  • he'll be fine he took 2 doses of radX in the morning

  • Thorium look like the "yellow cake" !

  • can you bring one of those to school ? 0.o

  • Fallout 1

  • well daniel humans resist up to about 1000 counts a second so thats wgen ur fucked

  • I'd love to have the last name Geiger

  • @cl25cooldude not if you are the one handling it in a radiation field...

  • please watch my homemade geiger counter

  • just pointing out that as gamma is tiny, the momentum it buids up means that the damage it does is minimal, due to the short period of time in the body, as alpha is so biog and beta travels so fast, the momentum is huge, all three are dangerous, but gamma is the least dangerous of the three, even though it can penetrate skin and flesh. The nutrinos mentioned in the video dont actually affect matter at all

  • So how many counts does it take before things get risky?

  • this is my prof

    and our exam is in two days

    :)

  • @eternalfelicity lucky!

  • Test mayonnaise and pepto bismol with your geiger counter!!!! you will be shocked!

  • @ggabe005 Test a bunch of bananas as well.

  • What's the name of this class? BTW if Stephen didn't get laid after this class, He did his great grandfather a disservice. I agree with Ryan2588 a really great Prof.

  • @Tictocdoc This class is called Chemistry 1000

  • 6 people heard click click clickity and didn't run their asses out of there

  • I just wish he would have explained why that level of radiation (coming from those bottles) was not harmful, and just how much does it take to become harmful.

  • @ElricWinter The reason why gamma radiation is not harmful to us is because gamma radiation has so much energy that it just passes right through us. As for alpha & beta radiation, they have significantly less energy(B>A) & thus can be stopped easily. When alpha particles come into contact with us, they get stopped inside our bodies & thus can never get out of our bodies. During the absorbing process, alpha radiation will break chemical bonds=tissue damage & not too mention the long term effects.

  • @Alien595 Gamma isn't harmful? Its the most harmful type of radiation there is. Alpha is absorbed mostly by the upper (dead) layer of skin cells and is most damaging if you ingest or inhale material that emits alpha radiation. Gamma can go right through your skin and break the bonds making up your DNA, causing genetic mutations. Enough mutations and you have cancer.

  • @echaaaa I think what he meant to say was that alpha particles have a much higher weighting factor when calculating the dose equivalent for each particular kind of radiation. You would need about 20 gamma-radiation photons to match the dose of radiation given by a single alpha particle. Alpha particles have a much higher ionising potential than gamma-rays. It's just that gamma-rays can are less prone to destabilisation that make them more lethal than alpha particles, particularly at a distance.

  • anybody know the best price on were I can buy a geiger counter please?

  • @MjrDario Anywhere between $70-$7000, lol! You can probably get a pretty good one for $200 like the one in the video. An even better one around $400, but a really good professional one is about $800-$900. And so on...

  • @GUARDIANtrooper ok thanks :)

  • Pretty cool video!

  • In the future we'll all probably have to have one of these.

  • Comment removed

  • I like Geiger counters. I like this video.

  • I love how he shakes his hand again at the end of the video, and Stephan Geiger wipes his hands on his jeans!!! 8:11

  • Really good Prof! 

  • i want to shake this hand to .

  • "it's just so cool" HAHAHA

  • I know what I want to do when I get to college. Nuclear Science. :D

  • 7m11s: don't hold it so close to your testicles!

  • Wow. I understands this professor's amazement. His great-grandfather played a pivotal role in understanding how to measure alpha, beta and gamma nucleic activity.

  • SHAVE HIM A ball spot give him a mustache and glasses

  • Where the hell are awesome professors like him? Everyone in my college is boring as hell.

  • this is very interesting

  • I don't know your standing next to the great grandson of a famous man. I would be in aw. I would say, "Your great-grandfather was great man, he invented a useful item."

  • i wish i had a geiger counter

  • @pibbification

    just look for one on e-bay thats how i got mine.

  • is that yellow cake uranium

  • Awesome video! I rarely sit through long videos on YouTube, but this one was very good.

  • Awesome demonstration.

  • What are the materials used in the test?

  • I thought it was when it started beeping at you, you should gtfo.

  • nah if it's 800+ r/h pointing to you may as well pull a gun out and shoot your self cause your fucked

  • Is there anything cheaper than uranyl nitrate that can react noticeably with a geiger counter?

    $595 is quite a lot for 25 grams. :o

  • nice and thanks for uploading such an interseting and helping video

  • Anal

  • this was great really helped with my a level revsion =D

  • of course he did!

  • I wonder if the kid passed the class?

  • That was really quite interesting!

  • Yea. Geiger was a great man.

  • Not only Geiger

    The real name of the counter is Geiger-Müller-Counter they always leave out the poor Mr.Müller :(

  • geiger is funer to say (yes I misspelled, what of it!?)

  • I figured at the least this was not the Universoty of Michigan !

  • Gotta love them physics.

  • And Chem too!

  • where is this ?

  • Carleton University in Ottawa, Canada. I'm in his class this semester, he's a great proffesor!

  • if they made one that could be built into a watch or something it would be useful for locating hidden nuclear threats

  • They have a pocket G-counter.

    Look on United Nuclear . com for the UNDX-1 Pocket Geiger Counter

  • Hey, I know this Geiger.

  • You do? ....Who are you?

  • Seriously it's overrated.

  • Cool.  I wish I was related to Geiger...

  • Part Of The Geiger Family Lucky Bastard

  • how expensive would you say his geiger counter is?

  • in Ukraine near Zone or Kiev you can buy it for even less than 75$, professional electric Geiger counter costs about 100-200

  • Really? Are they any good? Have you been to the zone?

  • yes, ive been there twice so ive got some experience with this device. I didnt rly buy this cause we borowed them from the tour office but ive seen them in shops or marketplaces

  • really easy to build!

  • This video makes me want to drop kick babies. Lol, not really.

  • theres geiger counter in cod 4 too, I kept dying just wanting to listen to the clickety sound xD

  • 250 rads, what the hell is in there

  • @umahuma4

    1000 CPM (counts per minute) are approximately 1 mrem. 100 mrem are the usual background radiation in a year. So 250 CPM are 0.25 mrem or about 1/400th of the average annual radiation.

  • When those Geiger counters go "click click clickety", you better get your ass outta there! XD

  • Also, pop some rad-away just for good measure.

  • actually its run your ass outta there

  • and Tick Tick Tickety

  • means get your ass out of the and pop some Rad Away for good Measure

  • exactly lol

  • Fallout 3

  • It is cool to have a Uranium ore that requires special licensing from the Nuclear Regulatory Commission.

  • anyone else reminded of Half-Life or Half-Life 2?

  • lol yeah, and fallout 3

  • i love fallout 3

  • I love Fallout 3 too.........lol.

  • I hear it crackle all too much in that game

  • i always love the sound of geiger counters

  • lol me too

  • @cj25cooldude i hated it bc it ment you will die if u stay there too long hahaha

  • @cj25cooldude me to!

  • I have many ores and chemicals of Uranium and Thorium. I have ~5-6 grams of pure U-238 Metal (Depleted Uranium). I have other isotopes and ores, even Ekanite, a Thorium-based gemstone, and it's faceted too! This is awesome stuff... U-238 will give an extremely high reading. My Geiger Counter is digital but instead measures in µSv (Micro-Sieverts). I experiment all the time with ionizing radiation. Be careful. Use lead shielding and a respirator! This is an awesome video! 10+! Science RULES!

  • Uranium tablets in a bottle?

    I need to find that somewhere.

    And I wish he would explain the SI unit of measurement for radiation (sieverts).

  • Man, I wish every prof. was like this guy! He's the man.

  • Its like off half life

  • No... Half Life is like off this.

  • lol wow the game and this are soooo different but yes half life is like off this

  • I'm getting one to add to my survival kit. Man, there's people that look JUST like the combine from HL2! Search for "G20 police night time" or something to that effect. Creepy shit, brah!

  • i am related to god

  • my goodness this is amazing this guy is amazing GOOD JOB WITH THE VIDEO AND HAVE FUN WITH U-238

  • i cant express how much i love this video

    i think i've watched it like 34029380293845 times

  • same here

    i wonder what model geiger counter he is using

  • my friend is related to the guy who invented the geiger counter

  • In response to panzerkampfwagen123...he is Canadian! From Carleton!

    Never had a better University professor. He's a legend amongst science students for a reason.

  • I am moving to Canada. :)

  • Yes there is a likeness :)

    Thanks for this video, makes everything really clear for students. Good sense of humour helps also :)

  • That could be uefull, on my fysiks repport, Thanks!

  • This is an absolutely wonderful demonstration of the mechanics of a Geiger counter. 5 stars! Brilliant!

  • Avesome!

  • Very Cool. :-)

  • Yeah i have a Geiger COunter and not to Mention some Radiaoctive Ores

  • Thats really an ignorant question. You should know by now that we are all exposed by radiation from the earth and from Space. You will have to be exposed to concentrated amounts of radiation within a year to have cancer.

  • I am just scared by the Radioactivity it was not an insul or something bad.

  • Well i didn't insult you, i just ment about the question. If you study physics and biology you will know that we are all in a radiaoctive zone other way or another, the people in ireland breath Radon gas all day and it also has an effect on some of the people during there life time, although its harmless if you don't expose yourself 24/7 the whole time in the same area.

  • So that's not dangerous to have Radioactive ores ?

  • If they are stored properly and not held in your pocket for 24 hours. Over all its safe if handled with care, exposure doesn't matter more then it going into your mouth and swallowing bits of particles.

  • Ok Thank's

  • the geiger counter makes the coolest noises
