CALCULATION OF DOSES FROM EXTERNAL RADIATION. THERMOLUMINESCENCE DOSIMETRY STUDIES

Obiettivo

THIS PROPOSAL WILL PROVIDE MORE INFORMATION ON DOSIMETRY FOR THE PROTECTION OF WORKERS AND THE POPULATION. DEVELOPMENT OF DOSIMETRIC METHODOLOGY FOR A BETTER EVALUATION OF ORGAN DOSES.
Organ doses and effective dose equivalents have been calculated in various situations of practical dosimetric importance. The potential hazard of dosimeter errors for middle energy radiation has been highlighted and recommendations for improved monitoring techniques made.
The calculation of personal dosimeter readings in various fields shows that serious errors can arise in interpreting dosimeter readings, even where the irradiating field is a broad one. The most obvious case is at middle energies around a few hundred keV where the body can partially shield the dosimeter, but the photons are still sufficiently energetic to deposit appreciable doses in the internal organs. Under these conditions area monitoring might prove a better safeguard. The work on the calculation of organ doses due to an infinite plane source under a layer of soil is continuing.
1. CALCULATION OF DOSES FROM EXTERNAL RADIATION.
2. INVESTIGATION OF METHODS FOR IMPROVING THE THERMOLUMINESCENCE PROPERTIES OF THIN DOSIMETERS FOR APPLICATION TO BETA AND LOW ENERGY PHOTON DOSIMETRY.
3. A STUDY INTO THE DEVELOPMENT OF MULTIPLE DOSE RE-ASSESSMENT IN THERMOLUMINESCENT MATERIALS FOR HIGH DOSE MEASUREMENT AND INTO FACTORS AFFECTING THE EFFICIENCY OF BOTH OPTICAL AND THERMAL TRANSFER AND RECOMBINATION PROCESSES IN THESE MATERIALS.
