✦ Synopsis

We found that inorganic compounds labelled with 32P such as PzSj, PCI3,PSC13,POC13, and H3P04 can be obtained by a newsimplemethod, withgood yieldsand a highspecificactivity. The carrier free 3nP resulting through the nuclear reaction 32S(n,p)32P from elementary sulphur was concentrated on red phosphorus and active carbon. Then, by chemical reactions with phosphorus pentachloride or elementary sulphur, PC13, POCI3, PSC13, and PzS5 labelled with 32P are obtained. Carrier free H332P04 is obtained by desorption of radiophosphorus from active carbon with 2M H N 0 3 at 80'C.

To prepare compounds labelled with3'P for medical, biological, agricultural use, etc. it is necessary to have intermediate inorganic substances such as 32PC1,,
