EFFECT OF BODY BACK SCATTER ON POCKET DOSIMETERS AND ATOMIC ENERGY COMMISSION-HEALTH AND SAFETY LABORATORY FILM BADGES

摘要

The AEC-HASL film badge is calibrated in free air against a Cobalt-60 standard. In the field the badge is worn on the clothing and in the past, has been exposed most frequently to the gamma radiation of radium.nAn experiment has been performed to ascertain whether a correction for body back scatter is necessary. No such correction is indicated for the AEC-HASL film badge.nA similar experiment has been performed using self-reading pocket dosimeters. No important difference could be found between the response of these instruments to Cobalt-60 or radium gamma;nor between exposure under free air or back scatter conditions.
