Natural radionuclides of U and Th series are present in many natural sources. High concentrations of these elements are found in geologic materials, rocks and minerals. Human activities may cause a significant increase in concentration of these elements, defined as TENORM, and a potential increase of exposure to natural radiation in products, by-products and waste. Important examples of t…

The natural radiation is responsible for most of the radiation exposure to the population in general is subject. It is estimated that the annual average dose resulting from natural sources is approximately 2.4 mSv, and 1.3 mSv arising only from radon decay product of 238U. It is known that the ventilation rate is one of the factors that contribute strongly to the concentration of 222Rn in…
The phosphogypsum is a byproduct of the phosphate fertilizers industry, and it is generated on a large scale in Brazil. It is estimated the amount stockpiled is approximately 69 million tonnes. Although the composition of phosphogypsum is basically calcium sulfate dihydrate, the material may contain high levels of impurities that come from phosphate rock used as raw material. Among these …
The use natural radioactivity in environmental studies is a very important tool to determine the dynamics of both natural and antrophogenic processes in environment. The sediments of lacustrines environments contain a repository of valuable historical information on the temporal changes of industrial pollution. The knowledge of the rate at which sediments have been accumulating is of fund…
