Experimental determination of dose distributions from Cf252 therapeutic sources
Creators
Description
A simple methods of evaluating dose distributions of therapeutic sources on the base of 252Cf, is presented. Radiophotoluminescent alumophosphate glasses of FYD-6 dosemeter of TOSHIBA firm (Japan) have been used as detectors. Dose, produced by γ-radiation of 252Cf, has been measured directly, and neutron radiation has been registered by measuring β-radiation, formed during 31Si decay, which is formed by 31P(n, p)31Si reaction during glass irradiation with fast neutrons β-radiation of 31Si has been registered by Vavilov-Cherenkov radiation, occurring in glass. Thus, it is possible to measure the dose of neutron and γ-radiation of sources simultaneously, disregarding contribution of thermal neutrons (<5%). Methods and applied devices are described, diagrams of radiation weakening are presented. Measuring error is determined. The suggested method is advisable in clinic investigations
