Health Effects of Tritium Rosalie Bertell, Ph.D., GNSH
I have directly studied the health effects of ionizing radiation at low dose levels. Therefore I do not rely on extrapolations from high dose and fast dose rate. I disagree with many scientists and nuclear regulators who conduct such unreliable and outdated extrapolations.
Since about 1990 the international radiation research community has fortunately begun to considered low dose health effects in a more direct manner. We no longer guess at a suitable extrapolation from high doses and high dose rates down to the lower doses that are more frequent in radiation protection practice. Many scientists now conducting direct low dose research have been surprised to discover such effects as genomic instability, the bystander effect, an increase in Relative Biological Effect (RBE) at low dose, mini-satellite damage and non-homogeneous distribution of radionuclides, especially for internal exposures, which significantly effect absorbed dose estimates at low levels of exposure.
Tri-Valley CAREs is an anti-nuclear watchdog group focused on the lab since 1983. Using the Freedom Of Information Act, Tri-Valley CAREs found that including two major radiation leaks at the Tritium Facility in the 1960s and 70s, over one million curies of airborne radiation were released by the lab over the last fifty years. Tritium is radioactive hydrogen. Studies show that low-level exposure to tritium is extremely hazardous; there is no safe minimum threshold for radiation exposure to tritium. Over 1,500 claims have been filed by Livermore Lab employees, former employees, or relatives for compensation from on the job exposure to radiation, beryllium and other poisonous substances, resulting in terminal illness or death from working in proximity to these materials.
