Is Phosphorus 32 natural or synthetic?
Phosphorus 32 (P-32) is the phosphorus isotope whose nucleus consists of 15 protons and 17 neutrons. It disintegrates by emitting a β- (1.71 MeV) particle in 32S with a half-life of 14.263 days. It is an artificial radioactive substance obtained by neutron bombardment of stable phosphorus.
