D-3He Fusion

We had previously noted that d-t fusion involves radioactive tritium as a fuel and high energy neutrons as reaction products; the former poses problems of radiological safety because tritium diffuses readily, while the latter leads to difficulties of first-wall endurance, shielding and induced radioactivity. Similarly d-d fusion produces both tritons and neutrons, e. g. Table 7.1.
