The thermonuclear bomb-pulse is clearly preserved in the tritium profile. The goal of the research is to expand the body of knowledge on tritium and to further enhance regulatory oversight of tritium-related activities in Canada. However, the Commission does not view that this situation is an indication that SRBT is not qualified to carry on activities related to processing and using tritium. No association was detected for external whole body dose, tritium dose, or radon exposures, or for any of the preconception or prediagnosis periods of exposure. Show More Sentences Several initiatives have been undertaken to reduce doses from tritium, including more frequent replacement of desiccant in dryer units and improvement of the material condition of dryer systems. In all cases, tritium releases are strictly controlled and represent a small fraction of regulatory limits and, therefore, do not represent a risk to people's health or the environment. The argon gas in the glove box is continuously recycled through a titanium getter bed, which removes oxygen, nitrogen, water vapour, hydrogen and tritium. The staff at the Tritium Laboratory at Chalk River believes that the diffusion of tritium from the getter bed contributes a significant amount to the tritium concentration in the secondary containment glove box.

The big thing with fusion is that the deuterium and lithium, which is used to make tritium, used in the fusion process are available in vast amounts-they are abundant in the earth and in the sea. The fusion of deuterium and tritium into helium in this way releases energy enough of it, in theory, both to power the reactor and to yield a surplus that can be converted into electricity. In principle, nuclear energy may be generated both by the fission of very heavy atomic nuclei such as uranium or plutonium and by the fusion of very light atomic nuclei such as deuterium or tritium. At ITER, fusion will be the combination of two of these light atoms, deuterium and tritium, to form a more stable heavy atom, helium, and a neutron, both of which carry kinetic energy. In a typical two-stage weapon, the fissile materials detonate first to compress and heat the fusion fuels, such as hydrogen isotopes tritium and deuterium, to tens of millions of degrees. The intervenor further noted that tritium behaviour in the atmosphere is not easily predicted and thus SRBT should not be allowed to operate outside of a closed system, within close proximity of a residential area.
