off. Kind of a sad story.
Overhyped news. Just a lead box filled with americium that blasts out radiation, he wanted to build a reactor but did not get far enough.
Short answer: Yes.
Smoke alarms have alpha-emitting sources, which have an incredibly high radiological hazard but only if ingested. That said, it is extremely illegal to open a smoke alarm and remove the source.
His name was David Hahn.
a T&C Surf Designs reference... Nice. I have two copies of that game, and it is always a blast.
This upbeat music takes all the fun out of the subject...

I wonder if there's a way to borrow the radioactive detector.
That legend testers bit was iconic
3:28 - Sorry,had to go listen to some Portishead..So good.. 6:56 -That poor Doc.
There'd better be a 102. I want to know why concentrations of ionizing radiation 30x the background levels are only "interesting" and not "anatomy shrivellingly terrifying."
Is there a point where those measurements from the delightful machine surpass interesting and enter the world of terrifying without requiring homework?
Are interesting things guaranteed to be interesting, or after the homework is it possible that a cricket farted on the interesting thing and gave the delightful machine a false positive?
Why does measuring background radiation set the basis for what is acceptable in an area? If I'm standing in the blast crater of a recently detonated nuke, I'm pretty sure the background radiation will be at unacceptable levels. What will the delightful machine do in that case?
“420 is interesting”. I agree Brian. I agree.
Been looking for some uranium glass or vaseline glass, but it's just so expensive to buy and I don't have a lead lined display case for it. You guys should come up to Washington state and check around the top of Mt. Spokane, that's where an old abandoned uranium mine is.😁
Such an, interesting video 🤔
I don't know maybe its the radiation but this guy is giving me some Arcade Gannon vibes
Arcade is wayyyy younger, isn’t he?
@@fariondragon there's the question my friend idk lol
@@fariondragon arcade is 35 when the courier meets him
Maybe it’s just me but the music is too loud
9th grade science class. My teacher had some radioactive fiesta ware he kept in a lead box in the closet. He also had a Geiger counter.
Just a note for your physicist, the glass is normally much less detectable, it was only the increased decay from the UV light that caused a slight increase in activity causing the increased readings. Leave the glass in a dark box for a week then scan it again, it’ll be nearly nothing. Then hit it with some UV and it’ll scan much higher again.
Did I miss the part where you test the gas lantern? I just bought one and I was very curious to know what it’s readings were when I saw it on the table!
yeah. cezio 137 is from the accident in Goiânia. if you walk through some neighborhood there with an gaiger counter you can find some very interesting things. although the most dangerous waste is buried under lead and as concrete
I was interested to hear him (the scientist, Jim) state that after ten half-lives, the "substance of interest" would be gone...we were taught five...curious if the standard changed or if we were taught wrong...
I like the radioactive taco truck. The Ciesta burrito got me!
Love it, but the bacjground music is too loud and distracting :(
7:02 Hey, that looks like my old Microwave. lol
great video ... but i feel like the music i really loud compared to the talking, especially in the begining when doing the breakdown of radiation.
6:45 completely obliterated my sides
I'd be more worried about heavy-metal poisoning from that glass than radiation, if I'm honest.
I got about half a rem in four years working in #2 main machinery room on board the USS George Washington.
i know it was a gag skit, but i kinda wanna see a radiological themed food truck. Livin' that Fallout life. Who else wants some 'squirrel bits' despite the fact there have never been squirrels in any Fallout game?... :P
Brian, the bus doesn't look like a train car to me at all.
If it helps: that’s the one part we know for sure: it was a train car converted into a diesel bus
What would happen if the uranium dish shattered? Would the glass dust and fragments be a danger as they could be missed in cleaning and cling to people?
No this amount of radation is completely harmless the increased risk isn't even worth the most paranoid of people to worry about you probably expose your self to more radation going out side for q minute than you would carrying a lot of the dusk it's radium you need to watch out for qnd if you ever come across cobalt your already dead
Jell-O is a brand, what's the product?

Frame rails and ledges underneath. Any piles of rust or debris may fall on lawn. Just a thought for pets or kids playing
My dream is to teach you guys about food one day.
"waves or particles" "both. they're the same thing" is exactly the fuckery i had to get into when i did my physics A levels
Definitely wouldn't eat out of that dish before I did more research on uranium oxide leaching and heavy metal poisoning. Safe to have on a shelf as a curio though.
What's with the music playing over the guys talking...
Theoretically, even if the car was exposed to irradiated fallout particles, there's a thing you can do called washing the vehicle, which would remove most or all of those particles, at least on the washed surfaces.
From what I've heard eating out of those uranium glass things is no big deal... Of course you have to remember that in addition to being kind of radioactive, the uranium is a conventional toxin like lead, but we eat/drink from lead glass too (it's called "crystal")
Me: *watches every episode of TMR and Scam Nation the moment CZcams shows them to me*
CZcams: "New episode of TMR, uploaded....2 days ago."
And don't tell me about the stupid bell. I don't want to have to clear notifications on my devices just for CZcams to put content it knows I want to see on my front page.
tbh the uranium glass is generally safe. i wouldnt use it every day but occasionally is fine
I couldn't watch this one due to the background music, made it uncomfortable for me to concentrate.
