Electret ionization chambers are widely used for measuring radon and radiation. The radiation measured includes alpha, beta, and gamma radiation. These detectors do not have any electronics and as such can be introduced into magnetic field regions. I

The production of phosphoric acid by acidulation of rock phosphate with sulfuric acid produces phosphogypsum (PG) as a byproduct. Phosphogypsum is primarily CaSO 4 .2H 2 O and is a potential source of S and Ca for crops. Because of the presence of sm

This theoretical study of the alpha star populations in loaded emulsions was undertaken in an effort to find a quantitative method for the analysis of less than microgram amounts of thorium in the presence of larger amounts of uranium. Analytical exp

Uranium-bearing minerals that give lead-uranium and lead—lead ages that are essentially in agreement, i.e. concordant, generally are considered to have had a relatively simple geologic history and to have been unaltered since their deposition. The

The Po-210 data, disequilibrium measurements, and nuclear-emulsion observations combine to provide an internally consistent picture in which Ra-226 is relatively free to move and is now doing so. Rn-222 is also free to move, but the distance this iso

Abundant evidence for the recent separation, transport and redeposition of Ra-226 has been obtained. On the basis of both alpha star populations and possibly the presence of numerous barite grains containing Ra-226, unsupported Ra-226b appears to be
