Document Summary
The three types of radiation from radioactive materials are beta, gamma, and alpha. Gamma rays have no charge, so pass through the electric field without deflection. Gamma rays are not particles but rather high-energy photons, which explain their lack of charge. Beta particles (electrons) are attracted to the positive plate of the electric field. Alpha particles have the same composition as a helium nucleus, and so are attracted to the negative plate in the electric field. Each of the following equations represents a radioactive decay process. 1e + ? (cid:2871)(cid:2876)(cid:2877)(cid:2868) e (cid:2869)(cid:2868) + (cid:2871)(cid:2877)(cid:2877)(cid:2868) Nuclear fusion happens when two nuclei with mass numbers lover than 56 merge to produce a new nucleus with greater z, and liberating enormous amount of energy. The sun is powered by the nuclear fusion of hydrogen into helium: 41. Nuclear fission is a nuclear reaction in which the nucleus of a heavy atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons.
