[en] A dosemeter badge with two TL detectors has been designed for the simultaneous measurement of H_p,(0.07) and H_p(10). The performance of the dosimetry system has been investigated for various X and β ray fields with radiation incidence between 0^o and 75^o. For arbitrary mixtures of the test radiation fields the response to H_p(0.07) varies between 0.57 and 1.62. The response of the dosemeter to H_p(10) ranges between 0.39 and 1.60 for X rays. The thin TL detector has some stability problems which can probably be reduced by optimising the annealing procedure. (Author)
