By contrast, there exist two types of radioactive decay processes (gamma decay and internal conversion decay) that do not result in transmutation, but only decrease the energy of an excited nucleus.An apparatus for making radiographic pictures of an object submerged in a liquid comprising a substantially watertight housing having a reduced central section provided with a liquid displacing seal.The object to be irradiated is receivable in the reduced central section adjacent the liquid displacing seal.Unformatted text preview: Radioactive decay For particle decay in a more general context, see Particle decay. Alpha decay is one example type of radioactive decay, in which an atomic nucleus emits an alpha particle, and thereby transforms (or 'decays') into an atom with a mass number 4 less and atomic number 2 less. Radioactive decay is the process by which an atomic nucleus of an unstable atom loses energy by emitting ionizing particles (ionizing radiation).For more information on hazards of various kinds of radiation from decay, see Ionizing radiation. The emission is spontaneous, in that the atom decays without any interaction with another particle from outside the atom (i.e., without a nuclear reaction).
