You eat the gamma cookie, put the beta cookie in your pocket, and hold the alpha cookie in your hand. Here's why:
Your skin will stop the alpha radiation, so it's safe to hold that cookie in your hand.
Your clothes will stop the beta, so it's safe to put that in your pocket.
And if you're going to have to eat one, you may as well eat the gamma cookie because gamma radiation is so penetrating that you'll get the same does whether you hold it in your hand, put it in your pocket or eat it.
you've sort of missed the point with this one. your right in saying that the alpha wont penetrate the skin, the beta your clothes, and the gamma will penetrate basically everything but its less that you you'd rather eat the gamma cookie because you will get dosed no matter what and more that you do not want to eat the alpha cookie. you see the same reason alpha particles dont penetrate the skin is the same reason they're extremely detrimental when ingested - far more so than gamma. its called specific ionization specific-ionization.
The radioactive element is composed of unstable nuclei that try to reach stability through emitting nuclear radiations as alpha, beta, and gamma nuclear radiations.
The atoms structure is unstable and it emits alpha or beta particles that changes the Atom
An explanation for the use of alpha particles to create other radioactive elements is because it is relatively easy to do. We can concentrate an element that is an alpha emitter in the laboratory, and then use the "alpha bullets" to activate another material. The Curies did this. The alternative is to build a cyclotron, which is a particle accelerator, or a nuclear reactor so the neutron flux can be used to bombard sample. These ideas were a ways down the road when the Curies were conducting their Nobel Prize winning experiments. So these clever individuals isolated materials that were alpha emitters and used them.
Radioactive atoms can give off several different particles. There are three different "types" of radiation, beta, gamma, and alpha. Beta decays which give off electrons/positrons as well as gamma rays (usually). Gamma emmitters are generally meta stable particles that omit a gamma ray in order to stabilize the nuclears, and their are alpha decays which eject a alpha particle (a helium nucleus). On rarer occasions radioactive particles can also be classified as neutron emitters.
A radiation particle consisting of two protons and two neutrons is called an Alpha Particle. Alpha Particles have the same structure as a Helium nucleus. There are three forms of radiation, Alpha (Helium nucleus), Beta (a lone electron) and Gamma (an Electromagnetic wave).
An alpha particle itself is not radioactive, but it is the result of a type of radioactive decay called (obviously) alpha decay. The alpha particle is actually a helium-4 nucleus, and it will eventually pick up a pair of electrons and become an atom of that inert or noble gas.
Alpha
Yes, alpha decay occurs naturally, that is why radioactive material is dangerous, because we can't simply "turn off" the radioactive decay.
In physics, an alpha emitter is a radioactive substance which decays by emitting alpha particles.
Radium, being radioactive, will irradiate and activate some things placed near a sample. The element radium in its "natural" form is an alpha particle emitter, and things that get hit by an alpha particle have a chance of undergoing nuclear transformation. An alpha particle, which is emitted by a 226Ra atom when it decays, is a helium-4 nucleus. It's composed of two protons and two neutrons. This is a "heavy hitter" as regards particulate radiation. It won't travel far, even in air, because it is too massive and it "runs into stuff" in scattering reactions because of its size. But when it reacts with a nucleus, things happen. That's how some materials near a radium source become radioactive.
This phenomenon is rare, non obligatory. For example beryllium irradiated with alpha particles from radium emit neutrons.

An alpha particle
If you mean "alpha radiation", that is the result of certain types of radioactive decay.
I'm pretty sure its alpha.
Thorium-230 is radioactive because it undergoes alpha decay, turning into radium-226 with the release of an alpha particle. This decay process is characteristic of radioactive elements.
