Dosimetric properties of electret ionisation chambers

An integrating electret dosemeter is an analogue of a common ionisation chamber replacing one electrode by an electreto Using such dosemeters in personnel and environmental monitoring the radiation registration sensitivity as a function of kind and energy of radiation as well as of wall material and interelectrode distance is of interest© In the present work these values were determined theoretically and experimentally for incident X- and gamma rays and neutrons for a parallel plate chambero The chamber contains a corona-charged PTPE electret. In order to get high charge stability formation at elevated temperatures was studied.
