Half of the HTO is eliminated from
the body in about 10 days. Through
normal biological processes, it would
take 70 days or more to eliminate
99% of the assimilated tritiated water.
Stable tritium particulate aerosols and
insoluble organically bound tritium
behave in the body in a similar
manner as the particulate to which
the tritium is bound and would have a
longer half life.

The biological half-life can be shortened by increasing
the water elimination in the body. Therefore,
individuals who have uptakes of tritium are
encouraged to drink water. Drinking copious amounts
of water should not be done without a physician's
guidance. Certain medical conditions may be affected
by liquid intake.

RADIOLOGICAL CONTROLS FOR TRITIUM - How can I
protect myself from exposures to tritium?
Tritium can be present in a variety of chemical forms. Ongoing
research indicates that the form of tritium which gives the
highest dose (per unit intake) is tritium particulate aerosols.
However, these compounds are not found in the quantities and
various locations as tritiated water. If we can rule out special
tritium compounds as being of concern, we assume it may be

The preferred hierarchy of control is as follows:
