Abstract : Carrier-free radioactive phosphorus can be prepared in the pile by (n,p) process on sulfur(32). There are no by-products in this material except those formed from nuclear reactions of the chemical contaminants. About 2 kg of specially purified sulfur is irradiated in a large aluminum can in the pile for a period of at least six weeks. The contents of the can are melted out, and the active phosphorus is extracted with weak nitric acid under pressure at a temperature greater than 120 deg C employing mechanical agitation. The waste molten sulfur and the active phosphorus extract are separated, and the latter is processed in order to remove chemical contaminants. Thus carrier-free active phosphorus produced in the Clinton pile is chemically separated from sulfur in multi-millicurie quantities.
