Description/Abstract:
THE URINE SAMPLE IS ASHED WITH NITRIC ACID; PLUTONIUM IS COPRECIPITATE D WITH BISMUTH PHOSPHATE, DISSOLVED IN HYDROCHLORIC ACID AND THEN COPR ECIPITATED WITH LANTHANUM FLUORIDE. THE LANTHANUM FLUORIDE PRECIPITATE IS SLURRIED ON A STAINLESS STELL PLATE AND COUNTED FOR ALPHA ACTIVITY WITH A LOW-BACKGROUND PROPORTIONAL COUNTER. QUANTITIES OF THE ORDER O F 2 D/M OR 2 X 10 -11G OF PLUTONIUM CAN BE DETERMINED BY THIS METHOD. THE TOLERANCE FOR PLUTONIUM IN URINE GIVEN IN THE LASL " OFFICIAL MONI TORING HANDBOOK " IS 7 D/M/24 HOUR SAMPLE. SAMPLES ARE RECHECKED IF TH E RESULTS ARE 2 D/M/24 HOUR SAMPLE OR HIGHER.
