THE DETERMINATION OF SUBMICROGRAM QUANTITIES OF PLUTONIUM 239
Technical Report
·
OSTI ID:4221295
Plutonium fluoride and lanthanum fluoride are coprecipitated and mounted on a stainless steel dish. The aliquot of solution to be analyzed should not contain more than 1 g of uranium. The smallest amount of plutonium that can be determined is dependent on the background of the counter; this background can be as low as 3 counts per hour (about 6 disintegrations per hour of plutonium) if an alpha -scintillation counter is used. The method has a negative bias of 2.5%. The coefficient of variation, when counting statistics permit, is 2%. (auth)
