ESR剂量学可用于估算一般人群以及核应急中职业工作者的外照射剂量。从与JCO临界事故相关的两名暴露工人(A和B)中拔出三颗牙齿。将牙釉质与其他牙齿部分仔细分离,并进行ESR剂量测定。按~(60)Co γ射线剂量估算:A工人右上第8颗牙颊侧和舌侧分别为11.8 ± 3.6和12.0 ± 3.6戈伊;对于工人B,在右上侧的第四牙齿和左上侧的第五牙齿的颊侧和舌侧,分别为11.3 +/- 3.4和10.8 +/- 3.3戈伊,11.7 +/- 3.5和11.4 +/- 3.4戈伊。发现估计剂量相似,不依赖于牙齿位置,无论是每颗牙齿的颊侧还是舌侧。
ESR dosimetry is useful to estimate the external dose for the general population as well as for occupational workers in a nuclear emergency. Three teeth were extracted from two exposed workers (A and B) related to the JCO criticality accident. Tooth enamel was carefully separated from other tooth parts and subjected to ESR dosimetry. Doses equivalent to the gamma-ray dose of 60Co were estimated as follows: for worker A, the buccal and lingual sides of the eighth tooth in the upper right side, 11.8 +/- 3.6 and 12.0 +/- 3.6 Gy, respectively; for worker B, the buccal and lingual sides of the fourth tooth in the upper right side and the fifth tooth in the upper left side, 11.3 +/- 3.4 and 10.8 +/- 3.3 Gy, 11.7 +/- 3.5 and 11.4 +/- 3.4 Gy, respectively. The estimated doses were found to be similar and not dependent on the tooth positions, whether the buccal or lingual sides in each tooth.
