Abstract: System and method for extremity dosimetry, that emables the maintenance of a chain of custody from dosimeter issuance to dosimeter read and further through multiple reuses of the dosimeter, are uniquely characterized by a reusable extremity dosimeter comprising a solid thermoluminescent (TL) body affixed as by bonding to a non-luminescent substrate that has integrally associated therewith indicia embodying a machine readable identification code. A preferred holder for the extremity dosimeter comprises a generally flat and flexible pouch that may be disposable, the dosimeter pouch including at least one pocket for containing the extremity dosimeter. Provision is made for attaching the dosimeter pouch to the body of a user at a specified extremity location such as a finger, wrist, toe, ankle, elbow, knee, forehead, etc. Also disclosed is a carrier for enabling the reading of the extremity dosimeters in TLD readers designed to read TLD cards containing multiple TL elements.

Abstract: A TLD dosimeter and method of making same, characterized by assembling a solid body of TL material on a non-luminescent substrate with a non-luminescent liquid adhesive interposed between juxtaposed parallel surfaces of the TL body and substrate, and heating the assembly to cure the liquid adhesive thereby to bond the TL body to the substrate. The liquid adhesive is a polyimide. For bonding the solid body to a film substrate such as an aromatic polyimide film, the TL body and film substrate are pressed together during heating and the heating step preferably involves baking the assembly at a high temperature.

Abstract: An improved dosimeter characterized by a filter construction which gives rise to improved angular independence of delivered dose. Also disclosed is an improved tamper-proof holder for a TLD card, and the holder also desirably provides a dirt and moisture resistant environment for the TLD card.
