Bioassay is the preferred individual monitoring technique for radiation workers handling phosphorus‑32 (³²P), a pure beta emitter (β_max = 1.71 MeV) with 14.3 day half‑life. The method standardized at Bioassay Laboratory, Trombay and in use for this purpose includes estimation of ³²P in urine by coprecipitation with ammonium phosphomolybdate followed by gross beta counting. In this study, the feasibility of Cerenkov counting for detection of ³²P in bioassay samples was explored, and the results obtained were compared with the conventional gross beta technique.
