The Canadian Radiological Monitoring Network – Tritium in Atmospheric Water Vapour
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.
The Canadian Radiological Monitoring Network – Monitoring Stations
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. The CRMN has been operating since 1959, and is used to establish long-term trends in naturally occurring environmental radioactivity, nuclear weapons fallout, as well as radioactivity generated by other human activities including nuclear power generation and medical isotope production. Full datasets for the Canadian Radiological Monitoring Network are available on the Open Government Portal.The Fixed Point Surveillance System (FPS) is an integrated network of radiation detectors providing terrestrial gamma radiation measurements in real time. The detectors are located in every province and territory of Canada with larger numbers in the vicinity of major Canadian nuclear facilities and ports where nuclear powered vessels sometimes harbour. Almost real time measurements are available on the EURDEP (EUropean Radiological Data Exchange Platform) website and monthly summaries are provided on the Health Canada website. The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is a universal arms control treaty that bans all States from conducting nuclear explosions in any environment (atmosphere, underground, underwater). Canada is a signatory to the United Nations CTBT. The Radiation Protection Bureau of Health Canada is responsible for four certified radionuclide monitoring stations and a certified radionuclide laboratory. Additional information on the CTBT is available on the CTBTo website.The map shows the approximate sampling location for each monitoring station. Stations are found within the associated location range.
Influenza/Influenza-like Illness Activity - Current Week
FluWatch is Canada's national surveillance system that monitors the spread of flu and flu-like illnesses on an on-going basis.Activity Level surveillance is a component of FluWatch that provides an overall assessment of the intensity and geographical spread of laboratory-confirmed influenza cases, influenza-like-illness (ILI) and reported outbreaks for a given surveillance region. Activity Levels are assigned and reported by Provincial and Territorial Ministries of Health. A surveillance region can be classified under one of the four following categories: no activity, sporadic, localized or widespread.For a description of the categories, see the data dictionary resource. For more information on flu activity in Canada, see the FluWatch report.(https://www.canada.ca/en/public-health/services/diseases/flu-influenza/influenza-surveillance/weekly-influenza-reports.html)Note: The reported activity levels are a reflection of the surveillance data available to FluWatch at the time of production. Delays in reporting of data may cause data to change retrospectively.
Hydrometric Monitoring Stations
A station is a site on a river or lake where water quantity (water level and flow) are collected and recorded.
Temperature sensor point
Temperature data (typically in time series format) comes from investigations performed by government agencies, geotechnical engineers and consultants, academics, and others to obtain information on the air or ground thermal conditions of a site. Ground temperature investigations generally include the installation of temperature sensors at a variety of depth intervals, and data loggers which record the temperatures at regular time intervals ( e.g., hourly or daily) for varying time periods ranging from one-time or occasional measurements to multi-year monitoring. They also often involve the installation or monitoring of above-ground weather stations. Where ground temperature data characterizes the ground thermal regime, weather data allows for an understanding of the relationship between the ground thermal regime and local weather.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .
