Beta Film Monitoring Procedure

It is the purpose of this work to reexamine our beta film monitoring procedure to determine its validity. In the current procedure we assume that film darkening is directly proportional to beta exposure. Based on this assumption, it is general practice to measure the beta dose by subtracting the density due to gamma exposure from the beta plus gamma density read on the open window portion of the film, using the difference to read off the dose on the beta calibration curve. Dental film packets were exposed to beta radiation, from uranium metal in contact, for known periods of time ranging from one to sixteen hours. The plot of density versus beta exposure was found not to be a straight line. This is especially in evidence in the region above 900 mrep. An experiment was devised to determine the error involved in treating film darkening as a linear function of beta exposure.
