Abstract

The radioactivity of different types of building materials used in Jordan, were analyzed using a high purity germanium detector (HPGe). The measured activity concentrations of (²³⁸U, ²³⁵U, ²³²Th, ²²⁶Ra and ⁴⁰K) in Bq.kg^-1were found in ranges (1.7-66.1, 0.02-1.7, 0.3-11, 1.22-65.8 and 8.1-69.4) respectively. The range of radium equivalent activity (R_eq) from a maximum of 87.36 Bq.kg^-1 to a minimum of 3.46 Bq.kg^-1. The mean values of the radium equivalent activities ,Hazard indexes, absorbed dose rate and the annual effective dose were calculated. Our results were analyzed and compared with other results performed in other countries. Results are, with one exception, in accordance with the recommended values of the International Commission on Radiological Protection.
