Thermoluminescence and linear thermal expansion of Mg[Al.sub.2][O.sub.4]

The co-efficient of linear thermal expansion ([α.sub.av]) and dose dependence of thermoluminescence (TL) in Mg[Al.sub.2][O.sub.4](s) were measured. The change in length per unit length was recorded as a function of temperature between room temperature to 1,273 K at a heating rate of 8 K [min.sup.-1]...

Description
Summary:The co-efficient of linear thermal expansion ([α.sub.av]) and dose dependence of thermoluminescence (TL) in Mg[Al.sub.2][O.sub.4](s) were measured. The change in length per unit length was recorded as a function of temperature between room temperature to 1,273 K at a heating rate of 8 K [min.sup.-1], in flowing argon atmosphere. The average of three measurements was quoted as the [α.sub.av] for Mg[Al.sub.2][O.sub.4](s). The linear thermal expansion was measured to an accuracy of ±3 %. The dose dependence of the TL was found to be super linear in the dose range of 0-10 kGy with a k value of 0.503 indicating that the Mg[Al.sub.2][O.sub.4](s) ceramic is ideally suited for the dose estimation of self-irradiated inert matrix fuel in a once through fuel cycle for actinide burning.
