Radioactive Half-life Experiment - Part 1 - Equipment Overview

[MatrixHacker97]

I cant understand a thing... i do my science studies in french

[JeffersonLab]

@MatrixHacker97 Well... it is closed captioned. And, YouTube has a (beta) translation service that will convert the closed captions to French. Give that a try.

[bensonwu8]

I understanded about 1/8 of the talking part teaching part...

[JeffersonLab]

@bensonwu8 That's three half-lives...

[MADJIHAD1942]

I remember using a photo multiplier tube to detect radiation at a science museum when I was like 8. Very cool stuff now that  I know allot more about physics.

[flarn2006]

Half-life experiment? Oh no! Don't open a portal to Xen!

[danictheman]

@flarn2006 LOLWUT?

[SAmmyulito1]

dip a giant marshmallow in liquid nitrogen

[JeffersonLab]

@SAmmyulito1 A little off-topic, don't you think?

[Blacktronics]

@JeffersonLab But a nice idea, i would prefer a rose tho

[JeffersonLab]

@Blacktronics How about a carnation? See "Liquid Nitrogen Experiments: The Carnation".

[Blacktronics]

@JeffersonLab Oh Thanks a lot, did not check throught all of your videos yet, /facepalm at myself there

[Vballgirl0017]

i understood none of that

[JeffersonLab]

@Vballgirl0017 Well, if you can pick one thing in particular, it'll be easier to explain it. There is a 500 character limit in these comments, so I can't really explain everything that was covered in the video in one go.

[AirSofter241]

im confuze

[JeffersonLab]

@AirSofter241 About what?

[AirSofter241]

@JeffersonLab well it kinda sounds like your speaking thaiwanese with science mixed in

[BoomBoomSn1p3r]

While I'm on the subject, would it be possible to bombard a radioactive isotope with something other than a neutron and achieve an effect? (For example, a proton or electron?) Furthermore, what would happen if a neutron was accelerated? Would it achieve nuclear fission to be less stable? (In regards to the entropy it would cause)

[coolsnape]

heck i wouldent even go near the smallest pice of radiation

[JeffersonLab]

@coolsnape It's impossible to avoid radiation. Have you ever eaten a banana? Or drunk a glass of milk? Potassium and calcium both have radioactive isotopes that exist in nature. Eat a banana or drink milk and you're ingesting radioactive material. The calcium gets incorporated into your bones, so those are radioactive as well. Is this something to worry about? Not at all. But, your desire to never go near the smallest piece of radiation can't be fulfilled. It's actually part of you.

[coolsnape]

@JeffersonLab well i know that but i mean if it was a ratioactive icotope or waste i wouldent get close

[JeffersonLab]

@coolsnape Isotopes are just atoms of an element with differing number of neutrons. Some isotopes are radioactive. Some aren't. So, some of the potassium isotopes in a banana are stable. Other isotopes are radioactive.

[coolsnape]

@JeffersonLab well thx for teaching me somthing =D

[sm3xything]

half life, i love that game!.... errrrm *slowly creepys away*

[alfredoowns12]

This is very interesting and I like how ya'll explain everything so smoothly. And I like the guy for some reason, he kinda reminds me of Charly from Lost. All in all great channel keep it up!

[Snakecharmer95]

wow this is very interesting. i can't wait to do chemistry in high school next year or in collage. awesome

[mauritani987654]

@Snakecharmer95 this is more like fysiks.

[Valc0nPr1me]

@Snakecharmer95 It takes QUITE a while for Chem to be this interesting, since they have to teach everybody the simple things first.

[odysseus9672]

Much improved - the presenters are much more natural here. :)

[JeffersonLab]

@odysseus9672 Thanks! We're trying!

[DidntKnowWhatToPut1]

I have spent the past month or so playing with my hand-held Geiger counter. There's nothing more fun then finding a radioactive rock while on a walk aha

[JeffersonLab]

@DidntKnowWhatToPut1 Actually, that is pretty cool.
