Abstract

A study is made of the corrections that are needed in the evaluation of the annual radiation dose, for use in TL/OSL-dating, via NaI(Tl) field gamma-ray spectrometry (monitoring of K, Th and U), calibrated via voluminous blocks that are simulating the Auger hole measuring conditions. Two cases are considered: the ‘Heidelberg’ granite calibration block, which was found to be ‘quasi-infinite’, and the ‘Oxford’ concrete calibration blocks, for which ‘effective’ concentrations of elements are reported so as to account for their ‘non-infiniteness’. The calculations, via the software package ANGLE, are based on the concept of effective solid angles for Marinelli geometries.
