Abstract:
Demand for accurate and reliable gamma dosimetry in a radiation environment and the unsatisfactory performance of the existing devices has given rise to the need for a better gamma measurement system, capable of operating in a high dose rate environment and withstanding a high total dose. The concept of a new gamma dose measurement device based on the principle of photoconductivity has the potential of filling this void. Preliminary experiments and analyses indicated that the selected dosimeter materials exhibit photoconductivity in a useful range, responsive to changes in gamma dose rate. The initial Pyrex glass dosimeter appeared to suffer radiation damage at the relatively high dose rates employed (up to 0.116 Mega rads/hour). Quartz is now being studied as an alternative material.
