Status of the coincidence-counting system used for the metrology of radionuclides, and the standardization of 60Co and 57Co

Creators

Description

A coincidence method, employing a 4π proportional counter (4π(PC)) and NaI(Tl) crystals as detectors, was used for the accurate standardization of stocks of 60Co and 57Co. The experimental arrangement is described in detail. Procedures are given for the adjustment and determination of dead times, resolving times, and time delay between channels. Samples of the standardized solutions were submitted to the Bureau International des Poids et Mesures (BIPM) and the International Atomic Energy Agency (IAEA) for comparison versus measurements from other countries. Other samples were issued for local use
