Studies on the multielemental uptake by thiosemicarbazide incorporated Amberlite IRC-50 using tracer packet technique

Abstract

1152-1155Irradiation of a thick cobalt target with 16O, 7Li and 12C beams consecutively produces carrier-free radiotracers of 6ICU, 62,63Zn, 66,67Ga, 71,72 As and 73Se, which are of nutritional importance and are closely related in the periodic table. A gold target irradiated with medium energy 7Li and 12C produces 197Hg, 198,199,200,201Tl, 199,200,201 Pb, 204 Bi and 204,205po, which are heavy as well as toxic in the environment. A new term, 'Tracer Packet' has been coined for such systems. The uptake of these elements has been studied using a chelating resin, thiosemicarbazide incorporated amberlite IRC-50
