Abstract
The effect of dosimeter placement on personnel monitoring was discussed. The ICRU sphere phantom was compared with anthropomorphic phantoms for dosimetry testing. Dosimeter design considerations and personnel dosimeter angular response were discussed. The use of multiple dosimeters and design factors for multiple dosimeter applications were considered. Examples of existing dosimeter designs which were reviewed included photographic film dosimeters, photosensitive glass dosimeters, spherical thermoluminescent dosimeters, and neutron thermoluminescent dosimeters. Dosimeter angular misalignment and body contour effects were discussed. The dosimeter wearing habits of personnel required to use dosimeters at the worksite were examined. At three large institutions, dosimeter locations and angular orientations were noted. Lack of consistent locations on or angular orientations of dosimeters to the wearer's body indicated the difficulty in the practical implementation of personnel dosimeters having an angular response rather than an isotropic response. Dosimeters which use a penetrating effective dose equivalent response should have an adequate means of mounting the dosimeter to assure the required dosimeter orientation to the body under a wide range of conditions. The goal of dosimeter placement on the person should be to avoid under and over estimation of an individual's effective dose equivalent and to minimize the number of dosimeters required on an individual.
