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. The majority of such monitoring activity occurs in close proximity to nuclear power plants. Until 1996, Health Canada monitored the areas near Darlington, Bruce and Pickering in Ontario, Gentilly in Quebec, and Point Lepreau in New Brunswick. In 1996, Health Canada’s monitoring of the Ontario stations was terminated to avoid redundancy, since a similar initiative was underway through the Ontario Ministry of Labour. Currently, the CRMN monitors six sites in the vicinity of Point Lepreau, four sites in the vicinity of Gentilly, and a single site in the Greater Toronto Area. The average tritium concentration for the CRMN stations is 0.22 Bq/m3 for the time period from 2004 to 2013. This is consistent with results reported for other monitoring stations in close proximity to Canadian nuclear power stations, and the levels are considered to be safe from a health perspective. Note that the tritium values are measured using liquid scintillator measurements. This requires removing the background contribution from the measurement. The uncertainty associated with each measurement, can lead to reported values of less than zero. The map shows the approximate sampling location for each monitoring station. Stations are found within the associated location range.

This dataset provides the results obtained by Health Canada’s Radiological Monitoring Network (CRMN) for airborne radioactivity content at monitoring stations across Canada. More information about the CRMN network can be found on the Health Canada website (see link below). The results provided are activity concentration, uncertainty and the minimum detectable concentration for the naturally occurring radionuclides, beryllium-7 (7Be) and lead-210 (210Pb), and the anthropogenic (originating from human activity) radionuclides, cesium-134 (134Cs), cesium-137 (137Cs), and iodine-131 (131I). The data comes from the analysis of particulates accumulated in filter media, drawn by high-volume air samplers fixed in the field. Such data is typically dominated by natural radionuclides, such as 7Be and 210Pb. 7Be is a natural cosmogenic radionuclide that is produced in the upper atmosphere when cosmic rays bombard oxygen and nitrogen. 210Pb is also a natural radioisotope that results from the decay of uranium (238U) to radium (226Ra). 238U comes from the soil and eventually decays to 210Pb. Radon-222, which is a natural radioactive gas, is also a part of this decay chain. Radon moves through the soil and becomes diluted in the atmosphere. If a home is built on soil or rocks that contain uranium, radon can seep into homes and may accumulate to high levels. More information about the Health Canada radon program can be found on the Health Canada website. For all our stations, the airborne radioactivity data shows a small increase in the activity concentration of 134Cs, 137Cs and 131I measured between March and May of 2011, attributable to the nuclear accident at the Fukushima-Daiichi Nuclear Power Station. It is important to note that, even at their respective peaks, the measured activity concentrations of 134Cs, 137Cs and 131I represent only a small fraction of typical background exposure from natural sources of radiation. Occasionally, other small increases in activity concentration of anthropogenic radionuclides are observed. Spikes in 137Cs activity are often associated with forest fires, which can lead to the re-suspension of 137Cs already present in the environment, most likely from atmospheric nuclear weapons testing in the 1960’s. Detection of small amounts of 131I is commonly associated with its medical use by hospitals.The map shows the approximate sampling location for each monitoring station.

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.The Guidelines for Canadian Drinking Water Quality recommend a Maximum Acceptable Concentration (MAC) for tritium in drinking water of 7000 Bq/L. The measured activity concentrations of tritium in drinking water are well below this guideline value.The map shows the approximate sampling location for each monitoring station. Stations are found within the associated location range.

The ASTER instrument that was launched onboard NASA’s Terra spacecraft in December 1999 has an along-track stereoscopic capability using two telescopes in its near infrared spectral band to acquire data from nadir and backward views. Over 1.2 million scenes (level-1A products) acquired between March 2000 and August 2008 were used to generate the ASTER Global DEM (ASTGTM) collection.  For more information, please see the metadata link above.

This dataset contains the total annual releases of radionuclides released directly to the environment through stack emissions from uranium and nuclear substance processing facilities in Canada.This original radionuclide releases dataset of the uranium and nuclear substance processing facilities provides results for both stack emissions and direct discharge (i.e. releases to water). The dataset has been divided in two subsets for better discoverability. In this record as its title indicates, you will find the stack emissions results mapped. Make sure to look at the uranium and nuclear substance processing facilities direct discharge record in order to obtain a complete picture.

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.The dataset shows concentrations of airborne radionuclides that were targeted for analysis and detected, for example, Beryllium-7 (7Be), Lead-210 (210Pb), Cesium-134 (134Cs), Cesium-137 (137Cs), Iodine-131 (131I), Xenon-133 (133Xe), and Xenon-135 (135Xe), among others. The data is presented in xml file format, selected to conform to the International Atomic Energy Agency’s (IAEA) International Radiological Information Exchange (IRIX) Format. The IRIX format is used to facilitate the exchange of web-based emergency data and information to help organizations respond to radiological incidents and emergencies.The map shows the approximate sampling location for each monitoring station.
