TYPE TESTING OF AN EXTREMITY FINGER STALL DOSEMETER BASED ON HARSHAW TLD EXTRAD™ TECHNOLOGY

摘要

A new type of extremity dosemeter, which incorporates the Harshaw TLD EXTRAD™ dosemeter element into a PVC finger stall, has been developed. The dosemeter uses high-sensitivity lithium fluoride, ~7LiF:Mg,Cu,P (TLD-700H) in a thin 7 mg cm~(-2) layer, with alternative coverings of PVC at 10 mg cm~(-2) and aluminised polyester at 3.2 mg cm~(-2). Results are presented of the type testing of both versions of the finger stall dosemeter against published standards.
