A preferential dissolution by a factor of 1.1 to about 10 of the radiogenic nuclides /sup 234/U, /sup 230/Th, and /sup 228/Th relative to their corresponding structurally incorporated isotopes /sup 238/U and /sup 232/Th has been observed upon leaching of natural monazite samples in a bicarbonate-carbonate solution. This isotopic fractionation may be attributed to radiation damage caused by alpha recoil atoms. The observations have implications for the storage of crystalline nuclear waste forms… CONTINUE READING
