The TLD extremity dosimetry system described herein incorporates the c
omponents necessary for personnel extremity monitoring to meet current
and proposed requirements. Single and dual element TLD dosemeters, ra
nging in thicknesses from 20 to 100 mg.cm(-2), and appropriate filtrat
ion comprise the extremity detectors which are uniquely identified by
bar code labels. A dose algorithm used in conjunction with the dosemet
ers and TLD reader technology are capable of reporting shallow dose H-
p(0.07) from betas, low and high energy photons using any combination
of these dosemeters. Performance tests and results were obtained by th
e Idaho National Engineering Laboratory (INEL) Operational Dosimetry U
nit in the evaluation of a single extremity dosemeter capable of simul
taneously monitoring beta and high energy gamma. Four TL materials and
two filter types were tested in various combinations to Cs-137 photon
s, uranium slab, Sr-90/Y-90, and Tl-204 beta, irradiations. An overvie
w of the current INEL system dosemeter response, linearity, angular de
pendence, residual, and effects of physical damage to the dosemeter we
re tested. The results of these tests, presented here, lead to the pre
liminary conclusion that an extremity dosemeter can be constructed to
monitor beta and high energy gamma radiation simultaneously.
