Practice for use of a polymethylmethacrylate dosimetry system
1.1 This is a practice for using polymethylmethacrylate (PMMA) dosimetry systems to measure absorbed dose in materials irradiated by photons or electrons in terms of absorbed dose to water. The PMMA dosimetry system is generally used as a routine dosimetry system.
1.2 The PMMA dosimeter is classified as a Type II dosim-eter on the basis of the complex effect of influence quantities (see ISO/ASTM…
