Effects of Meteorological Conditions on the Results of Aerial Radiation Reconnaissance in the Arctic

The real and hypothetical sources of radioactive contamination in the Arctic are considered. The urgency of assessing radiation conditions in the region is shown. The main reasons for reducing the reliability of results of aerial radiation reconnaissance in the Arctic are identified. The statistical distribution of pressure, temperature and moisture content of air over the Arctic is analyzed. The limits are calculated of the relative measurement error of the dose rate reduced to a height of 1 m above the radioactively contaminated area at various heights and caused by the lack of consideration of the influence of meteorological conditions.
