Different types of radiation
Gamma rays are the most extremely energetic known electromagnetic radiation/light/photons. An Alpha particle is an energetic Helium nucleus: 2 protons, 2 neutrons, no electrons. Beta particles are high energy electrons or positions.
a. an alpha particle
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.
Gamma Rays are electromagnetic radiation , just like light is, and it travels the speed of light, 3 x 10^8 m/s . It will always be the fastest because alpha's & beta's are particles with mass and cannot travel the speed of light. The speeds of alpha's & beta's can be different in different situations and do not always have the same speed, like gammas.
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.
Alpha, beta, gamma.
Gamma rays are more penetrating than alpha and beta particles.
Alpha, Beta and Gamma
Alpha, Beta and Gamma. Alpha and beta are both particles, but gamma is in the form of a wave. Gamma can travel the fathest but Alpha is the most dangerous when in contact with your skin
alpha particles, beta particles, gamma radiation
The first three letters of the greek alphabet. If you mean particles, then ... alpha is a helium nucleolus, beta is an electron, and gamma is electromagnetic radiation.
Alpha particles are heavy doubly ionized helium nuclei. Beta particles are nuclear electrons. Gamma are extremely short photons with zero rest mass. Hence obviously, Speed of Gamma>Beta>Alpha.
emission of alpha, beta or gamma particles
Alpha Beta Gamma was created in 1970.
I think you mean : Alpha particles, Beta particles, and Gamma rays.
Alpha rays are positively charged, beta negatively charged and gamma rays is an electromagnetic wave(like light) which has no charge. They have obtained their charges on basis of where they originated from within the atom.
