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.
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.
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.
Alpha, beta, gamma.
Gamma rays have higher penetrating ability compared to alpha and beta particles. Gamma rays can penetrate through most materials, while alpha particles can be stopped by a sheet of paper and beta particles by a few millimeters of aluminum.
Gamma radiation is a type of electromagnetic radiation, whereas alpha and beta radiation are composed of particles. Gamma rays have the shortest wavelength and highest energy, whereas alpha and beta particles are larger and less penetrating. Gamma radiation does not carry an electric charge, while alpha and beta particles do.
Alpha, Beta and Gamma
The three types of radiation given off by radioactive substances are alpha particles, beta particles, and gamma rays. Alpha particles are the least penetrating, beta particles are more penetrating than alpha particles, and gamma rays are the most penetrating and dangerous type of radiation.
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
The correct order is c) Alpha particle, beta particle, gamma ray. Alpha particles have the greatest mass, followed by beta particles, and then gamma rays which have no mass.
Alpha, Beta, Gamma and cosmic are all examples of radiation.Types of radiation could be:Ionizing radiationElectromagnetic radiationInfra red radiation
alpha particles, beta particles, gamma radiation
The three main types of radiation are alpha radiation, beta radiation, and gamma radiation. Alpha radiation consists of alpha particles, beta radiation consists of beta particles, and gamma radiation consists of gamma rays.
The gamma ray is not a particle but is just an electromagnetic wave that transmits energy.
Gamma rays are a type of electromagnetic radiation that have no mass or charge, unlike alpha and beta particles which are charged particles. Gamma rays have higher energy and can penetrate deeper into materials compared to alpha and beta particles. They are also more difficult to shield against due to their high penetrating power.
