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
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.
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.
@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...
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.
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."
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
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.
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!
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!
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.
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.
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.
