    When taught in school - It takes one quiz to fail before understanding the basics of the topic
    When taught in CZcams - It only takes 5 mins to understand the basics of the topic

    So I'm still confused about why some substances are more hazardous than others when it comes to radiation. Surely right now all around us, there are some atoms in the air that are undergoing radioactive decay but are not harmful to us. Yet, if you had prolonged exposure plutonium you would become ill very fast. Is this due to the Alpha, Beta, and Gamma particles that were discussed in the video? Is it that some substances release massive amounts of gamma particles while others only less so (I recall gamma waves being very hazardous to your health)?

    Did you ever hear the tragedy of Darth Plagueis the Wise?
    I thought not. It's not a story the Jedi would tell you. It's a Sith legend. Darth Plagueis was a Dark Lord of the Sith, so powerful and so wise he could use the Force to influence the midichlorians to create life... He had such a knowledge of the dark side that he could even keep the ones he cared about from dying. The dark side of the Force is a pathway to many abilities some consider to be unnatural. He became so powerful... the only thing he was afraid of was losing his power, which eventually, of course, he did. Unfortunately, he taught his apprentice everything he knew, then his apprentice killed him in his sleep. It's ironic he could save others from death, but not himself.

    What's missing is a discussion on what levels are safe and what levels are hazardous. For example some naturally occurring locations of radioactive decay have much higher levels of radiation than the levels normally thought of as being hazardous, yet there is no evidence the local residents in those locations are being harmed. This is the real message that is needed, not a lesson in physics. Also it would have been much better to show the units of measurement such as uSv/hour and typical background levels. All of us are bathed in radiation all the time. Experiments show that the body is not harmed by low levels of radiation. There is a cutoff point though. What is that level? Well we don't know because the insistence of government agencies to rely on the linear model, that radiation is harmful all the way down to 0 levels, but this is not factual and is not backed up by experiments. See Pandora's Promise to get an idea of typical background levels. But don't spend much time in Rio because its more radioactive than some parts of Chernobyl that is off limits, well except for locals who have crept back in.

    • @Harizl
      @Harizl Před 10 lety +4

      Well, most studies have shown that due to it's semi-unpredictable outcomes, radiation is treated linearly due to exposure outcomes vary greatly from person to person. It may be outdated, but it's not as if there are non-trivial reasons to overcompensate versus possibly under-compensating.

    • @lennyfloss
      @lennyfloss Před 10 lety +3

      The National Academy of Sciences released the BEIR VII report, which proved that the LNT model is accurate at low levels: 0-100 mSv. There is no safe dose. And the Petkau effect? Hm...

      What about this report? www.forbes.com/sites/jamesconca/2014/05/04/cancer-and-death-by-radiation-not-from-fukushima/ U.N. report confirms Fukushima radiation will not cause cancer, scientist says
      A report from the U.N. Scientific Committee on the Effects of Atomic Radiation acknowledges that "no one will get cancer or die from radiation released from Fukushima, but the fear and overreaction is harming people," writes scientist James Conca. He argues that the Japanese people can now begin "eating their own food again, and moving back into areas contaminated with radiation levels similar to many areas of the world like Colorado and Brazil." He cites several facts related to Japan's Fukushima Daiichi accident, including the low level of radiation present in all foods produced in Fukushima prefecture and Japan's efforts to restart its nuclear fleet.

      Whats lacking in those low dosage assumptions for long periods is the ability of the body to repair itself. There are monks living at high altitudes who do not suffer the cancer rates but are exposed to continuous high radiation for long periods.

      Amazing that such bad science passes muster in Canada. The atom as a planetary system has been debunked for half a century at least, the idea that all the universe is made of atoms is ridiculous, equally ridiculous is the idea that scientists themselves think they understand radiation. Getting a smug actor to talk such outdated rubbish is further proof of how disgracefully misinformed we are.
      The fact is that quantum theory is in a death struggle with relativity and radiation is the very heart of the problem. Would we be tolerant is someone told us that communism evolved as a response to the Christian desire to share? or if the cheery little girl told us that money is just paper (it isn't even) so it's silly to think we don't understand it! " It's just paper" grin, grin. It's hopeless. How sad. And our teachers are paid to mouth off all this drivel.
