The Red Sea is a deep semi-enclosed and narrow basin connected to the Indian Ocean by a narrow sill in the south and to the Suez Canal in the north. Oil industries in the Gulf of Suez, phosphate ore mining activities in Safaga-Quseir region and intensified navigation activities are non-nuclear pollution sources that could have serious radiological impacts on the marine environment and the coast...

et al. (2) present a long, continuous, highresolution climate record extracted from a calcite vein in Devils Hole, Nevada. If their dating is accurate, the record appears to contradict the Milankovitch hypothesis (3). Dating of subsamples of the vein was done with the use of well-established principles of 230Th dating (4) and with recently developed techniques for precise measurement of 230Th a...

The ambient background activity of gamma radiation was measured in the nearby village Meghavath Thanda, surroundings upcoming uranium mineralized site, with active and passive methods. estimated average absorbed dose ranging f from 1818 to 2296 µGy.y−1 an 2105 ± 142 µGy.y−1. radioactive elemental analysis collected soil samples area shows that 238U 232Th is higher than global associated index p...

Introduction Natural and artificial radionuclides are the main sources of human radiation exposure. These radionuclides, which are present in the environment, can be dissolved into water. Evidence suggests that radionuclides being entered the human body through drinking or hot spring water can be harmful for human health. Materials and Methods In this study,10 samples were collected from ground...

Background: Natural background radiation of a particular region is one of the distinctive factors defining the status of environment. Eloor Island is an industrial area in Ernakulum District of the state of Kerala, India. The indoor and outdoor gamma level measurements have been carried out for the region for evaluating the annual effective dose to the population residing in this area. Mate...

the activity concentrations of 226ra, 232th, 40k and 137cs in water and sediment samples from hot springs of mahallat and  soil samples from their neighboring environs  have been determined using two high resolution high purity germanium (hpge) detectors with relative efficiencies 38.5% and 55%. the activity concentrations of 226ra, 232th, 40k and 137cs in sediment samples from hot spring donbe...
