The natural radioactivity of ceramic and cement samples collected from Riyadh, Saudi Arabia, was analyzed using a gamma-ray spectrometry system with a high-purity germanium detector. The specific activities of 226Ra, 232Th, and 40K ranged from 45.0

The aim of this project is to create a geochemical database of the Nafud Desert in Zilfi Province, which lies 260 km northwest of Riyadh, capital of Saudi Arabia, and assess its potential as a silicon mine. The area of study was surveyed during Decem
The effect of gamma radiation on the ultrastructure of the cell membranes of red blood cells has been probed using a powerful tool, namely, atomic force microscopy. We used mice erythrocytes as a model. Blood samples withdrawn from mice were gamma-ir

Narghile (hookah, shisha, goza, "water-pipe") smoking has become fashionable worldwide. Its tobacco pastes, known as moassel and jurak, are not standardized and generally contain about 30-50% (sometimes more) tobacco, molasses/juice of sugarcane, var

Radiological impacts of phosphate rocks mining and manufacture could be significant due to the elevated radioactivity contents of the naturally occurring radioactive materials (NORM), such as 238 U series, 232 Th series and 40 K, in some phosphate de

This work aims at studying the accumulation of uranium in sandy soil in an arid region due to the agricultural activities i.e. long time phosphate fertilizer application. Twenty eight soil samples and 14 well water samples were collected from 14 loca

Tobacco contains minute quantities of radioactive isotopes of uranium and thorium series (210Pb, 210Po and 226Ra), which are radioactive carcinogenic. Smoking of tobacco and its products increases the internal intake and radiation dose due to natural

Tobacco and tobacco smoke contain minute amounts of some natural radionuclides such as 210Pb and 210Po, which are carcinogens. Intake of these radionuclides results in an increase of radiation doses to lung cells and tissues. Samples of the most freq
