FYI, Tritium is a relatively weak source of radiation. It emits beta particles at such a low level they are unable to penetrate human skin. Tritium can be hazardous, but only if it’s ingested in large quantities. If you drank water contaminated with tritium at the EPA limit, over a year you'd be exposed to about 4 millirems of radiation. In comparison, a cross-country airplane flight results in an exposure of about 3 millirems, and an X-ray can be 10 to 25 millirems or higher.
