Abstract: Harshaw6600 is a more widely used thermoluminescent dosimeter system currently in China. A series of parameters is setinside of the system, to calculate the dose data and to ensure the accuracy ofcalculation. The definitions of these parameters are briefly introduced. Its principle of dose calculation is analyzed, and the accuracy of dose calculation isverified. Some suggestions on dose calculation for radiation of low energy ray are provided.

Key words: Thermoluminescent dosimeter, Element correction coefficient, Reader calibration factor, Energy discriminating
