Electrostatic charge on uranium ore dust

Miscellaneous:

Abstract

A system of four elutriators was constructed in order to estimate the median charge on airborne uranium ore dust particles generated during the drilling in the open pit of the Ranger Uranium Mines in the Northern Territory of Australia. The surface alpha activity of the electrodes was measured as a function of distance from the elutriator`s inlet. By analysing this data along with the measured activity mean aerodynamic diameter of airborne uranium ore dust, a median electrostatic charge of about 33 electrons was calculated for a {mu}m particle. The above charge has a negligible effect on the lung deposition of U-ore dust generated by drilling of the U-ore body. 7 refs., 2 tabs., 3 figs.
