Radiation doses due to natural radioactivity in Al Hammah hot springs, Jordan

Abstract

Gamma Radiation measurements conducted in Al Hammah hot springs, Jordan are introduced in this paper. These data represent new result of high-radiation dose equivalents found in part of the country measured for the first time. The radiation doses, attributable to terrestrial gamma radiation, were measured using a portable Geiger-Muller counter and an NaI(Tl) detector. The measured absorbed dose rates in air ranged from 70 to 580 nGyh-1 , in hot water spring areas. The maximum high radiation dose was nearby the principal hot water source of the cooling pool. The gamma doses outside the spa region were 30 to 70 nGyh-1 , which is higher than average registered radiation doses rates in Jordan.
