Analytical Methods For THE DETERMINATION OF CAESIUM -I37, STRONTIUM-89 AND-90 IN MILK, VEGETATION, ORGANIC ION EXCHANGE RESINS, SEAWEED AND FISH FLESH, AND STRONTIUM -89 AND -90 IN BONE

摘要

Radio-strontium and caesium are co-precipitated on added carriers: After radio-chemical purification the /3-activities due to strontium-89 and caesium-137 are measured. Yirtrium-90 is allowed to grow in, it is separated and the activity measured to determine the strontium-90 content.
