It sounds like each of you have, although you've worked extensively with isotopes, tracers, [and] radioactive materials, that you've developed a cautious respect for the hazards associated with radiation, Alpha Emitter Studies Using Radioactive Isotopes Yeah. Well, it's sort of in parallel to the alpha emitter studies.

Since the number of protons in the nucleus of an atom determines the element, the loss of an alpha particle actually changes the atom to a different element. For example, polonium-210 is an alpha emitter. During radioactive decay, it loses two protons, and becomes a lead-206 atom, which is stable (i.e., nonradioactive).

So all radioactive isotopes decay by giving off either electrons or positrons? There's also a third type of radioactive emission. After alpha or beta decay, a nucleus is often left in an excited state--that is, with some extra energy. It then "calms down" by releasing this energy in the form of a very high-frequency...

Thus, while extremely high radiation doses may be deposited in the few cells immediately surrounding a source of alpha radiation, regions outside this small irradiated spherical volume are not affected. Table 5-III illustrates this for a 37 KBq (1.0 µCi) source of an alpha emitter of moderate energy.
