Phosphonas-32 was used as a tracer to measure the rate of radiation induced exchange of phosphorus in PCl ₃-POCl₃ binary solutions. Ultraviolet and gamma radiation induced sufficient exchange to permit a study of the kinetics of the system, but exchange was not induced by visible light. The amount of phosphorus exchanged was found to obey the equation M = k'bD + k''abD, where a and b are concentrations of PCl₃ and POCl₃, respectively, and D is the gamma or ultraviolet dosage. Values for k gamma / and k gamma '' were found to be (3.19 plus or minus 0.16) x 10^-10 rad^-1 and (4.24 plus or minus 0.31) x 10^-11 g mmole^-1 rad^-1. For gamma rays the ratio k /k was 15 times larger than it was for ultraviolet radiation.
