Abstract

The use of electron paramagnetic resonance spectroscopy to accurately evaluate the absorbed dose to radiation-processed bones (and thus meats) is examined. Additive re-irradiation of the bone produces a reproducible dose response function which can be used to evaluate the initial dose by back-extrapolation. It was found that an exponential fit (vs linear or polynomial) to the data provides improved accuracy of the estimated dose. These data as well as the protocol for the additive dose method are presented.

摘要

研究了使用电子顺磁共振光谱法准确评估辐射处理过的骨头（以及肉类）的吸收剂量。对骨头进行附加再辐照会产生可重复的剂量响应函数，该函数可用于通过反向外推来评估初始剂量。研究发现，对数据进行指数拟合（相对于线性或多项式拟合）可提高估计剂量的准确性。本文展示了这些数据以及附加剂量法的方案。
