Measurement of gross alpha and beta activity concentration in groundwater of Jordan: groundwater quality, annual effective dose and lifetime risk assessment.

The current study was conducted to measure the activity concentration of the gross alpha and beta in 87 groundwater samples collected from the productive aquifers that constitute a major source of groundwater to evaluate the annual effective dose and the corresponding health impact on the population and to investigate the quality of groundwater in Jordan. The mean activity concentration of gross alpha and beta in groundwater ranges from 0.26 ± 0.

Statistical relationship between activity concentrations of radionuclides Ra, Th, K, and Cs and geological formations in surface soil of Jordan.

An extensive study was conducted to determine the activity concentrations of natural and artificial radionuclides Ra, Th, K, and Cs in soil samples of each governate of Jordan. A total of 370 samples have been measured using a high-purity germanium detector. The activity concentration for Ra, Th, K, and Cs has mean values of 42 ± 3, 23 ± 3, 309 ± 21, and 3.
