Abstract
The properties of a number of thermoluminescence (TL) phosphors are reviewed, and the suitability of the phosphors for measurement of Ü3-rays at archaeological sites is discussed. The energy dependence of their response relative to quartz is considered in some detail. Two phosphors, Al<sub>2</sub>O<sub>3</sub>: Si, Na and Mg<sub>2</sub>SiO<sub>4</sub>: Tb, have a response that is almost equivalent to that of quartz. Some problems related to field measurements by means of CaSO<sub>4</sub>: Dy are outlined, and a comparison of CaSO<sub>4</sub>:Dy with Al<sub>2</sub>O, in an irradiation unit based on the U bearing rock luiavrite is described. -- AATA
