Abstract

The potentialities of optically stimulated luminescence (OSL) for personal dosimetry of ionising radiation have stimulated the search for new synthetic materials with good dosimetric properties. The sensitivity of two new OSL materials KMgF₃ and NaMgF₃ doped with Ce³⁺ ions has been evaluated and found to be of the same order of magnitude as that of Al₂O₃:C. Several other characteristics have also been investigated. Promising results for KMgF₃:Ce are the high sensitivity and the low fading. However, this material suffers from a high self-dose due to the presence of ⁴⁰K. NaMgF₃:Ce is sensitive as well but shows strong fading. Interesting information on the mechanism has been obtained by correlating the signals of OSL and TL. Furthermore, the different bleachabilities under blue LED illumination of the strongly overlapping glow peaks allowed the extraction of one single peak for KMgF₃:Ce³⁺. The results demonstrate new possibilities offered by the combination of TL and 0SL.
