Comparison of three methods of numerical procedures for ESR dosimetry of human tooth enamel

Appl Radiat Isot. 2005 Feb;62(2):181-5. doi: 10.1016/j.apradiso.2004.08.026.

Abstract

Three numerical methods were employed to examine how gamma ray doses ranging from 100 mGy to 1Gy could be reconstructed using five human molar teeth. For samples above 28 0mGy, the obtained doses are consistent with each other within the errors but slightly larger than actually given doses. Background doses range from 20 to 170 mGy depending on the methods and samples. Further precise studies would be needed to characterize each method, but it would be recommended to apply several methods to check the reliability of the obtained doses.
