The preparation of radioactive sources with radioactivities of less than 110 kilobecquerels.

Abstract

A description is given of the various radioactive sources prepared in the ANSTO Radioisotope Standards Laboratory and the procedures associated with their preparation. ANSTO is authorised by CSIRO to maintain the Commonwealth standard of activity of radionuclides. Counting sources are required for the standardisation of solutions of radionuclides. Calibration sources are required for equipment used to detect radioactivity such as gamma-ray spectrometers and can be supplied to clients in other organisations. The maximum radioactivity supplied is 110 kBq.
