Abstract
Precipitated CaCO{sub 3} in the presence of vitamin C has been investigated as an ESR dosimeter. {gamma}-ray irradiation produced a sharp electron spin resonance (ESR) signal with a linewidth (0.015 mT) with high thermal stability. Required microwave power (0.02 mW) and magnetic field modulation (0.02 mT) for ESR measurement were about 250 and 30 times lower than those of DL-{alpha}-alanine, respectively. The lower detection limit was reduced from {approx}3 Gy for a commercial alanine dosimeter to {approx}20 mGy for {gamma}-rays for this material.
