By means of radiation "defectoscopes," which are described above, we can carry out industrial control. The speed of this operation is higher if we use low-inertia recording devices, such as oscillographs. Institute of Mining of the Get Price

Solar Radiation Estimation Using Data Mining Techniques

High quality of solar radiation data is essential for solar resource assessment. For remote areas this is a challenge, as often only satellite data with low spatial resolution are available. This paper presents an interpolation method based on topographic data in digital elevation model format to improve the resolution of solar radiation maps. The refinement is performed with a data mining Get Price

Book Review: Occupational Radiation Protection in the

2020/08/21Underground and surface mining of uranium ores is generally like the mining of other types of ore. However, in situ leaching is specific to uranium and comprises more than 50% of uranium production. It involves the circulation of groundwater fortified with oxygen and a chemical additive that may be either slightly acidic or slightly alkaline. Get Price

Determination of natural radioactivity and hazard in soil

2014/07/01Radiation exposures arising in the mining and mineral processing industries are in three ways. These are external gamma radiation from ores, inhalation of dusts containing long-lived alpha-emitting radionuclides and inhalation of the short-lived decay products of radon ( UNSCEAR, 2000 ).
