This dataset provides the results obtained by Health Canada’s Radiological Monitoring Network (CRMN) for airborne radioactivity content at monitoring stations wideness Canada.Increasinglyinformation well-nigh the CRMN network can be found here. The results provided are worriedness 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 wringer of particulates piled in filter media, drawn by high-volume air samplers stock-still 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 undercurrent when cosmic rays bombard oxygen and nitrogen. 210Pb is moreover a natural radioisotope that results from the waste of uranium (238U) naturally present in the ground. An important intermediate step of uranium waste is radon. Radon is a naturally occurring radioactive gas that moves through the soil and becomes diluted when mixed with outdoor air. Radon represents tropical to 50% of radioactivity exposure for most Canadians considering it can yaffle in indoor environments, sometimes to upper levels. 210Pb is present in the CRMN air filters considering radon sooner decays to 210Pb, with several intermediate steps.Increasinglyinformation well-nigh Health Canada’s National Radon Program can be found here. For all our stations, the airborne radioactivity data shows a small increase in the worriedness concentration of 134Cs, 137Cs and 131I measured between March and May of 2011, owing to the nuclear wrecking at the Fukushima-Daiichi Nuclear Power Station. It is important to note that, plane at their respective peaks, the measured worriedness concentrations of 134Cs, 137Cs and 131I represent only a small fraction of typical preliminaries exposure from natural sources of radiation. Occasionally, other small increases in worriedness concentration of anthropogenic radionuclides are observed. Spikes in 137Cs worriedness are often associated with forest fires, which can lead to the re-suspension of 137Cs once present in the environment, most likely from atmospheric nuclear testing in the 1960’s. Detection of small amounts of 131I is wontedly associated with its medical use by hospitals.
