Document Summary

Isotope - same proton, diff number of neutrons. Radioisotopes - they will decay energy in the form of radiation. Ex: carbon 13 and 14 are radioisotopes. Carbon-14 = 6p, 8n, atomic # 14: types of radiation and its energy, alpha radiation. Nuclear helium (he) which has 2 p+ and no. Stopped by paper since it is heavy and big. Can"t travel around bc will be stopped by air molecules short distance travel. If introduced into body, will cause local damage to cells it bumps into. Can be positive or negative, but most time it is negative. Gives a (cid:1445)wave(cid:1446) something concerning waves. Nature is much less (? idk what that means) When they travel they behave as particles and a wave. Not very high energy and thus can be blocked by aluminum or glass, but penetrates paper involves an electron being released (e: gamma radiation. High energy high frequency, short wavelengths.
