A high-precision, tissue-equivalent dosimeter for nuclear accident and radiation oncology applications based on optically stimulated luminescence (OSL) in Al2O3 : C

摘要

Injection molding is an important industrial technique for producing large quantities of' identical polymer and polymer composite parts. Although alumina of any kind is abrasive and damaging to the steel molds, a technique was developed that reduces both the mold abrasion and the effective atomic number of the composite polymer dosimeter [Miller, S. 1996a. U.S. Patent No. 5,567,948, issued 22 October 1996; Miller, S. 1996h. U.S. Patent No. 5,569,927, issued 29 October 1996; Miller, S. 1998. U.S. Patent No. 5,731,590, issued 24 March 1998.]. Radiation oncology dose measurement applications would benefit frorn a large unilorm batch of high-precision dosirneters (< 2%, 1 sigma measurement precision). This new, high-precision dosimeter Would eliminate the need to calibrate each closimeter individually, as is currently the case with the thermolurninescence dosimeter measurements performed by the radiation oncology community.
