Development of a high range TLD dosemeter.
Global Dosimetry Solutions Inc. has developed a high range TLD dosemeter capable of measuring high-energy photon doses to 1 KGy. Additional correction factors have been established for as many as 10 various X ray and beta sources, allowing for high range monitoring of other sources and energies from 500 to 1000 Gy. The product utilizes TLD-100 and TLD-700 chips, available in three different configurations of very small size, and is offered at an economical price. Data analysis is quick, providing results within 24 h in most cases. This report describes the testing completed to support this product, primarily the determination of the supralinearity corrections necessary for doses up to 1 KGy. The test results are considered preliminary due to minimal data points between 0.5 and 1.0 KGy. Additional irradiations are being conducted to establish a more accurate statistical curve at this high dose level. Due to the high dose residual these dosimeters are considered for single use only.
