“…The minimum, maximum and average value of AEDE for Besant Nagar beach sands are 13±4 µSv.y -1 , 26±6 µSv.y -1 and 18±5 µSv.y -1 respectively. The annual effective dose equivalent values obtained for other Indian coastal regions are: 2360 µSv.y -1 in Chhatrapur beach of Orissa [12], 120 µSv.y -1 in Andhra coast [13] and 507 µSv.y -1 in Kerala [14]. All these values are higher than the average value of 17±5 µSv.y -1 and 18±5 µSv.y -1 obtained with the present study for Marina and Besant Nagar beach sand samples respectively.…”

The natural radioactivity content of 238U, 232Th and 40K in the intertidal beach sands samples at ten sites each of Marina and Besant Nagar beaches of Chennai city has been analyzed using a 3"x3" NaI(Tl) scintillation detector based gamma ray spectroscopy. The radioactivity content in intertidal sands of Marina were found to be 4±3 Bq.kg -1 , 4±3 Bq.kg -1 and 248±28 Bq.kg -1 respectively; the same were 4±3 Bq.kg -1 , 5±3 Bq.kg -1 and 242±29 Bq.kg -1 respectively in the beach sands of Besant Nagar. These activity levels at both beaches are, in general, much lower than other Indian and World average value. The radiological parameters for both the intertidal sand samples (Marina and Besant Nagar) are far lower than the UNSCEAR 2000 recommended values.

“…Therefore, the radionuclides concentrations and distributions, and its associated dose rates in the beach sands from coastal environments should be monitored. The distribution of primordial radionuclides in coastal sands have been reported by many investigators [3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

“…It is never the less, ICRP has developed a detailed lung model to calculate the effective dose for exposure to air born radionuclides, still a simplification of actual respiratory anatomy and physiological behaviour is needed. More number of researchers has been actively participated in the measurement of ambient gamma radiation level and annual effective dose worldwide [12][13][14][15][16][17][18]. S. Javad Mortazavi M. has been reported that the high background radiation in Ramsar Iran, in this area background radiation is 55-200 times higher than the world average values because this area has dissolved radium in mineral water and deposits having elevated levels of thorium combine with higher concentrations of uranium [19].…”

All individual living beings on the earth are exposed continuously to the radiations coming from terrestrial and extraterrestrial sources and also from their own bodies. The indoor and outdoor ambient gamma radiations are measured in and around Nuggihalli- Holenarasipura schist belts of Hassan district in Karnataka state. The measurements are carried out using the environment radiation dosimeter UR 705 which is a portable detector. Absorbed dose rate and annual effective dose rate are estimated by measuring the exposure rate. The total annual effective dose calculated from both indoor and outdoor varies from 0.68 to1.62 mSv.y-1 with an average value of 1.16 mSv.y-1. The calculated indoor and outdoor annual effective doses are found to be higher than the world average.

“…A. Cardinale et al [1] measured the exposure rate of natural gamma-ray background in representative areas of Italy by a variety of methods, and comprehensively evaluated the impact of gamma-ray radiation on the population of Italy. G. S. Gusain et al [2] used a pocket dosimeter with an NaI detector to measure the land gamma radiation dose rate in the eastern coastal area of the state of Orissa, India, and found high concentrations of monazite and zircon minerals. S.G. Levin et al [3] measured the natural background gamma radiation dose rate in Michigan, Colorado, and Minnesota to determine the relationship between the incidence of congenital disabilities and background radiation.…”

The living environment of human beings is being affected by various types of radiation. Among them, natural radiation has the largest dose. If the dose of natural radiation exceeds a certain threshold level, people will face health risks on multiple fronts. In this work, researchers measured the air-absorbed dose rate at 1 meter above different surface environments on campus and estimated the effective dose equivalent of environmental gamma radiation to the residents. Experiments and analyses show that the radiation level on campus was evaluated based on the measurements. The order of the amount of the radiation dose rate is granite pavement > cement pavement > asphalt ground. According to the experiments, the radiation content of external exposure in the campus is already slightly higher than the limit, i.e. 1mSv/y.
