    Abstract

    In the development of techniques for the retrospective assessment of the close absorbed by communities living and working adjacent to the site of a nuclear accident, attention has concentrated on the use Of natural minerals such as quartz and feldspar as dosemeters. These minerals are widely found in household earthenware and almost all types of bricks and concrete. Their main disadvantages are variable and often low sensitivity. and the possibility of a comparatively large natural dose prior to the accident, depending on the age of the building and the type of building material. However, there are Other potential unheated crystalline materials found in the domestic and industrial environment which may also act as retrospective dosemeters, and may be considerably more sensitive. We have Surveyed the thermoluminescent and optically stimulated luminescent (OSL) characteristics of several such chemicals and this paper reports oil the OSL sensitivity, the size of the residual close immediately after manufacture, stability and derived minimum detection limits.
