In an apparatus for measuring facial exposure to radiation, a housing is provided and includes a first recess defined in-part by an end wall. A chip holder is also provided and defines a second recess adapted to carry a thermoluminescent dosimetry chip. The chip holder is positioned in the first recess with the end wall and the first recess cooperating to form a chamber that encapsulates the thermoluminescent dosimetry chip. The apparatus is mountable to an eye protective device, such as a face shield, eyeglasses, or safety glasses to measure the amount of radiation to which the facial area of the wearer is exposed.

[ What is claimed is:] [1.] An apparatus for measuring facial exposure to ionizing radiation, mountable on protective eyewear, comprising:a housing including a first recess defined by an inner perimeter and an end wall;a thermoluminescent dosimetry chip;a plug having an outer perimeter of a shape complimentary to the inner perimeter, and defining a second recess adapted to receive and releasably retain the thermoluminescent dosimetry chip;the plug carrying the thermoluminescent dosimetry chip being slidably received in and abutting the endwall of the first recess, the end wall and the second recess co-operating to define a chamber that encapsulates and protects the thermoluminescent dosimetry chip; andmeans for coupling the housing to an upper brow portion of the protective eyewear such that the thermoluminescent dosimetry chip is positioned between the eyes of the wearer and constitutes a self-contained radiation exposure measurement device thereby enabling the thermoluminescent dosimetry chip to measure the amount of ionizing radiation to which the face and eyes of the wearer are exposed.
