Performance of optically stimulated luminescence Al2O3 dosimeter for low doses of diagnostic energy X-rays

Personal dosimeters measure the radiation dose from exposure to hazardous sources outside the body. The present manuscript evaluates the performance of a commercially available optically stimulated luminescence (OSL) Al2O3 dosimeter using diagnostic energy X-rays. The OSL system satisfies the ANSI N13.11-2001 performance criteria for low dose diagnostic energy X-rays. Non-uniformity of sensitivity, dose linearity, X-ray energy response, and angular performance are all within the criteria of IEC-62387-1(2007).

► We evaluate the performance of a commercial optically stimulated luminescence dosimeter using low doses of diagnostic energy X-rays. ► OSL system satisfies the ANSI N13.11-2001 performance criteria for low dose diagnostic energy X-rays. ► Non-uniformity of sensitivity, dose linearity, X-ray energy response, and angular performance are all within the criteria of IEC-62387-1(2007). ► Results of this study show that OSL dosimeters may be useful for extremity dosimetry for radiation workers and patients exposed to diagnostic X-rays.
