Californium 252 cf 252
WebCalifornium-252 is a very strong neutron emitter. One microgram releases 170 million neutrons per minute, which presents biological hazards. Cf-252 also decays by energetic alpha emission (half-life 2.65 years, 6.1 MeV). Proper safeguards should be used when handling californium isotopes. Properties WebNov 7, 2016 · UAE environmental regulations call for minimizing exposure to radioactive waste while drilling. In depleted carbonate reservoirs, the low radiation energy, short half-life Californium-252 (Cf-252) neutron source provides a "fit for purpose" replacement to the high radiation energy, long half-life americium-beryllium (Am-Be) neutron source.
