This dataset contains the total annual releases of radionuclides released directly to the environment through direct discharge (i.e. releases to water) from facilities operated by Canadian Nuclear Laboratories in Canada.This original radionuclide releases dataset of the Canadian Nuclear Laboratories provides results for both stack emissions and direct discharge. The dataset has been divided in two subsets for better discoverability. In this record as its title indicates, you will find the direct discharge results mapped. Make sure to look at the Canadian Nuclear Laboratories stack emissions record in order to obtain a complete picture.Regulatory Oversight Report for Canadian Nuclear Laboratories Sites - 2018: https://nuclearsafety.gc.ca/eng/resources/publications/reports/regulatory-oversight-reports/cnl-report-2018.cfm

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. Stations are found within the associated location range.

This dataset contains the total annual releases of radionuclides released directly to the environment through direct discharge 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 direct discharge results mapped. Make sure to look at the uranium and nuclear substance processing facilities stack emissions record in order to obtain a complete picture.

The objective of the Independent Environmental Monitoring Program (IEMP) is to build Indigenous and public trust in the Canadian Nuclear Safety Commission's (CNSC) regulation of the nuclear industry, via an independent, technical and accessible environmental sampling program around nuclear facilities, while using CNSC resources effectively and efficiently.

On July 6, a train of 72 cars, carrying 100 tons of crude oil each, exploded in Lac-Mégantic. A high-resolution aerial photograph was collected by Aéro-Photo after the train derailment. This aerial photograph was provided and georeferenced by Aéro-Photo (1961) inc. Purpose: This aerial photograph makes it possible to identify the impact radius of the accident. The image web service (WMS) is offered as an open service. However, to obtain the raw image, please contact Aéro-Photo (1961) inc.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Terrestrial gamma dose rates, reported as ambient dose equivalent in the unit nSv/hr, are presented for the past ninety days to present. Data is measured in real-time, typically from the spectroscopic dosimeters of the Fixed Point Surveillance (FPS) Network. Dosimeter stations of this network are located in population centres and other strategic locations across Canada. Real-time data provides insight into typical levels and fluctuations of radioactivity in the Canadian environment and may provide early detection of sources of radioactivity other than environmental background.As a reference, the Nuclear facilities and uranium mines and mills can be found in the Open Maps catalogue and added to the Real-time Environmental Radioactivity Monitoring map using the "+" (Add layer) button of the viewer’s “Layers” panel. The ESRI REST or WMS links found in the Nuclear facilities and uranium mines and mills metadata record is what’s needed to proceed.

This includes uranium mines and mills, uranium processing facilities, nuclear power plants, research reactors, particle accelerators, and nuclear substances processing facilities. All of these facilities are licensed by the CNSC and are subject to strict regulatory oversight to ensure the safety of the public and the environment.
