Use Of Radioactivity In Mining

Apr 10, 2021

Soil radioactivity levels, dose rate and radiological health risk were assessed in metal mining centers of Armenia, at the towns of Kapan and Kajaran. Archive soil samples of the multipurpose soil surveys implemented in Kapan and Kajaran were used for estimation of total alpha and total beta activity levels using gas-less iMatic™ alpha/beta

    Mar 02, 2017 The risks to wildlife and humans from uranium (U) mining in the Grand Canyon watershed are largely unknown. In addition to U, other co-occurring ore constituents contribute to risks to biological receptors depending on their toxicological profiles. This study characterizes the pre-mining concentrations of total arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), mercury (Hg), nickel (Ni)

    Mar 16, 2016 Recently, in the Sudan, traditional gold mining has been growing rapidly and has become a very attractive and popular economic activity. Mining activity is recognized as one of the sources of radioactivity contamination. Hence, the radioactivity concentration and radiological hazard due to exposure of radionuclides 226Ra, 232Th, and 40K were evaluated. The measurements were

    The product of uranium mining is normally uranium oxide concentrate – U 3 O 8 – which is shipped from the mines in 200-litre drums. This is barely radioactive, but has chemical toxicity similar to lead, so occupational precautions are taken similar to those in a lead smelter. Most of the radioactivity from the ore ends up in the tailings

    By the 1950s, Ra-226, the most stable isotope of radium, had been replaced in radiation therapy departments by artificial radioisotopes, such as Cs-137 and Ir-192, and by the 1960s, the commercial use of radium had all but ceased. [3] Today, radium is scarcely used for medical treatments because of its high radioactivity
