• The concept of effective dose equivalent was introduced as a primary limit in the ICRP 26. It was proposed that deep dose equivalent index could be evaluated as a secondary limit for external dose limitation system.A thermoluminescent dosimeter (TLD badge) using Li2B4O7(Cu) elements has been developed to measure deep dose equivalent index for photon depending on this dose limitation system. Radiation characteristics were studied using this TLD badge and a phantom. The results were obtained as follows, 1) Deep dose equivalent index was able to be measured with the accuracy of 20% by 7Li211B4O7(Cu) element under 1, 000mg/cm2 filter.2) In the condition of anterior irradiation, the ratios of effective dose equivalent to deep dose equivalent index were 0.65, 0.76 and 0.85 for photon energy of 60, 100, 662keV respectively.
