RADIATION INDUCED ULTRA-VIOLET ABSORPTION IN METHYL METHACRYLATE AS METHOD OF DOSIMETRY

摘要

Most current methods of radiation dosimetry are very limited in range and become useless after relatively low integrated dosages; i.e. 108 to ergs gm.-1 (C). Hence, the dosimetry problem becomes quite significant when using the higher dose levels and integrated dosages which are needed to simulate the radiation environments of high performance nuclear systems. This technical note summerizes a series of experiments concerned with the development of an accurate method of dosimetry for measuring the dosages encountered when radiation effects are studied at higher levels. The method .investigated utilizes the radiation induced ultra-violet absorption in methyl methacrylate for correlation with total dosages.
