Dosimetry Process

For all of the services provided by RDS, thermoluminescent dosimeters (TLD) and associated apparatuses are mailed to and irradiated at requesting institutions. The irradiated TLD are mailed back to RDS where they are read and doses calculated using a well-established protocol with an uncertainty of ≤ 1.5 % (Kirby et al., 1992). Our system is calibrated with TLD standards irradiated at the MD Anderson Accredited Dosimetry Calibration Laboratory. The TLD dose measurements are compared to the institution’s stated dose and a report is issued to the institution for each beam or dose point checked.
