Abstract

Successive bombardment of the same target with different ion beams to build up a tailor-made mixture of isotopes. This enables a single multiple tracer experiment to be carried out rather than tediously preparing and purifying many different isotopes and carrying out many different experiments. (refs. 12 and 30). An electrochemical method for the direct nucleophilic reaction of the [ 18 F]fluoride anion with benzene. (ref. 115). The use of super critical carbon dioxide for the extraction of actinide elements (refs. 250 and 251)
