Health Canada’s Canadian Radiological Monitoring Network (CRMN) is a national network that routinely collects environmental samples for radioactivity analysis. More information about the CRMN network can be found here: https://www.canada.ca/en/health-canada/services/environmental-workplace-health/environmental-contaminants/environmental-radiation/canadian-radiological-monitoring-network.html
This dataset provides radionuclide activities in precipitation. The radioactivity results come from the analysis of precipitation collected monthly from a rain sampler in the field from each of our network stations. The CRMN analyses precipitation samples on an as-needed basis.

Health Canada routinely collects environmental samples for radioactivity analysis. The backbone of its monitoring comes from three separate networks: The Canadian Radiological Monitoring Network (CRMN), the Fixed Point Surveillance Network (FPS), and a Canadian contribution to the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTo). This dataset provides the approximate sampling location of the monitoring stations for each network. CRMN is a national network that routinely collects air particulate, precipitation, external gamma dose, drinking water, atmospheric water vapour, and milk samples for radioactivity analysis.

This dataset provides the background radiation dose results from Health Canada’s Canadian Radiological Monitoring Network (CRMN) monitoring sites. More information about the CRMN network can be found on the Health Canada website (see link below). This background radiation data contains both “monitoring” and “transit” dosimeters starting in 2016. The historical background radiation dose data can be found on the Open Data portal.

This dataset provides results obtained by Health Canada’s Canadian Radiological Monitoring Network (CRMN) for 90Sr activity in milk samples originating from various locations across Canada. More information about the CRMN network can be found on the Health Canada website (see link below). From 1984 to 1993, data was collected from 20 locations. After 1993, routine milk analysis for radio-strontium activity was discontinued for all monitoring stations, except the Ottawa location.

This dataset provides the results obtained by Health Canada’s Radiological Monitoring Network (CRMN) for the tritium activity concentration in drinking water originating from the water treatment plants in Ottawa, ON. More information about the CRMN network can be found on the Health Canada website (see link below). The results provided are the tritium activity concentration in units of becquerels per litre (Bq/L). Although ensuring water quality is a matter of provincial jurisdiction, the CRMN, in collaboration with the city of Ottawa, has been conducting a targeted program to monitor the radiological content of drinking water from two water treatment plants in Ottawa, ON.

This dataset provides the results obtained by Health Canada’s Radiological Monitoring Network (CRMN) for tritium content in atmospheric water vapor sampled from monitoring stations in Ontario, Quebec and New Brunswick. More information about the CRMN network can be found on the Health Canada website (see link below). The results provided are for tritium activity concentration, expressed in units of becquerels per cubic meter (Bq/m3). Atmospheric water is sampled monthly for determination of tritium content.

This dataset contains the historical (prior to 2015) environmental dosimetry results. The current data can be found here: http://open.canada.ca/data/en/dataset/67bedee8-beb0-4b3a-a1c6-24a4cda08afe. The data after 2015 is provided in SI units of millisieverts (mSv) to be more in-line with current best practices. This dataset provides the thermoluminescent dosimetry (TLD) data from monitoring stations across Canada, obtained by Health Canada’s Canadian Radiological Monitoring Network (CRMN).

This dataset provides the results obtained by Health Canada’s Canadian Radiological Monitoring Network (CRMN) for the gross alpha and beta activity concentrations in drinking water, given in units of becquerels per liter (Bq/L). More information about the CRMN network can be found on the Health Canada website (see link below). Although water quality is a matter of provincial jurisdiction, the CRMN, in collaboration with the city of Ottawa, has been conducting a targeted program to monitor the radiological content of drinking water from two water treatment plants in Ottawa, ON. The Guidelines for Canadian Drinking Water Quality recommend screening levels of 0.5 Bq/L and 1.0 Bq/L for gross alpha and gross beta activity, respectively.

"This dataset provides the results obtained by two radiation monitoring networks operated by Health Canada: the Canadian monitoring sites of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) and the Canadian Radiological Monitoring Network (CRMN). More information about the CTBT and its monitoring network is available here: http://www.hc-sc.gc.ca/ewh-semt/contaminants/radiation/nuclea/index-eng.php and http://www.ctbto.org/. Further information on the CRMN network is available at: http://www.hc-sc.gc.ca/ewh-semt/contaminants/radiation/crmn-rcsr/index-eng.php. The results provided are activity concentration and uncertainty for various nuclides in the months following the Fukushima Daiichi nuclear accident.

The Airborne Radionuclide Concentrations (ARC) Dataset is a general dataset of airborne radionuclide concentrations analyzed at the Radiation Protection Bureau (RPB). The RPB is responsible for delivering Health Canada’s program in the area of ionizing radiation protection. This dataset includes radionuclide concentrations at locations in RPB’s Canadian air monitoring networks including its Comprehensive Nuclear Test-Ban Treaty (CTBT) stations and the Canadian Radiological Monitoring Network (CRMN). The dataset may also include additional airborne radionuclide concentration data from other networks, fieldwork and any additional data collected during emergencies.
