“…Under differing circumstances and conditions, both Radon gas as well as its short lived daughter products (Po 218 ,Pb 214 , Bi 214 , Po 214 ) can be important concerns in occupational health physics programs. A great deal of information exists in the literature confirming that the daughters of Radon are considerably more important than the Radon parent in contributing to respiratory track dose (Coleman et al, 1956;Holaday et al, 1957;Jacobi, 1964;Altshuler et al, 1964;Schiager and Dahl, 1968). Extensive Radon and Radon daughter monitoring at these ISL facilities indicated that severe disequilibrium can be encountered between Radon and its daughters at both ends of the continuum.…”

In the last few years, there has been a significant increase in the demand for Uranium as historical inventories have been consumed and new reactor orders are being placed. Numerous mineralized properties around the world are being evaluated for Uranium recovery and new mining / milling projects are being evaluated and developed. Ore bodies which are considered uneconomical to mine by conventional methods such as tunneling or open pits, can be candidates for non-conventional recovery techniques, involving considerably less capital expenditure. Technologies such as Uranium In Situ Leaching / In Situ Recovery (ISL / ISRalso refered to as "solution mining"), have enabled commercial scale mining and milling of relatively small ore pockets of lower grade, and are expected to make a significant contribution to overall world wide uranium supplies over the next ten years. Commercial size solution mining production facilities have operated in the US since the mid 1970's.
