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.
An extremity dosimeter comprising a solid TL body affixed to a non-luminescent flexible substrate that has integrally associated therewith indicia embodying a machine readable identification code, said substrate including a first layer to which said solid body is affixed and a second layer of equal or greater thickness material.
In combination, an extremity dosimeter and a holder for said dosimeter, said dosimeter comprising a solid TL body affixed to a non-luminescent flexible substrate that has integrally associated therewith indicia embodying a machine readable identification code, and said holder comprising a generally flat and flexible single-use dosimeter pouch including at least one pocket for containing the dosimeter, said pouch including two flexible panels peripherally joined together to form said pocket, at least one of said panels or at least a portion of one of said panels proximate the indicia on said dosimeter being transparent to provide a window through which the indicia may be read from outside said dosimeter pouch, and there being provided means for attaching the dosimeter pouch to a body part.
In combination, an extremity dosimeter and a holder for said dosimeter, said dosimeter comprising a solid TL body affixed to a non-luminescent flexible substrate that has integrally associated therewith indicia embodying a machine readable identification code, and said holder comprising a generally flat and flexible single-use dosimeter pouch including at least one pocket for containing the dosimeter, said pouch including two flexible panels peripherally joined together to form said pocket, both panels being opaque to light, and said holder further comprising a label integral with said pouch, said label including a machine readable code identifying said holder, and there being provided means for attaching the dosimeter pouch to a body part.
In combination, an extremity dosimeter and a carrier for enabling the reading of the extremity dosimeter in a TLD reader designed to read TLD cards containing multiple TL elements at respective read sites, said extremity dosimeter comprising a solid TL body affixed to a non-luminescent flexible substrate that has integrally associated therewith indicia embodying a machine readable identification code, said carrier including at least one slot for receiving said extremity dosimeter and positioning said solid TL body at a selected one of said read sites, and said carrier including on one side thereof a window for said slot through which said identification code can be machine read.
