Method for determining the temperature of a thermoluminescence element being heated for thermoluminescence dosimetry

摘要

A method and apparatus for measuring radiation doses based upon thermoluminescence which occurs when a thermoluminescence element is heated by a heat source after having been exposed to radiation. A heat energy sensor is provided for the heat source for detecting the heat energy output from the heat source toward the element. Based on the detected heat energy, the temperature of the element is calculated. The calculated temperature is used to determined if remedial action is necessary. For instance, the calculated temperature may be compared with a predetermined optimum heating temperature. If the calculated temperature deviates from the predetermined optimum heating temperature, responsive action is taken. An increase rate of the calculated temperature may also be calculated. The calculated increase rate would be compared with a predetermined heating rate. The heating device would increase its heat energy output from it if the calculated increase rate is lower than the predetermined heating rate and decreasing the heat energy if the calculated increase rate is higher than the predetermined heating rate.
