In case you haven't seen this yet: http://www.nirs.org/factsheets/tritiumbasicinfo.pdf Excerpt: Most studies indicate that tritium in living creatures can produce typical radiogenic effects including cancer, genetic effects, developmental abnormalities and reproductive effects. (Straume) Tritium can cause mutations, tumors and cell death. (Rytomaa) Tritiated water is associated with significantly decreased weight of brain and genital tract organs in mice (Torok) and can cause irreversible loss of female germ cells in both mice and monkeys even at low concentrations. (Dobson, 1979) Studies indicate that lower doses of tritium can cause more cell death (Dobson, 1976), mutations (Ito) and chromosome damage (Hori) per dose than higher tritium doses. Tritium can impart damage which is two or more times greater per dose than either x-rays or gamma rays. (Straume) (Dobson, 1976) There is no evidence of a threshold for damage from 3H exposure; even the smallest amount of tritium can have negative health impacts. (Dobson, 1974) Organically bound tritium (tritium bound in animal or plant tissue) can stay in the body for 10 years or more. While tritiated water may be cleared from the human body in about 10 days (Garland), if a person lives in an area where tritium contamination continues, he or she can experience chronic exposure to tritium. (Laskey) Tritium from tritiated water can become incorporated into DNA, the molecular basis of heredity for living organisms. DNA is especially sensitive to radiation. (Hori) A cell’s exposure to tritium bound in DNA can be even more toxic than its exposure to tritium in water. (Straume)(Carr) Cindy Folkers, NIRS, April 2006
