“…About 20% of the natural radiation dose is due to external radiation from terrestrial radioactivity. [7], [8].When radon gas is inhaled, densely ionizing alpha particles emitted by deposited short-lived decay products of radon 218 Po and 214 Po can interact with biological tissue in the lungs leading to damage and causes lung cancer [9]. Due to the hazardous effect of radon exhalation on human health, it has great significance to conduct measurements of radium content in the soil.…”

Abstract:The natural radioactivity due to uranium, Thorium and potassium in soil contributes to the radiation dose received by human beings significantly. There are quite a few identified monazite sand-bearing placer deposits causing environmental high back ground radiation area along its long coastline of Kerala and Tamil Nadu in India. The extent and effects of the radioactivity in the regions like Chavara and Neendakara in Kollam, Kerala is well known. Other coastal regions are assumed to have normal environmental radiation levels. Following a pilot study along the southern west coast of Kerala state, India we found certain regions with higher levels of natural radioactivity and hence made a detailed investigations of activity concentration of 226 Ra, radon exhalation rates and radon emanating factor of those locations namely Perumathura andVizhinjam. The results indicates that most of the soil sample shows higher specific activity of 226 Ra and there is a linear relation to 222 Rn mass exhalation rate .But radon emanation factor is not so linear to the specific activity of Radium in sample analyzed.

“…Human beings are exposed to natural radioactivity since the inception of the earth which is due to the presence of naturally occurring radionuclides in the surroundings. Exposure to radiation due to natural sources is a continuous and inescapable feature of life on earth [3]. Uranium is one of the radionuclides which is omnipresent and is widely available in the earth's crust.…”

Weathering and erosion of rocks are the main cause for the formation of mineral deposits in beach sand and soil.There are quite a few identified monazite sand-bearing placer deposits causing environmental high radiation area along its long coastline of Kerala and Tamil Nadu in India. The extent and effects of the radioactivity in the regions like Chavara and Neendakara in Kollam, Kerala is well known. Following a pilot study along the southern west coast of Kerala state, India we found certain regions with higher levels of natural radioactivity. Later made a detailed investigation of activity concentration of 226 Ra, radon exhalation rates and radon emanating factor of those locations namely Kovalam and Varkala. The results indicates that most of the soil sample shows higher specific activity of 226 Ra and there is a linear relation to 222 Rn mass exhalation rate. But radon emanation factor is not so linear to the specific activity of Radium in sample analysed.
