Radiometric alpha-emitting nuclide fallout estimation

Diurnal variation of radon progeny

“…These measurements can be further used to analyse the spatial and temporal variations of natural radioactivity and especially radon and its short-lived decay products. Monitoring of the concentration of radionuclides in the lower layers of air has been found to correlate with meteorological parameters such as air temperature, humidity, air speed, atmospheric electric field and airflow direction (Garcia-Talavera et al, 2001;Latha, 2003).…”

“…Monitoring the air radioactivity is widely used as an early warning system for nuclear emergencies (Venuti et al, 1990;Ermilov and Yaryna, 1989), stemming from the fact that the fastest natural conveyor of radionuclides is air. In such an emergency, the a-and b-radioactivity due to actinides and fission products, for example from a nuclear fallout, would be detected.…”
