1. Radium is tens of times more hazardous than plutonium and thousands of times more hazardous than tritium.
2. Military strategists in the Pentagon, in the British Ministry of Defence and in India independently realise that table-top test-tube fusion should produce not just energy but also neutrons and tritium, crucial ingredients in making atomic and thermonuclear weapons.
3. Dr Simpson found that the spectrum's shape changed at an energy about 17 keV below that of the most energetic electrons emitted by tritium, which led him to suggest that there might be an extra component to beta decay.
4. The nucleus of tritium - the "triton" - has the symbol 3 H or simply t .)
5. If we are ever to achieve a magnetically-confined plasma that is kept hot enough by thermonuclear reactions, then the confinement system must contain the electrically-charged alpha particles that are produced by the fusion of deuterium and tritium.
6. Scientists have known for some time that fusion reactions between nuclei of deuterium and tritium are more likely if the nuclear spins line up in the same direction.
7. While the media perceived test-tube fusion to be a solution to the world's energy problems, it was the possibility of these cells being an intense source of neutrons, and probably of tritium too, that meant that they could have significant military application.
8. Working with a graduate student, Andrew Himes, Dr Simpson decided he had overestimated the number of fat neutrinos, but that he still saw them, both when repeating his work on tritium and when looking at the beta decays of sulphur.
9. (Tritium, however, is radioactive.)
10. However in 1985 John Simpson, of the University of Guelph, in Ontario, Canada, found a kink in his measurements of the beta-decay spectrum of tritium (a radioactive form of hydrogen).
11. The reporters were also told that "evidence that fusion was taking place was the fact that in addition to heat Fleischmann and Pons had detected the production of neutrons, tritium and helium - the expected by-products of fusion reactions".
12. At present no capacity for tritium handling exists in Europe outside the defence community (Britain manufactures tritium for the defence programme at Chapelcross, Dumfries).
13. (There is a third and rarer form of hydrogen, known as tritium, where the proton is joined by two neutrons.
