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
When taught in school - It takes one quiz to fail before understanding the basics of the topic When taught in TH-cam - It only takes 5 mins to understand the basics of the topic #IHateSchool
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...
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.
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)?
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.
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.
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.
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.
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...
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 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.
I been using Internet from my 12th grade no video has given me a clear cut explanation...i mean not only this topic so far all types....thanks sister!!
So if deionized is "safe" forms of radiation vs ionized radiation gamma rays having plus 1 or minus 1 proton could you theoretically neutralize or deionized harmful radiation such as Fukushima by applying a negative charge across the plane of affected area?
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
hi, I from colombia, I have a question about of radioactive decay; it is: what happens with the energy released by the atom when it decays in the human body? and the body absorb this energy?
A small doubt...................correct me if im wrong.......will all the radioactivity go.............like......wont there be a half remaining??? (In the gamma radiation injection scene).
They didn't mention anything about how Radiation can possibly flow throw most Solid Objects, nor how or why Lead is a reasonably decent shielding material and cuts the effectiveness of radioactive decay.
i dont understand the decaying process. i mean why is it going half and half and half? arent all the atoms existing at the same time? shouldnt they decay all at the same time?
Thanks to movies and video games, many of you have heard about radiation... but because of your public school education many of you may not know exactly what it is.
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.
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.
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.
i wish i would learn harder in school and could be clever today, being a doctor or a scientist. I always mess up every of my first characters in every game.. too bad i cant start a new life.
I’m curious as to how radio active material is dangerous to humans? If we take the Fukushima disaster in Japan as an example - where in the “air” is the radiation?
I like the video, but didn’t explain what alpha, beta, and gamma are in greater depth (electron, helium nucleus, and EM wave I think), and didn’t even mention neutron radiation. Also, what is ionizing vs nonionizing beyond a vague “harmful/ non harmful”.
How would you speed up radioactive decay to eliminate the radiation from nuclear waste? Is there a better way to dispose of nuclear waste rather than just burying it so we can protect the environment?
I need some help please. She said that a radioisotope is an ATOM(with an unequal amount of neutrons and protons) But later she goes on to say that "half-life is the amount of time it takes for half of the radioactive atoms in an isotope to disapear" But an isotope is an atom. So what she's really saying is that "Half-life is the amount of time it takes for half of the radioactive atoms in an atom to disapear. That doesn't make any sense. Does she mean particles? What's going on
She meant that half life is the time it takes for half the atoms of a determined amount of a determined substance to dissappear (in order to do so, those atoms need to be isotopes).
Henrik Jensen The radioactive substance isn’t disappearing, it’s emitting its neutrons, beta particles or gamma radiation. A half life is when half of the element emits their particles to the next stable level. Sometimes the next stable level is another isotope or sometimes another element. There is an ideal balance of neutrons and protons but not necessarily equal in number. The most stable form of hydrogen has one proton and no neutrons.
I seem to have ingested cold medicine which possibly built up a potential radio active particle. I ate a few jars of pickles eating the whole jar. I find it possible to have a radio wave attached to my body. It makes my stomach and other parts of my body twitch. How do I get this radio signal to detach. I seem to block it for awhile but it keeps coming back. It seems I’ve found ways to energize the signal. Please help me better manage and shield signals causing potential Parkinson’s.
She says everything with a smile like I know wtf she’s talking about

Yeah... God damn it! I want a teacher like this one :c
Dunno ya know she was probably reading off of a thing
i agree =D
you should look up vsauce it has alot of science and alot of other fun stuff enjoy :)
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...
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.
Lmao huh?
Same, my department is the farthest from chemistry, which makes it fun to reacknowledge this.
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.
"...or high level like X-Rays or Cosmic Rays from outer space." That escalated quickly.

Same. Got me thinking about all the forms of radiation and energy we expose ourselves to.
No way I'm here from that show too! xDD
This sums up my grad school textbook chapter in the best way possible.
Half-life? Half-life 3? Half-life 3 confirmed!? Knew it.

I was confused about the radiation but you have cleared my concept Didi thanks for the genuine guidance
you really thought the dropping a deuce sound effect was needed here eh?
I didn't get it, tbh. They could have provided a visual.
uuh, wasn't that just a toilet flushing?
If my teacher looked like that I would have listened all day long 😍😍😍😍😂😂😂
This video was more lucrative than Stanford lectures. Thanks! 😍

Best vid ever. Saved me from failing test. THanks!
hahahaha nice joke
I have studied this about 3 months in school but I understand it better in 4 minutes video.
A wonderful way of explaining the process of radiation.
Okay, but what does the type of the radioactive decay particles depend on? when will the atom release Bata when will it release Gamma and Alpha?
So if deionized is "safe" forms of radiation vs ionized radiation gamma rays having plus 1 or minus 1 proton could you theoretically neutralize or deionized harmful radiation such as Fukushima by applying a negative charge across the plane of affected area?
*#Radiation** is the mode of transfer of heat from source to receiver without heating the medium between them*
Thanks for the clear explaination😀🙌
She really broke it down
Now I understand what radiation is all about
FINALLY someone who explains it and I get it. Thank you.
Thank you ma'm for giving me the information about the topic I was having confusion about...☺☺☺☺
Does heat transfer in vacuum or not?
I never thought that the Canadian Nuclear Safety Commission would help me with my science exam.
Well you shouldn't be playing too much MineCraft and start REVISING!
Perfect!! Thanks.
I wish I had youtube when I was in school. (so much easier to learn) Thanks!

That sounds a lot like kinetic energy.

Will you provide some study material of radiation.
When you have not been in high-school yet ; )
Lol I did not understand anything xD
Same
It doesn't become simpler than this..
No it does, radiation is atoms falling apart and the reason radiation is dangerous is because it destroys the DNA and cells.
Dem but why tho?
because they're small enough to cause damage to dna
I've learned more aboat radiation from this fine canadian than my high school teacher
Is there a way to reject space? And use that rejection as propulsion?
I learned more here than in school
Which software do you use
Thank you for the explanation
we could able to understand everything from this video
Now I want a jelly bean
Nice explanation
What I really wanted to find out is the difference between particle and wave radiation.
I want to become radioactive!

So she means "an equal amount of neutrons and protons" instead of atoms

thanks for your information it's very basic though
aside from all the video editing and mindless comments, I want to see the part where we learn how this radiation affects the body

carocuno06 that’s not how radio waves work... or radioactivity. Try reading up on some basic physics.
Great explanation 👍
Very well explained, Thanks :)
if i go to the most radioactive places on earth, i will be radiated a lot, but will the radiation fall off in time or stay with me permanently
