Polymer electret dosimetry Chang, Charles
The work reported in this thesis investigates the possible use of thin film teflon electrets as X-ray dosimeters. Electrets were prepared by corona- and breakdown field-charging and found to exhibit a number of properties that would render them suitable for personnel dosimetry. The stability of the residual electret charge as a function of environment was also studied and it was found that hot, humid or unshielded conditions led to rapid charge decay.
