摘要：

The results of the first wide-scale application of electron paramagnetic resonance (EPR) with tooth enamel for retrospective dosimetry for permanent residents of Borovskii and Zhukovskii districts (Kaluga region, Russia) are presented. Since these districts have never been radioactively contaminated, their population could be used for comparison studies of the suitability of molars, premolars, canines and incisors for EPR dosimetry purposes. Altogether 136 samples have been investigated. For molars and premolars (103 samples) a linear correlation between the dose absorbed in tooth enamel and the tooth age has been identified. For incisors and canines no such correlation has been found; also, in this case, the doses absorbed in tooth enamel exceeded the dose values for molars and premolars. The data obtained may be connected with the exposure of front teeth to sunlight, which is supported by dedicated EPR experiments with exposure to sunlight and laboratory ultraviolet (UV) radiation. The proposed interpretation and problem areas are discussed.
