Today, sources of tritium include commercial nuclear reactors and research reactors, and government weapons production plants. Tritium may be released as steam from these facilities or may leak into the underlying soil and ground water.
Tritium can also enter the environment from improper handling, or illegal disposal of exit signs in municipal landfills. As water seeps through landfills, it can spread the tritium from the broken signs. Regulations require that tritium exit signs be returned to a licensed facility for disposal.
Tritium emits a very weak beta particle. People are exposed to small amounts of tritium every day, since it is widely dispersed in the environment and in the food chain. Tritium primarily enters the body when people swallow tritiated water, inhale tritium as a gas in the air, or absorb it through their skin.
Once tritium enters the body, it disperses quickly and is uniformly distributed throughout the body. Since tritium is almost always found as water, it goes directly into soft tissues and organs. Tritium is excreted through the urine within a month or so after ingestion.
