Abstract
Irradiated egg shells exhibit a paramagnetic center at g = 2.0018. The center is stable up to temperatures of 150 degrees C and against u.v. light. The center concentration as determined by electron paramagneti c resonance spectroscopy increases with absorbed dose. A dose range be tween 3 Gy-10 kGy was examined in which egg shells can serve as a dosi meter. Precision of measurement was found to be better than +/- 10% on a 95% confidence level, for absorbed doses above IO Gy. Egg shells ar e shown to be applicable for retrospective dosimetry after radiation a ccidents.
