Preliminary Report on Radiation-Induced Thermoluminescence in Climax Stock Quartz Monzonite

摘要

An examination has been made of the feasibility of using thermoluminescence (TL) for the self-dosimetry of the rock surrounding a canister of nuclear waste. The rock investigated was quartz monzonite from the Climax Stock, a granite intrusive at the Nevada Test Site. Samples of the rock were irradiated by exp 60 Co to doses of 10 exp 3 to 10 exp 9 rads, then ground to a fine powder and read for TL response at a heating rate of 1 exp 0 C per second. Effects of total dose, thermal history after irradiation, grinding to a powder after irradiation, mineral composition, and powder grain size were investigated. All were found to be important, but with care, the use of TL in this manner appears promising. (ERA citation 07:057500)
