Abstract Radon, the heaviest among noble gases in periodic table of element is a radioactive nuclide that naturally available rocks, soil and water. It has become subject many research efforts recent years due to its leading role causing cancer. In this study, total 68 groundwater samples were collected assayed using alpha spectrometry with RAD7 radon detector RAD-H 2 O accessories manufactured...

background: radon is one of the most important radioactive elements which is released by natural decay of available uranium and radium in the ground. the presence of radon gas is common, wherever those faults are located there. radon concentration of various drinking water resources of bam villages; located near bam fault; was measured. materials and methods: this cross-sectional study was cond...

Background & Aims: Human beings are constantly exposed to different radiations that have always been recognized as a health hazard. Radon -222 and its daughter products are major sources of natural radiations and a significant total inhalation dose is related to them. Hence, the measurement of radon activity in the environment has gained an increasing importance. In this study, with the measure...

The presence of radon in drinking water causes health risks associated with exposure from both inhalation and ingestion. Since the studies show that faults near the water resources have a critical effect on the concentration of radon, Kouhbanan active fault zone, to find water resources  with high radon concentration was chosen for the following investigation. Water samples were taken from all ...

Usually, phosphate deposits contain 238U and 232Th in addition to their decay products. Due to their different pathways in the environment, the 238U/232Th activity concentration ratio usually found to be greater than unity in phosphate sediments. The presence of these radionuclides creates a potential need to control exposure of workers in the mining and processing activities of the phosphate m...

Global genome nucleotide excision repair removes DNA damage from transcriptionally silent regions of the genome. Relatively little is known about the molecular events that initiate and regulate this process in the context of chromatin. We've shown that, in response to UV radiation-induced DNA damage, increased histone H3 acetylation at lysine 9 and 14 correlates with changes in chromatin struct...
