Radiation Rays: Alpha, Beta and Gamma 

This is how you make a science video: straight to the point, no intros, just pure information. Would be so good if science videos that deals with human behaviour were this straightfoward.

Some one : "Hey I'm gonna shoot a alpha ray at you" Me : *holds up piece of paper* "no please don't"

Watches Chernobyl once... Becomes Nuclear Physicist through RU-vid

Comrade Diatolov says gamma radiation is only 3.6 roentgen, so nothing to worry about.

Hi, Barium symbol is Ba. Br is Bromine (@3:40)

How bad are these types of radiation? A - all right B - bad G - god help you Edit: the people who didn't understand the reference to the penetrative ability rather than actual harmfulness (and it's freaking joke) probably suffered brain damage from said radiation

Now that I know how Radiation works, I don't need you.

The doctor : X-Ray is real, but it can't hurt you Me : ok The doctor : *hides behind leaden walls*

3:03 watching that animation is so satisfying. Its so well made and explain fission so well

I always thought that Alphas were the one that did all the penetration.

We can't just say that radiation is or isn't stopped by a certain type of material, as it also depends on how thick the material is, and the radiation is attenuated further the further it passes into the material.

0:11 - these are certainly the common ones, but there are others: neutrons, protons, positrons, and miscellaneous nucleus fragments, including the nuclei of 20-30 other elements known as fission products. Any or all of them can cause damage to biology due to ionization within stable molecules, and creation of free radicals. 1:30 - in reality, all three radiation types you mention can have energies which allow, for example, an alpha particle to penetrate an iron plate. The shielding you mention is appropriate for radiation emerging from decaying nuclei, but are very under-representative for primary and secondary cosmic rays. The thicknesses of the materials are as important to their ability to stop radiation as the materials they are made of - paper, aluminum and lead. Air and water are also effective shields, in appropriate thicknesses. There is no absolute shielding, a small fraction can always pass through, smaller as the material gets thicker or more dense. 2:30 - Those "protective materials" are generally not really protective at all. Paper gowns, HAZMAT suits and the like will, of course, stop almost all normally energized alpha particles, but they will do little about betas and gammas. The real reason such protective gear is worn is mainly to prevent (by removing the gear upon exit) tracking the dangerous materials home to decorate your car and house with. The exception to that is a respirator - it acts to keep small particles of decaying atoms out of the lungs and digestion, where even alphas can cause trouble.

First off, a correction. Alpha and beta are particles while gamma is indeed a ray. Neutrons were touched on but they are also a radioactive particle. Alpha has the most damage potential but are slow moving and have no penitration ability. Beta is very fast but mostly low charged so less damage. Think of a thrown basketball (alpha) and a 9mm bullet (beta). Gamma can't be fully shielded again as it's charge can only be lessened by hitting other atoms. That is why lead is used as shielding because denser material has more atoms packed together to increase the chance a gamma ray will interact with the shielding. That's enough for now.

Best fission graphic I have ever seen. Awesome video

I watched HBO's Chernobyl, twice! I now feel comfortable educating others about nuclear radiation.

The best video I’ve found so far on radiation. RU-vidrs and videos go on a long winded and difficult to follow approach on the three main types of radiation. This one is crisp and straight to the point. Thanks!

Every time I had a question, this video went on to answer it. It's like mind reading. Thanks

i got more knowledge from this video about alpha beta n gamma rays. thanks

Great vid, thanks. Loved the animations for the Ur-235 atom splitting.

Great work!

What a good video! I have read about and watched videos on how all of this works, but this video made it really easy to understand.

Great video! Keep up the great content

Damn that was a really good, concise video

RU-vid recommendations made me a nuclear physicist

Thank you very much for this amazing explanation!! Really helped me out :D

Thank you for this explaination! Really helpful

Thank you Sir for this video .This is really informative.

Than you so much sir for making this video . It realy made the concept very easy to understand .

Thanks very much,greetings from México.

Thanks. I couldn't understand radiation and then I watched this video and I got it.

Well explained!

very nice sir you deserve a lot .

Very nice and interestig! In which program do you make this simulation? It looks really great.

1:54 Jesus... I think our bald friend has been exposed to too much radiation from the waist up!!

excellent explanation. Thank you.

Very good Explanation

Thank you it really helped 👍😊

I remember I used to play with this early 1900's chemistry set as a kid. And I saw a video about the same kit and it being extremely Radioactive. Probably why my ex brother-in-law died from cancer at 33. It was his kit. I remember one vial that glowed green when the lights were out.

great video

Explained better in one video than a couple days in school

This is extremely simplified. There are many more types of ionizing radiation aside from Alpha, Beta and Gamma. Neutrons is a good example. There are also different types of Beta radiation. A positron is also considered as a Beta particle. Roentgen rays are also a form of ionizing radiation. Furthermore there are maaaany types of non ionizing radiation. Neutrinos, myons etc etc. And dont forget about visible light.

That's a really nice video. I looked it with no sound in the bus and understand everything.

Thank you, author!

It is reAlly helpful for me in these exam days ,, thanku

Hi, great video, it is simple and informative, can I use some parts of your video in one of presentations that I will upload online to my students as part of their e-learning due to the corona virus? I will put the URL of your page. Thank you

Good video. Actually a very good video

As a N.B.C. trainer I would like the display just seen. Would have saved me a lot of time in classes. Your demo is top drawer. And why my walls are a foot thick last of least the dry wall has a layer of industrial foil on the side facing the outside. Won't stop it all but increases my chances. Tks

Vry well explained😊👍

Very nice animation thanks sir i understand easily

Thanks for the info :)

Dude, you correctly stated U235 fission produces Krypton & Barium, but your video shows Kr & Br (Bromine). I only hope my doctor doesn’t confuse these two elements if I ever need a Barium (Ba) CT scan.

This video is a great video will help mi in ma cxc

Отличное видео, отвечает на все вопросы о радиации

So owesome this lesson is intersting

Damn the info here is incredible Short,sweet,and on point I love it Just a bit shame that this vital information for chemistry was never and still never touched by My school But The Exam somehow Include this study

3:17 does it always split into those two elements? I would think it would depend on if the nucleus was struck in the center, or off to some degree of off to the side.

Its on my recommendations!

So amazing

That helped so much...

Awesome totally awesome.

Wow so simple thanks

Thank you so much sir

Amazing

Thank u very much.

Nice sir☺

Nice thanks!

"the victim's body shows traces of pure energy"

Great Video but few mistakes , the alpha rays cause more biological damage as they cannot penetrate the body they stay inside the body and cause more damage where as the gamma easily penetrates the body and go to the external environment all cause least damage

Interesting!!

Helo, I dont understand - alpha ray stop paper, ok but paper reflective? or tranform to another energy? maybe heat ? or? thank for reply

Thank you youtube for putting this in my recommendation after my finals

Thankyou!

Yep, I got a case on my hands. Thanks👍🏽.

I really don't understand why people would dislike this video. I bet they're just like "No understand. Science bad. Video bad."

I watched NileRed’s Uranium Glass video and am wondering why some Geiger counters can detect beta particles and gamma rays but not alpha rays since alpha rays are bigger. Does anyone know why?

thanks a lot☺☺☺☺👍👍👍

Thank you

What is amerecem 241 dose it have the same sorce? Its in smoke alarms

Thanks sir

Thanks for info...#

The "fast moving neutron" is not what's likely to cause 235-U to fission. Thermalizing them makes them a lot more effective.

👍👍👍👍👍good bro

For instance in a atomic bomb , what guides the neutrons into splitting the atoms does it just all happen on impact or is there something else?

Nice

2:05 How can beta particle (AKA electron) penetrate my body when thay do not penetrate *air* and because electronic tube and kinescope must be vaccuumiered?

I get knowledge for this video

Pure energy

Everything perfect... Then we got to the "tur-bins"

I am industrial radiographer..using IR 192

Why did you show Br nuclei in the chain reaction? I thought it was Ba nuclei that were produced

You are very hard teaching yarr. Nice

I wonder that I could understand the concept radiation in the video of 4 second .thank u sir

If you shot a specific amount of energy at U-235 will you always expect the fission of Kr and B to occur?

Yeah had to go in to weld a pipe in the rb and there was a primary heat transport pipe 12" with an elbow close to our heads was hot. be surprised that sediment does end up at the bottom of pipes. They wrapped it up in a led blanket.

First question...What cheap alpha beta and gamma radiation ☢ detector would you recommend?

Now I know the reason why lead shield was added to Rutherford's alpha particle scattering experiment.

Thanks... but how impact chain reaction to human body?

Is it necessary to use horse-shoe magnet ?

Isnt there like two genre of beta rays ? Positrone or an electrone

What's confusing is some fission is caused by thermal (slow moving) neutrons that sorta just glom on to certain uranium isotopes. We are always taught that it's always the fast neutrons that crack into, like so many billiard balls, the uranium.
