She says everything with a smile like I know wtf she’s talking about

I can't be the only one who thought she was going to say "but many of us just weren't paying attention."
Ok
Jose A. Mendoza-Huijon ikr
Hahaaaaaaaa
lol, i thought that too
Lmfao same
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
2:23 Half-Life 3 confirmed
Ey lmao
She said 3 half life, OMG
ayyy
tf2 at start
How did I know that this would be the first comment I'd see if I scrolled down to the comment section?
When taught in school - It takes one quiz to fail before understanding the basics of the topic
When taught in UA-cam - It only takes 5 mins to understand the basics of the topic
#IHateSchool
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...
That famous line from "The Day After": Daddy, what's radiation?"
"...or high level like X-Rays or Cosmic Rays from outer space." That escalated quickly.
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.
Half-life? Half-life 3? Half-life 3 confirmed!? Knew it.
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.
Ditto
Chernobyl is love
Me came from HBO too
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
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)?
This sums up my grad school textbook chapter in the best way possible.
Excellent presentation. Thank you!
Teacher: *explains something for 2 hours*
Students "I sTiLl DoNt GeT iT"
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.
Ye I know
Thanks so much. I had great understanding about Radiation and Radioisotope.
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.
I'm amazed at how simplified this was.
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?
This video was more lucrative than Stanford lectures. Thanks! 😍
A wonderful way of explaining the process of radiation.
Great video -- thanks Canada, thanks CNSC!
I was confused about the radiation but you have cleared my concept Didi thanks for the genuine guidance
*I love videos like these! Thanks!*
Thank you for the explanation
Perfect!! Thanks.
If my teacher looked like that I would have listened all day long 😍😍😍😍😂😂😂
Thank you ma'm for giving me the information about the topic I was having confusion about...☺☺☺☺
Thanks for the vid! Helpful!
Nice video! I enjoy your tutorial thank you so much.
Well explained! Thanks
Best vid ever. Saved me from failing test. THanks!
hahahaha nice joke
Thanks for the clear explaination😀🙌
The Glowing Sea has a lot of this stuff.
+Freeze Cryo fallout refernce
i throw some nuke grenades and kill those radscorpians and deathclaws
^^^
+Moctopus lol ikr
+ProG Cryo Another settlement needs your help
So helpful for my project thank you!!
I wish I had youtube when I was in school. (so much easier to learn) Thanks!
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!!
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?
Well explained! Thankyou
Nice and well explained :)
thanks for your explanation
I have studied this about 3 months in school but I understand it better in 4 minutes video.
Thank you very much!
Nice explanation
Very well explained, Thanks :)
amazing ❤❤ great explained
At school l can't understand anything but when you teach me I got it in 5 minute
Thank you🙋
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?
Great vid! Interesting!
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!
Very well explained...
Great explanation 👍
I learned more here than in school
This was great!
Which software do you use
Now I want a jelly bean
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?
0:52 this is why people think science is lame
shin1300 lmao that was so cringe
?
Thank you!
Thank you for saving my life
What happens if you ionize or electrify a neutron inside an atom tho
you're a cool teacher, I've understood everything like its my native language
thanks for your information it's very basic though
Is there a way to reject space? And use that rejection as propulsion?
Outstanding.
When you have not been in high-school yet ; )
WELL DONE!
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.
na tay kis shay da ????????? tenu smjh a gai
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...

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)
Yea I heard about that report. You should read this analysis of it: www.ianfairlie.org/news/new-unscear-report-on-fukushima-collective-doses/
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.
Good explaination
i love this. thank you
My three and five year olds love this.... Their favourite bit is the flush :-)
Right when I started watching this, tornado sirens start going off! lol (they're just testing btw)
Wow man nice... Explained..
I love this girl ,in the way she taught
"I'm a wanderer, Yeah I'm a wanderer."
FINALLY someone who explains it and I get it. Thank you.
i like this very much
thanks canada
Does heat transfer in vacuum or not?
Really cool dude that was epic
Thank you so much, now i understand what is radiation 🙏🏻!
thanks a lot
Since i saw no comment of IT, I would do the honors "HALF LIFE 3 CONFIRMED!"
Will you provide some study material of radiation.
can we use Gama ray as disinfectant for drink water ?
thank you.
.
I love your teaching
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).
I LOOOOVED THIS.
This helped allot
how do i explain what is a "charge" give me some analogy pls
What I really wanted to find out is the difference between particle and wave radiation.
we could able to understand everything from this video
wow thank you soooo much now i really understand IT
I've learned more aboat radiation from this fine canadian than my high school teacher
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?
Wait, is that from where the games half life name was born? I mean it has radioactive rivers
Do all Canadians learn chemistry in this way? They are too lucky
Nice video.
Now I know how half life got it’s name, thanks
Are you concerned how superposition loose its probable dessity
