Both radon and radium concentrations, radon exhalation rate in terms of area and mass, as
well as the annual effective doses were measured in rock samples in Al-Qusair area, Egypt …

The goal of this work is to build up a national database for radon in houses, soil, and water
and to demonstrate health risk due to radon inhalation and to construct radon map in the …

In this study, we used the can technique, containing CR-39, to estimate the radon
concentration from the soils in Karbala city, Karbala governorate, Iraq, radon concentrations …

Radon is a naturally occurring radioactive gas that is known to cause lung cancer.
Therefore, it is essential to measure and determine the concentration of radon in different …

Alpha activity in 20 soil samples of the University of Kerbala (Agricultural College) was
determined using CN-85 detector. Results showed that radon concentrations varied from …

Ar Specific activity of natural radionuclides namely (238U, 232Th, 40K and 235U) and radon
concentrations were measured for soil samples collected from green zone in Al-Najaf city …

In this study, alpha particles in 60 soil samples of the University of Kerbala (Freiha-Sites)
were determined using a CN-85 detector. The results show that the average values of radon …

Measurements of radium concentration, radon exhalation rate (surface and mass exhalation
rates) were made for a number of 168 measurements of soil samples in some towns of the …

Exposure to natural sources of radiation, especially 222Rn and its short-lived daughter
products has become an important issue throughout the world because sustained exposure …

The aim of this research is to implement multilayer perceptron (MLP) and radial basis
function (RBF) artificial neural networks (ANNs) for the estimation of surface and mass radon …
