Tritium-laced plants found near town’s glow-in-the-dark sign factory

Radioactive rhubarb has been found growing in Pembroke, Ont., near a factory that makes glow-in-the-dark signs from nuclear waste.
The rhubarb, apparently thriving downwind of the sign factory owned by SRB Technologies (Canada) Inc., contained about 1,000 times the radioactive tritium found either in rain water in Ottawa or in a rhubarb sample taken from a garden about 45 kilometres away.
“It was unusually large rhubarb, but I don’t think it was mutant or anything like that,” said Ole Hendrickson, a resident of the Ottawa Valley community who helped collect the samples. Read more…

Radioactive matter shows up in rink ice, cucumbers, and woman’s urine
High levels of radioactive tritium are being found throughout Pembroke, the site of a plant that recycles the waste material to make glow-in-the-dark signs. Tritium has been discovered in the ice of a local hockey rink, in cucumbers and in the urine of one of the residents of the Ottawa River Valley city.
Although the tritium levels that were found were up to 1,500 times higher than the concentrations in rainwater, the Atomic Energy Control Board says they pose negligible risk of causing cancer. Read more…
After discovering groundwater contaminated with radioactive tritium, regulatory agency recommends shutting company

Alarmed about radioactivity levels around Pembroke, Ont., that are hundreds of times above normal, staff at Canada’s nuclear regulatory agency have taken the unprecedented step of recommending the closing of a manufacturer of glow-in-the-dark signs.
Staff at the Canadian Nuclear Safety Commission have found that emissions from the company, SRB Technologies (Canada) Inc., have created a trail of groundwater contaminated with radioactive tritium more than a kilometre long under the Ottawa River Valley community of 15,000. The most contaminated water had tritium levels 743 times normal. Read more…

The federal government is licensing companies to handle dangerous nuclear materials that have both peaceful and military uses without knowing who ultimately owns the businesses.
Nuclear critics say the fact that the Canadian Nuclear Safety Commission, the federal watchdog agency, does not know the identity of owners of the companies it oversees is a major blunder, given the high-security risks presented by nuclear materials and the potential costs of any accident involving radioactive releases.

The Canadian Nuclear Safety Commission approved a shipment to Iran last year by a Canadian company of about 70,000 glow-in-the-dark lights containing tritium, a radioactive gas that can also be used as a component in hydrogen bombs.
The amount of tritium approved by the nuclear regulator for shipment to the volatile Middle Eastern country was about 10 per cent of the quantity considered necessary for making one nuclear weapon, although the company selling the lights, SRB Technologies (Canada) Inc., said it sent less than it was allowed.

Nuclear watchdog may ask atomic agency to monitor Ontario company’s tritium use
The International Atomic Energy Agency, the body that tries to stop the proliferation of nuclear weapons, should inspect SRB Technologies (Canada) Inc., a Canadian company that uses radioactive tritium, according to an internal report by the Canadian Nuclear Safety Commission.
The recommendation will be reviewed by the commission, Canada’s nuclear watchdog, at a licence hearing for SRB next week. If approved, it would place the Pembroke, Ont., company in the same league in terms of inspections as facilities that have stockpiles of fissile material that could be converted into atomic weapons.

A company in Eastern Ontario is hoping to find that the solution to pollution is dilution.
The company, SRB Technologies Canada Inc. of Pembroke, Ont., has contaminated the groundwater around its factory with radioactive tritium, raising the ire of nuclear regulators. So it is proposing to clean up the problem by dumping some of the pollutant into the city’s sewers.
From there, the radioactivity would be mixed with sewage flushed by the city’s 13,000 residents and ultimately poured into the nearby Ottawa River. Read more…

Pembroke facility shuts down operations temporarily amid
radioactivity concerns
By MARTIN MITTELSTAEDT
Thursday, December 1, 2005
A company that contaminated groundwater around its plant in Pembroke, Ont., with radioactive tritium says it has halted operations and will not resume manufacturing until it puts in place better pollution controls.
SRB Technologies (Canada) Inc. announced its temporary shutdown in an e-mail sent late Tuesday night to the Canadian Nuclear Safety Commission, the country’s nuclear watchdog agency. The letter was sent just before the company was scheduled to appear at a CNSC hearing yesterday into the future of the plant. Read more…

The Ministry of Environment has found elevated levels of radioactive tritium in ground water at the municipal dump serving Pembroke, Ont., and several other nearby Ottawa River valley communities.
The dump, the Alice and Fraser Township Landfill, is not licensed to receive radioactive waste, and it is not known exactly how tritium, used to make glow-in-the-dark lights, among other products, and nuclear weapons, got into the dump. Read more…
Our TAP press conference on Parliament Hill Wednesday has raised concern about Ottawa’s drinking water among some members of the media and general public. People are surprised to learn that drinking water in Ottawa is radioactive. Perhaps this is because previous media reports included assurances from authorities like this one:
“Radioactive water never reached river: Feds” (Ottawa Sun, January 30, 2009_
Peter Zimonjic The federal government says no radioactive material from a recent leak at
the Chalk River nuclear research facility made its way into the Ottawa River…
No wonder people are upset to learn that in fact millions of bequerels of radioactive tritium entered the Ottawa River in December and subsequent spills in January and February.
Data released yesterday by the City of Ottawa show that the Ottawa River is chronically contaminated with tritium at the level of 6 bq / litre. This level is more than three times the background level. In essence this means that in every litre of tap water in Ottawa, there are six radioactive decay events going off every second, second after second. This is equal to more than or 20,000 every hour, and more than half a million per day in this one litre of tap water.
When you drink water with tritium in it, much of the tritium passes through the body. However, small quantities get absorbed into organic molecules in the body including DNA. Inside organic molecules and especially in DNA, tritium can do significant damage. TAP’s position is that it’s good to keep tritium out of drinking water for this reason.
