Ontario Power Generation sells waste tritium from CANDU reactors to two Ontario companies that manufacture tritium lights, SRB Technologies in Pembroke and Shield Source in Peterborough. These companies use the tritium to make self-luminous exit signs. TAP believes that the marketing of radioactive waste in these products should be prohibited. Safer, more effective and more energy efficient alternatives are available.
Besides being hazardous during manufacture and disposal, tritium lights and products containing them are hazardous during use. The tritium contained in a single exit sign, if fully oxidized and inhaled would constitute a lethal dose of radiation. Incidents have occurred in the United States where lights have been accidentally or intentionally broken, thus requiring expensive emergency measures including evacuations and decontamination operations.
This and other problems are described in the TAP fact sheet “Problems with tritium exit signs” available in PDF format for download in the documents section of this website.
We have just posted several archival news stories here on the TAP website, dealing with tritium pollution from SRB Technologies Inc. in Pembroke, Ontario. This story is incredible but true.
SRB was licensed by the Atomic Energy Control Board (now the Canadian Nuclear Safety Commission) in 1990 to market a radioactive waste byproduct of CANDU reactors called tritium — a radioactive form of hydrogen. SRB makes self-illuminating signs — they glow in the dark because they are filled with large quantities of radioactive tritium gas.
Over the years. SRB has contaminated the environment in Pembroke with high levels of tritium. In some years, more tritium was given off into the environment by the SRB plant than by all of Canada’s nuclear power reactors combined. Meanwhile, SRB is exporting tritium contamination problems around the world because there is no effective control over the ultimate disposal of these radioactive signs.
This story is replete with patent examples of regulatory incompetence, murky questions about nuclear weapons and international security risks (because tritium is also used as a nuclear explosive material) and salt-of-the-earth folks being treated with disregard and exposed to high levels of radioactive tritium for almost 20 years with no end in sight. Please see also the “personal stories” category for more about this.
TAP feels that the marketing of radioactive wastes like tritium should be banned in Canada, and the SRB plant should be permanently shut down.
