Abstract
Single crystal chips of Al2O3:C (TLD500) were evaluated and employed for measurements of combined gamma, beta, and cosmic dose-rate. A regenerative dose optically stimulated luminescence (OSL) measurement procedure is described, using the closed source of a Risø reader for irradiation. The reproducibility of these measurements was assessed for both irradiation within the reader, and during field deployment. Combined dose-rate measurements using the chips were corrected for beta attenuation by comparison with independent dose-rate measurements. Dosimeters were buried for up to 3 weeks in the field, providing parallel measurements of in situ combined dose-rate for 79 OSL samples.
