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). 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. The data contains both “monitoring” and “transit” TLDs. Transit TLDs are sent along with the monitoring TLDs to determine if there is a significant dose recorded by the TLD en route to the sampling station. The transit TLD is shipped out with a station monitor TLD, and shipped back with the station monitor from the previous quarter. Note that the monitor TLDs are deployed over a longer time (around three months) than the transit TLD (around 3 weeks); this largely explains the lower recorded dose values for the transit TLD. The results provided for the…
