“…Radionuclide of uranium and thorium series has been reported in FA (Eisenbud and Petrow 1964;Tadmore 1986;Papastefanou 2008). According to Zielinski and Finkelman (1997) majority of FA are insignificantly enriched in radioactive elements or in associated radioactivity compared to common soils or rocks, but this problem is quiet concern.…”

Over the past few decades there has been avid interest in developing the strategies for the utilization of Fly ash (FA). Major foci have been on its agricultural application. It is often economical to use FA as a soil amendment. The potential of FA as a resource material in agriculture is due to its specific physical properties like's texture, water holding capacity, bulk density, pH etc., and contains almost all the essential plant nutrients. It can be used as in soil that cannot substitute the chemical fertilizers or organic manure it can be used in combination with these to get additional benefits in terms of improvement in soil physical characteristics, increased yields etc. The amount and method of FA application in soil would vary with the type of soil, the crop, grown, the prevailing agro climatic condition and also with the FA characteristics. Although, as an input material FA has many benefits for agriculture applications like, improvement of nutrient deficiency, effectively control various pests infesting etc., in contrast FA also contains number of toxic heavy metals and also have natural radioactivity materials in it. Therefore, proper attention should be given on some important areas related to FA utilization such as long term studies of impact of FA on soil health, heavy metal uptake, plant physiology and growth, crop quality, and continuous monitoring on the soil characteristics. While using FA in agriculture problem of heavy metal toxicity and leaching due to excess dose should also be kept in mind.

“…At the beginning of the "nuclear era", some efforts were made to use U-bearing coals as a source of the U. However, with the discovery of higher-quality raw sources, the interest in U-bearing coals diminished and now they are considered to be potentially dangerous source of radioactive contamination of the environment (Bauman and Horvat, 1981;Bride and Moore, 1978;Eisenbud and Petrow, 1964;Mazuricheva and Kiselev, 2004). The world coal industry focuses on coals with low concentrations of radioactive elements.…”

“…Thus, coal combustion is considered as one source of radioactive material in the environment [2][3][4][5]. Though it is controversial, the radiation doses from atmospheric emission of a coal-fired power plant were considered to be greater than those from a nuclear plant of comparable size [6,7]. In 1978, it was reported that as high as 2,975 kg uranium were emitted into the atmosphere from one Chinese coal-fired power plant [8].…”

Due to its environmental and resource impacts, the geochemistry of uranium in coal is of both academic and practical significance. In order to give a comprehensive summary about the geochemistry of uranium in coals, the abundance, distribution, and modes of occurrence of uranium in Chinese coals were reviewed in this paper. Although some coals from southwestern and northwestern China are significantly enriched in uranium, the common Chinese coals are of a comparable uranium concentration to the world coals. The roof and floor rocks, and parting of coalbeds, or coal benches that are close to the surrounding rock are favorable hosts for uranium in one coalbed. The uranium concentrations in coals of different ages decrease in this order, e.g., Paleogene and Neogene > Late Permian > Late Triassic > Late Carboniferous and Early Permian > Late Jurassic and Early Cretaceous > Early and Middle Jurassic. Uranium in Chinese coals is mainly associated with organic matter, and is correspondingly enriched in subbituminous coal and lignite.
