    • Abstract

       

      A rapid method of separation of32P from32Si by hydrofluorisation saves considerable amount of time besides being more efficient in the chemical recovery of phosphorus. Similarly, 4π beta counting of32P activity allows a more accurate estimation of small amounts of this activity. These improvements make it possible to reliably measure amounts of32Si as low as 0·1 dpm present in about 10 tons of water.
