OSTI ID:4823316
A method of extending the usable range of AgPO/sub 3/ glass rod dosimeters by a post irradiation heat treatment was investigated. It was found that heating rods at 325 deg C for one hour clarified most of the radiation- induced darkening but did not greatly erase the fluorescent centers. Removal of the darkening allowed more efficient fluorometer readings to be made on rods exposed to more than 10/sup 5/ r. The net result was an extension of the useful range of the dosimeter by a factor of 25. The extension has a definite application in the glass dosimetry program. There had previously existed a region between the ranges of the AgPO/sub 3/ glass system and the cobalt glass system in which doses could not be adequately measured. The described clarification technique removes the uncertainty of dose measurements in this region. (auth)
