This paper presents the evaluation of natural radioactivity and radiological hazards of the
terrestrial naturally occurring radionuclides of^ 226 Ra 226 Ra,^ 232 Th 232 Th and^ 40 K …

The activity levels of 226Ra, 232Th, and 40K in 38 soil samples collected from four areas (Al
Assyah, Buraidah, Al Shamassea, and Al Badayyia) in Qassim (Saudi Arabia) were …

Abstract The 226Ra, 232Th (228Ra), 40K activity concentrations in soil distributed in 67
points belonging to different geological formations in Khammouan, Laos were measured …

The activity and gamma-absorbed dose rate due to the naturally occurring radionuclides in
the terrestrial environment such as 238U, 232Th and 40K were determined in soil and rock …

The effects of the environment on human exposure to radiation from naturally occurring
radioactive elements have been investigated around the world. In the group of natural …

The radioactivity concentration and the natural gamma absorbed dose rates of the terrestrial
radionuclides (226 Ra, 232 Th, and 40 K) have been measured in soil samples collected …

The present study aims to obtain the baseline data on natural and fallout radioactivity and to
evaluate radiation hazards caused by ionizing radiation emitted from 226 Ra, 232 Th, 222 …

Radioactivity concentration of naturally occurring radionuclides, 226Ra and 40K, in soil
samples of Zanjan province, in north-west of Iran and from 21 geographical areas was …

Abstract 226 Ra, 238 U, 232 Th, and 40 K radionuclides have been determined using
gamma-ray spectrometry in soil samples collected from urban areas in the southern …
