Independent Environmental Monitoring Program: Chalk River Laboratories

Publication date: April 5, 2016

Canadian Nuclear Laboratories Ltd. (CNL) is licensed by the CNSC to operate Chalk River Laboratories (CRL), located in Chalk River, Ontario. CNL operates various nuclear services, including the production of medical isotopes, and conducts a wide variety of research programs at the facility. CNL runs a comprehensive environmental protection program to monitor and control nuclear and hazardous substances released from the CRL facilities, determine concentrations of contaminants in the environment, and assess exposure to the public.

The Independent Environmental Monitoring Program (IEMP) results for 2015, 2013 and 2012 confirm that the public and the environment around the CRL facilities are safe and that there are no health impacts.

1The < symbol indicates that a result is below the provided laboratory analytical detection limit.

2For water samples, the results for non-radiological parameters are compared to CCME Guidelines for the Protection of Aquatic Life; where no CCME guidelines exist, the Health Canada Drinking Water Quality Guidelines are used.

3For radiological parameters where no guidelines exist, CNSC reference levels were established based on conservative assumptions using CSA Standard N288.1-14. The reference level for a particular radionuclide in a particular medium (e.g., water, air, food) represents the activity concentration that would result in a dose of 0.1 mSv/a, a dose at which no health impacts are expected.

4Tritiated water (HTO) concentrations in soil are presented on a fresh weight basis. This indicates the concentration in bulk soil, for which HTO is contained in the soil pore water.

Background

Under the Nuclear Safety and Control Act (NSCA), licensees of nuclear facilities are required to implement an environmental monitoring program to demonstrate that the public and the environment are protected from emissions related to the facility’s nuclear activities. The results of these monitoring programs are submitted to the Canadian Nuclear Safety Commission (CNSC) to ensure compliance with applicable guidelines and limits, as set out in regulations that oversee Canada’s nuclear industry.

The CNSC has implemented its IEMP to verify that the public and the environment around licensed nuclear facilities are safe. It is separate from, but complementary to, the CNSC’s ongoing compliance verification program. The IEMP involves taking samples from public areas around the facilities, and measuring and analyzing the amount of radiological (nuclear)and hazardous substances in those samples. CNSC staff collect the samples and send them to the CNSC’s state-of-the-art laboratory for testing and analysis.

2015 results

The 2015 IEMP sampling plan for the CRL site focused on both nuclear and hazardous contaminants. A site-specific sampling plan was developed based on CNL’s approved environmental monitoring program, CSA Group standards and the CNSC’s regulatory experience with the site. In 2015, samples were collected in publically accessible areas outside the CRL site perimeter and included river and lake water, soil and river sediment, and food such as milk, meat, and produce from local farms outside of the CRL perimeter fence. The site specific sample plans are reviewed by CNSC staff on an annual basis to continuously improve and refine the plans to meet the objectives of the program. View detailed sampling data.

The radioactivity measured in water, sediment, soil and vegetation samples, as well as samples of milk and meat, were below CNSC reference levels and are within natural background levels. CNSC reference levels are based on conservative assumptions about the exposure that would result in a dose of 0.1 mSv/year. No health impacts are expected at this dose level.

With respect to the non-radiological analysis, the concentrations of analyzed substances in water and soil samples were, in general, below or close to the Canadian Council of Ministers of the Environment’s guidelines and the natural background levels. No health or environmental impacts are expected at these levels.

 

2013 results

The 2013 IEMP sampling plan for the CRL site focused on both nuclear and hazardous contaminants. A site-specific sampling plan was developed based on CNL’s approved environmental monitoring program, CSA Group standards and the CNSC’s regulatory experience with the site. In 2013, samples were collected in publically accessible areas outside the CRL site perimeter and included river and lake water, soil and river sediment, and food such as milk, meat, and produce from local farms outside of the CRL perimeter fence. The site specific sample plans are reviewed by CNSC staff on an annual basis to continuously improve and refine the plans to meet the objectives of the program. View detailed sampling data.

2012 Results

The 2012 IEMP sampling plan for the CRL site focused on both radiological (nuclear) and non-radiological (hazardous) contaminants. A site-specific sampling plan was developed based on CNL’s approved environmental monitoring program, Canadian Standards Association (CSA) standards and the CNSC’s regulatory experience with the site. In 2012, samples were collected in publicly accessible areas outside the CRL site perimeter and included river and lake water, soil and river sediment, and food such as milk, meat and produce from local farms outside of the CRL perimeter fence. View detailed sampling data.

The radioactivity measured in water, sediment, soil and vegetation samples, as well as samples of milk and meat, were below CNSC reference levels and are within natural background levels. CNSC reference levels are based on conservative assumptions about the exposure that would result in a dose of 0.1 mSv/year. No health impacts are expected at this dose level.

With respect to the non-radiological analysis, the concentrations of analyzed substances in water and soil samples were, in general, below or close to the Canadian Council of Ministers of the Environment’s guidelines and the natural background levels. No health or environmental impacts are expected at these levels.

Conclusions

The IEMP results confirm that the public and the environment around the CRL site are safe and that there are no expected health impacts. These results are consistent with the results submitted by CNL, confirming that the licensee’s environmental protection program protects the health and safety of people and the environment.
