What is Radioactivity and Is It Always Harmful: Explained in Really Simple Words
Vložit
- čas přidán 9. 03. 2021
- Radioactivity is the property through which a heavier, unstable nucleus assumes a more stable state by emitting radiation. The process through which a nucleus turns into a stable one is called radioactive decay. But is radioactivity or radioactive radiation always harmful? Let’s discuss this in more detail.
Inside an atom’s nucleus, there are positively charged protons and neutral neutrons. These nucleons are held together by a “glue” called the strong nuclear force. This strong force cancels out the repulsive electrostatic force of like charged protons and keeps the nucleus stable. The nuclear force has a short range of action and is dependent on the ratio of neutrons and protons present in a nucleus. However, we see that the balance between the forces starts to waver in a nucleus where the number of neutrons exceeds the number of protons. A nucleus that exceeds the threshold number of neutrons and protons that the strong nuclear force can hold together comfortably will be more unstable.
More specifically, these scenarios give rise to unstable isotopes of elements. Just as your body, through a series of expansions and contractions, expels a substance with a sneeze, similarly, the unstable isotopes of elements fling out different particles or forms of energy to restore balance between the forces in their nucleus. During this process of attaining stability, they change into a new nucleus. It is exactly this property, namely turning into something new to attain stability, that we call radioactivity.

In the video, it's implied that ionizing and nuclear radiation are the same thing; but what about x-rays and UV-C rays, they are ionizing for sure, but are they nuclear?
You're right, that is misleading. We've added a pinned comment pointing that out. Thanks!
Thank you for your reply :)
@@Scienceabc I don't find the comment?
@@keziagreste I think they mean they pinned the comment pointing it out
@@someguywithopinions Oh right! I realised so thanks!
Omg this video was presented almost perfectly and finally taught me what is rdioactivity we always hear about. Thank you!
I feel sorry for you who now believes you understand radioactivity. This video explains nothing, indeed it propagates erroneous notions (see the issue of "unstable nuclei" the way it is NOT discussed here.)
@fgcbrooklyn where can I fund valid information
This was particularly well done. Thank you!
Glad you liked it.
Exactly, it helped me too much
This is better taught than my teacher currently at school! Thank you so much!!
True
A pretty low treshold.
Curie discovered radioactivity, but at what cost!
Curie didn't Becquerel did. Curie discovered radioactive element. That is why, SI unit of radioactivity is Becquerel.
Curie found the cure of cancer from radioactive if im not mistaken
Everything LMAO
@@realgnabnahcgf mafie curie Discovered radio active element Like radium polonium and in contact with it marie die and bekural was the first person To diacovered The dis advantage of radioactive element Hope its clear 😇
whatever the cost
Maria SKŁODOWSKA - CURIE była geniuszem, w 8 lat 2 Nagrody Nobla z fizyki i chemii. Ta Polka zrewolucjonizowała radioterapię, jej wynalazki służą ludności. ❤
What a well presented discussion ; a complex subject made into a story with everyday examples and illustrations.
what do you do for a living? i need friend like you.
Pani Maria nazywała się SKŁODOWSKA - CURIE, była Polką. Pierwiastek POLON nazwała na cześć swojej ojczyzny Polski. Wielki szacunek 🇵🇱
Nice video 👍. On a side note, the Marie Curie cartoon is really nice
Quite insightful!😎😎
It has the right amount of resource with great quirk and innovation!
Glad you think so! Do subscribe to our channel and share the video with your friends.
There is no "insight" in this video. But, I understand. your knowledge of the English language equals the videomaker's knowledge of particle physics.
The Geiger counter sound in the end is terrifying me
idk why but that sounds doesn't disturb me
@@SEA-hp6zo oh u should be worry
Absolutely, this is the outstanding method of teaching and learning...
Glad you think so!
this video deserves a million likes.. incredible way of teaching and editing skills are amazing
my teacher can never explain so easily he just loves to complicate easy things... aaagggghh
Great video. Easy to understand, accurate and entertaining. Keep it up!
Glad you enjoyed it! 😊
7:22 those Metal Slug sounds
Great insights! Wonderful presentation.
Glad you enjoyed it!
Great video!! Thanks for the simple explanation :)
Thanks, I have been hearing this word my entire life while never knowing the true meaning and detailes about it
I have a question about your time dilation video and idk who else to ask to get an answer because i don’t know any physicists. You say the head is older than the body because of gravity, but how is that? Would that only apply if you jumped? If not, how can the feet be accelerating more quickly and thereby be slightly younger than the head? I also wondered why the head wouldn’t be younger because of the rotation of the earth meaning the head is moving more quickly than the feet by rotation. Any answer would be very appreciated!
Wonderful explanation! Thank you so much
Finally a well explained video
hey! small doubt, gamma rays have 0 relative mass and charge and they mentioned that emissions are because of instability in nucleus because of n/p ratio but since gamma rays don't alter that ratio, why are they emitted ??
This is very great and exquisite. Makes it easy to understand and very unambiguous.
The subtle fear of Nuclear power is still evident in the fact that it misrepresented the two examples of reactor disasters. The japan accident had no fatalities from radiation. And funny how they made the Chernobyl meltdown look bigger than the "four-square-mile radiation zone." Moreover, the video ended on the fear note-- not subtle.
Agreed, I am super sceptical of things, espically after watching the docu American Moon.
I am affraid may things will never be fully understood by me, because I don't have the time to become an expert in every field.
However If Thorium reactors are the reall deal we will have energy for 1000's of years !
chernobyl is a literal wildlife sanctuary these days lol
Well explained. Kudos....

Keep uploading such informative videos.
Can you please explain everything about tachyonic antitelephone. Plz plz plz 🙏🙏
best explanation ever
This is interesting and academically uplifting. Good for the future of the earth.
I love it. Your job!!
Thank you so much,it's better now
Simple explanations with great graphical presentation and narration. Easy to follow although I've forgotten the facts already!
Good explanation!
Loved it! great explanation 🤩
super job thank you
this video is so underrated
I have underestimated mrs. Marie Curie now I know the truth thanks for your vedio
How about stoping calling her Dr. instead?
all i was doing was laughing. great efforts
Thanks 😅
Well done
Your Videos deserve more views and your Channel deserves more Subscribers!!!!❤️❤️❤️Keep making more videos!!Love you all!!! 🙏🙏👍👍
Thank you so much Nihaal!! Do share our videos with your friends if you like them.
anyone who works in rad knows that the end of the video had us all triggered by the noise of the frisker going off
Well explained.. makes it easy to understand...
Helpful.Thanks ❤❤
Perfectly explained.
Glad you enjoyed it 🙂

Such a well made video. Congratulations to the team?
Thank you so much 😀
Tq sir
07:26 metal slug sound
the sneeze anology is deep lol
This video is gonna blow up. Since i commited early it will get alot of likes then i will say "omg ive never had so many likes b4" this is annoying and should be stopped.
Lmao how did that work out for you
Epic video
جميل جدا
شكرا لك
لقد اختصرت وحدتين في كتابي المدرسي فيزياء ٣-٣
who else is being forced by their teacher to watch this
Nobody. Just you.
So basically you're sayin that Spiderman can never happen?
may god bless you and ur next 10 generations
Hi I had radioisotope for x-ray...twice . Got very sick. How to clear this, please??
Medical intervention is 3th death case in usa already. Not all that we are believed to be told is true.
If you want know more about rockerfellar/modern medice you should watch video of "corbett report" (banned from youtube)
This is really great🎉❤
Beautifully explained 👏
Every thing on Earth has a good and a bad side. Like radiation, radiation is used to treat cancer and fend off many other diseases, but it also has a bad side. Nuclear bombs that kill thousands and millions in just one single explosion. Nuclear reactors that are producing power but if a meltdown occurs will infect thousands with radioactivity. Nice explanation though! Keep up the good work ! 😁😁
If I was in the target of the second with no hope of escape, I hope I'm one of the lucky ones.
Liked your video, well explained
According to the CDC 1.5 million people are hit by cars every year but whenever people talk about cars Maryville to understand that's it's not the vehicle itself but how it's used but nuclear energy doesn't get the same treatment for some reason
Whats actually happening in the air around you thats making the area radioactive? If what radioactivity is, is energy being fired off, why does it stick around in the air so long?
*It's not into the air but the things around the radiation & exposure of it cause the radioactivity.*
How is the first neutron produced in nuclear reactor
When you think about it, there is no rational explanation for the behavior of atoms. Why do they act the way they do? What governs these patterns? It raises the question of whether all of this was deliberately designed by a higher force. The universe is teeming with meticulous details, offering boundless creative freedom akin to an artist's canvas. There exists an inherent order so deeply woven into existence. It can’t be a coincidence.
This has helped me
Radioactivity was discovered thousands of years ago by Indus valley sages and academics. There's mention of Brahmastra in the Vedas which invokes in the form of a fiery ball of lightning and can be manifested in anything from a blade of grass to the tip of the arrows. This knowledge was so secretive and forbidden that only few remarkable people could manifest this power. Mahabharata has mentioned 4 such people in ancient times. It was kept forbidden because of the immense destruction it causes. It is explained that after the impact of the Brahmastra nothing grows in the area every living thing perishes and nothing will grow there for 12 Brahma years. It is said in the Vedas that the world will come to an end with a Brahmastra which is ironically evident in today's time
i dont understand why they destroy whats ours, earth , lands, destroying wirh bombs and wars just to own them but such massive distruction that leaves the land with nothing livible for generations. i wish humans were aware of their actions to environment and used it to better the life and not for distruction of it
Completely incomprehensible to people who don't have at least some knowledge of the strong force and the interaction among nucleons. AND, absolutely useless for people who have that minimal knowledge.
Thank you!
Wowww😮😮🙌🙌🔥🔥
Very nice
so, gamma rays are basically light on steroids, a lot of it.... got it
Is it the same material that radiating from the sun during a total solar eclipse?
I thought I read somewhere this upcoming total solar eclipse in April 2024 will have the same effects or is that different kind of energy. My apologies for not being clear, this subject has been a little bit of a mystery to me lol
7:24 only true metal slug fans can recognise this dying sound❤️
Does life in fact need radioactivity? If you removed all of it, it'd alter the environment in your cells quite a bit I imagine. Since it breaks molecules and ionizes stuff, I imagine that there could be biological processes that wouldn't work entirely properly in the complete absence of ionizing radiation. You might perhaps even get quite ill in an environment where you were isolated from all radioisotopes and external sources? Even if you made UV-B an exception. Life has a tendency to throw curveballs, could it be our bodies secretly make use of natural decay in subtle ways?
There's still many things not being cleaned up here.
The more I learn about science the more I’m convinced that most things are just magic. Invisible energy that can either heal or kill you? Definitely magic.
You heard about jinns?
Thank u🔥🔥🔥🥂🥰🥰🥰
Nice
I’m Arab for Saudi Arabia and my English is kind of bad no let’s just say my English is bad and the thing here is why I understand and get the lessons in English but not in Arabic for me i fell that it’s because you r drawing while explaining the lesson 😅 anyway I don’t know I just know that I can understand in English butteer more than Arabic ☺️thx tetcher ❤❤❤
There is more radioation than alpha,beta and gamma,for example electron capture or neutron emission. Also alpha is actually the most dangerous near the body because of its big size.
Poor mark...
Nicee
I loved itt great 😊
Thanks 😄
Is the video have no sound or it's happening with me only
Maria Skłodowska-Curie*
Bro literally explaining that how Bruce banner become hulk?
Wow
It's is spontaneous emissions of alpha or beta AND gamma radiations

Radioactive power is dumb, we can easily use won’t and water to make all the energy we need.
Radio active
👍
is bill nye reborn?
❤❤❤
Funny, that the uninhabitable Chernobyl is actually inhabited.
I don’t understand this, I wasn’t in school when they were teaching

Almost gave a thumb down, references to b.s. comic characters. With no' explaining, that those stupid shows are all false. & what actually would happen to someone, in same contexts. Not separated latter in review.
