The Canadian Radiological Monitoring Network – Environmental Dosimetry The Canadian Radiological Monitoring Network – Environmental dosimetry 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 here: http://www.hc-sc.gc.ca/ewh-semt/contaminants/radiation/crmn-rcsr/index-eng.php. This background radiation data contains both “monitoring” and “transit” dosimeters starting in 2015. The historical background radiation dose data can be found here: http://open.canada.ca/data/en/dataset/dc69b741-bcd4-4e0c-a3d3-f25bf9f34f03. A transit dosimeter is sent along with the monitoring dosimeter to determine if there is a significant dose recorded by the dosimeter while it is in transit to the sampling station. The transit dosimeter is shipped out with a station monitor, and shipped back with the station monitor from the previous quarter. The monitoring dosimeters are deployed over a longer time (around three months) than the transit dosimeters (around 3 weeks). This difference largely explains the lower recorded dose values for the transit dosimeter. The results provided for the monitoring and transit dosimeters are expressed as absorbed dose calibrated with a cesium source in units of millisieverts (mSv). The accuracy of the dosimeters is estimated to be ± 15%. The external dose can be attributed almost exclusively to natural radiation (of terrestrial and cosmic origin) with fluctuations based on several factors including location, soil characteristics, and seasonal changes. 2016-01-27 2019-10-09 Health Canada open-ouvert@tbs-sct.gc.ca Nature and EnvironmentRadioactivityenvironmental radioactivity monitoringradiation monitoringCanadian Radiological Monitoring NetworkCRMNHealth CanadaRadiation Protection BureauNational Monitoring Sectionbackgroundmonitoringexternal dose Environmental Dosimetry - DataCSV http://health.canada.ca/apps/open-data/crmn/nms_environmental_dosimetry_ssn_dosimetrie_environnementale.csv Environmental Dosimetry - GraphsPDF http://www.hc-sc.gc.ca/data-donnees/hecs-dgsesc/nms_environmental_dosimetry_ssn_dosimetrie_environnementale-eng.pdf Environmental Dosimetry - GraphsPDF http://www.hc-sc.gc.ca/data-donnees/hecs-dgsesc/nms_environmental_dosimetry_ssn_dosimetrie_environnementale-fra.pdf
