Nuclear parts made of uranium or plutonium, as well as radioactive tritium gas, are shipped to other Energy Department centers, often transported by highways in innocuous-looking trucks.

A small quantity of tritium gas was released, but the teen-ager was not harmed, officials said.

Varying primary yield by boosting with fusion, using small amounts of deuterium / tritium gas inside the primary fission bomb to increase its yield.

The inside of the tubes is coated with a fluorescent powder, which glows as a result of the ionizing radiation of the tritium gas.

This effect came from a small glass tube of tritium gas, which gave off beta radiation and made the dial fluoresce.

The other four probably will not unless we complete the replacement of the tritium gas triggers and certain other components.

Tritium lighting is made using glass tubes with a phosphor layer in them and tritium gas inside the tube.

A small quantity of tritium gas was also provided in order to test the plant's ability to purify tritium.

The department said it would also continue to test and develop a linear accelerator to produce the tritium gas, which enhances the explosive power of nuclear warheads.

But as he cut into one using a power saw, an alarm sounded, and he realised there'd been a leak of radioactive tritium gas.
