What are three kinds of radioactivity?

Answer 1

The three major types of radioactivity are: # Alpha Radiation Alpha radiation consists of a stream of positively charged particles, called alpha particles, which have an Atomic Mass of 4 and a charge of +2 (a helium nucleus). When an alpha particle is ejected from a nucleus, the mass number of the nucleus decreases by four units and the atomic number decreases by two units. For example: 23892U -> 42He + 23490Th The helium nucleus is the alpha particle. # Beta Radiation Beta radiation is a stream of electrons, called beta particles. When a beta particle is ejected, a neutron in the nucleus is converted to a proton, so the mass number of the nucleus is unchanged, but the atomic number increases by one unit. For example: 23490 -> 0-1e + 23491Pa The electron is the beta particle. # Gamma Radiation Gamma rays are high-energy photons with a very short wavelength (0.0005 to 0.1 nm). The emission of gamma radiation results from an energy change within the atomic nucleus. Gamma emission changes neither the atomic number nor the atomic mass. Alpha and beta emission are often accompanied by gamma emission, as an excited nucleus drops to a lower and more stable energy state. Alpha, beta, and gamma radiation also accompany induced radioactivity. Radioactive isotopes are prepared in the lab using bombardment reactions to convert a stable nucleus into one which is radioactive. Positron (particle with the same mass as an electron, but a charge of +1 instead of -1) emission isn't observed in natural radioactivity, but it is a common mode of decay in induced radioactivity. Bombardment reactions can be used to produce very heavy elements, including many which don't occur in nature.

Answer 2

There are indeed three kinds of radioactive radiation: alpha, beta and gamma radiation.

More

There are other kinds of radioactivity. Neutrons are given off in some forms of radioactive decay. And there are others.

Answer 3

The 3 types of nuclear radiation are Alpha, Beta and Gamma.

Answer 4

The three main types of radioactive particles are Alpha, Beta, Gamma. However, there are actually five with the inclusion of Positron and Neutron.

Don't forget the Neutrino.

Answer 5

Radioactive materials can be dangerous if someone is exposed to them for long periods of time. Some of these items can be francium, uranium, thorium, plutonium, radium and neptunium.

Answer 6

Alpha, Beta, And Gamma
