Sorption and migration of transplutonium elements in natural systems

This paper examines several aspects of the possible behavior of long-lived transuranium and transplutonium elements when they enter the rock stucture of the earth's crust. The long-lived isotopes Np 238, Am 241, 243, Cm 244, 245, 246, and Pu 239, 240, 242, 244 present the greatest danger. Experimental data indicate that in most aluminosilicate rocks, the most significant variables for sorption processes are the forms in which the isotope exists in the natural water system and the ransformations that they can undergo.
