Abstract

This paper aims to introduce original data from measurements conducted in Wadi Bin Hammad, region, Jordan. These data highlight the new result of high-radiation dose equivalents found in part of the region, and also recommend further studies. The exposure rates due to terrestrial gamma radiation were measured in cold and hot water in Wadi Bin Hammad cold and hot water springs. The radiation levels were measured using a portable Geiger-Muller counter and an NaI (Tl) detector. The measured absorbed dose rates in air ranged from 15-30 nGyh^-1 in cold and 100 to 2740 nGyh^-1 in hot water spring areas. The maximum high radiation dose was found nearby the principal hot water source. The gamma doses outside this region were around 30 nGyh^-1, which is very low.

Key words: Hot spring, radiation level, Na(TI)detector, absorbed dose rates.
