Abstract:
Tritium intake may occur in certain workplaces by design or by accident. If the health physics staff has developed a formal bioassay program, then it is likely that dose estimates from tritium intake are readily determinable. However, in the case of tritium intake at a facility where no formal program exists, it may be necessary to make simple confirmatory estimates of dose due to tritium exposure. Lifetime dose estimates may be calculated by using data from urine samples taken over a period of time. If urine data are unavailable, estimates of committed dose equivalent may be made with air sample data and knowledge of workplace activities.
