Incompatibility of sensitisation and re-estimation of lithium fluoride thermoluminescent phosphor
Year: 1978
Type: article
Abstract: A technique of useful sensitisation of lithium fluoride has been reported by Mayhugh and Fullerton (1974). This technique differs from that previously described by Cameron and Zimmerman (1965) in that during the anneal at 300 degrees C which follows the high pre-dose, the phosphor is simultaneously exposed to 254 nm ultraviolet light. It is reported that this method removes interfering centres and hence reduces the lowest detectable dose. Sensitisation also has the advantages of improved tissue equivalence and increased range of linearity. It is shown that a disadvantage of both techniques of sensitisation is that for sensitised phosphor, absorbed doses cannot be reestimated by photo-transferred thermoluminescence.
