[Comparison of absorbed doses from cobalt irradiation sources].

Abstract

A comparison of absorbed doses from medical cobalt beams was performed by means of thermoluminescent dosimeters at all radiotherapeutic workplaces in Czechoslovakia. At most workplaces (58%) the deviation from the reference primary etalon placed at the Institute of Radiation Dosimetry of the Czechoslovak Academy of Sciences was below 3%. Neither of the workplaces exhibited deviation higher than 5%, indicating a good level of clinical dosimetry.
