0.8 mm of plastic will absorb all emissions. additional shielding. Zinc has been proposed as a "salting" material for nuclear weapons. A jacket of isotopically enriched 64 Zn, irradiated by the intense high-energy neutron flux from an exploding thermonuclear weapon , would transmute into the radioactive isotope 65 Zn with a half-life of 244 days and produce approximately 1.115 MeV [2] of gamma radiation , significantly increasing the radioactivity of the weapon's fallout for several years. Zinc-65 atom is a zinc atom in which the nucleus contains 35 neutrons. It has a half-life of 244 days, decaying by emission of a positron (beta(+) decay), and is the most abundant and stable of the 25 known radioisotopes of zinc.

Zinc-65 can be observed in these samples without chemical separations The decay scheme is illustrated in fig. 5. About 45 O/o of the decay proceeds via electron capture (EC) to an excited state of the daughter nucleus Cues. This excit- ed state of Cues is deexcited by rapid emission of a gamma ray. About 53 010 of the decay of Zne5 proceeds directly to the ground state of Cus5 by EC. Isotopic turnover, again with 65 Zn, is an index.

Zn-65 decays to the Cu-65 stable isotope via electron capture and β+ emission ( 0.330 MeV) and also to an excited state of Cu-65, which emits gamma radiation The Element Zinc - Known Isotopes.
