[@ducttapedress98]

Honestly this was really well made. I'm watching it simply because I was curious what radiation really was. It was easy to follow and really simplified the explanation! Thanks

[@rEsonansDx]

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

[@dunno4550]

Yeah... God damn it! I want a teacher like this one :c

[@jackvantice7561]

Dunno ya know she was probably reading off of a thing

[@rcatstott]

i agree =D

[@rcatstott]

you should look up vsauce it has alot of science and alot of other fun stuff enjoy :)

[@dunno4550]

Jack Vantice Well yeah but that doesent mean she cant make studying interesting. I mean, my teacher, when she forgets something like... a page we should check in our books, she reads it from a paper. Thats kinda the same thing...

How did I know that this would be the first comment I'd see if I scrolled down to the comment section?

[@ateela15]

I can just barely grasp this due to being away from this type of information for years, but hearing the terms again is reawakening my memory a bit.

[@InAnotherLife90]

Lmao huh?

[@yassinghareeb5761]

Same, my department is the farthest from chemistry, which makes it fun to reacknowledge this.

[@pointerish]

"...or high level like X-Rays or Cosmic Rays from outer space." That escalated quickly.

[@fonzcorp]

Watching this i realized why I almost immediately vomited when I was injected with that stuff that MRI scans see in your system! Wow! HBO's Chernobyl sent me here btw.

[@Summz24]

Ditto

[@raisins7976]

[@amirfmaster2515]

[@KokoLoko-km9ep]

Same. Got me thinking about all the forms of radiation and energy we expose ourselves to.

[@erikkurasukin9907]

No way I'm here from that show too! xDD

[@buzaldrin8086]

That famous line from "The Day After": Daddy, what's radiation?"

[@Torvaxx]

3 years of notes and homework for "practice" and I still couldn't grasp this concept. Then this easy, simple video taught it to me in 5 minutes. How can school mess up that bad, Jesus.

[@RedJonathon719]

Ye I know

[@nbydummy9157]

you really thought the dropping a deuce sound effect was needed here eh?

[@thewandering525]

I didn't get it, tbh. They could have provided a visual.

[@Lilliaace]

This sums up my grad school textbook chapter in the best way possible.

[@jordon_9333]

Half-life? Half-life 3? Half-life 3 confirmed!? Knew it.

[@eviremmerswaal1154]

around 1:35 she says, sometimes isotopes have to many neutrons, which makes them unstable. Then don't use Oxygen-17 as an example. This is a stable isotope.

[@cdv3401]

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)?

[@laraahmed970]

[@rustyhoops]

If my teacher looked like that I would have listened all day long 😍😍😍😍😂😂😂

[@hanif2285]

This video was more lucrative than Stanford lectures. Thanks! 😍

[@khanderaojogdandclasses406]

I was confused about the radiation but you have cleared my concept Didi thanks for the genuine guidance

[@veggietale7207]

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.

[@doyourbst]

A wonderful way of explaining the process of radiation.

[@genepreston6025]

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]

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]

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...

[@genepreston6025]

lennyfloss 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. Forbes (5/4)

[@lennyfloss]

Yea I heard about that report. You should read this analysis of it: www.ianfairlie.org/news/new-unscear-report-on-fukushima-collective-doses/

[@genepreston6025]

lennyfloss 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.

[@CarloRedl]

Best vid ever. Saved me from failing test. THanks!

[@muhammadzainulabydeen52]

Nice explanation

[@johnblake4523]

Great video -- thanks Canada, thanks CNSC!

[@kevinbundy9154]

WELL DONE!

[@petermarch2357]

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.

[@kevinbundy9154]

Peter March They obviously made some simplifications and generalizations to appeal to the general public which I thought they did very well. If they produced it to the level that you are suggesting, no one would watch it.

[@barnard8139]

Peter March I would be very interested to see your video if or when you decide to produce one. You sound very knowledgeable and it would be a shame to keep it all to yourself.

[@gamerdude1246]

It doesn't become simpler than this..

[@like-icecream]

No it does, radiation is atoms falling apart and the reason radiation is dangerous is because it destroys the DNA and cells.

[@AlexisRestless281]

Dem but why tho?

[@like-icecream]

because they're small enough to cause damage to dna

radiation is the transfer of energy by electromagnetic waves. it is a type of energy transfer like conduction (transfer of energy through molecular motion) or convection (transfer of energy through movement of mass). :D

That sounds a lot like kinetic energy.
