Measurement of Natural Radioactivity in Coal, Soil and ...
2013-3-4 The activity concentrations of naturally occurring radionuclides Ra-226, Th-232 and K-40, were measured by using a gamma ray spectrometry for coal, soil and water samples collected from the Barapukuria coal mine in Dinajpur district of Bangladesh. The average activity concentrations of Ra-226, Th-232 and K-40 in coal samples were found to be 6.21±3.68, 10.69±7.5 and 185.76±138.86

Measurement of natural radioactivity in several sandy ...
2020-3-1 The presence of mineral matter in coal may result in a number of environmental and human health problems related to its mining. During coal mining activities, large quantities of coal dust, ashes, and heavy metals are released into the environment, forming a complex mixture (Mejía et al., 2016). Briefly, air pollution occurs due to blasting ...
