Sampling for Airborne Radioactivity

نویسنده

چکیده

This report examines how to sample airborne radioactivity with minimal complexity and time expenditure, using conventional high-volume samplers in combination with alpha-particle spectrometry. The use of alpha spectrometry provides compensation for radon/thoron decay products collected on the filter paper of the sampler, leading to a seven-fold improvement in measurement sensitivity of artificial airborne alpha sources compared to simply treating radon/thoron products as a background contribution. It is estimated that high sensitivity measurements of airborne radioactivity can be made in under 30 minutes, using the procedures recommended in this report.

Sampling For Airborne Radioactivity

As the nation's industrial complex grows, one of its attendant evils—environmental pollution—grows apace. Perhaps no segment of this complex grows more rapidly at present than the atomic energy industry. Responsible officials are gradually becoming aware of the potential for pollution of this new giant. The problem is complicated by security requirements and by virtue of the inability to sense ...

Environmental radioactivity in the UK: the airborne geophysical view of dose rate estimates.

This study considers UK airborne gamma-ray data obtained through a series of high spatial resolution, low altitude surveys over the past decade. The ground concentrations of the naturally occurring radionuclides Potassium, Thorium and Uranium are converted to air absorbed dose rates and these are used to assess terrestrial exposure levels from both natural and technologically enhanced sources. ...

Monitoring of airborne artificial radioactivity with total beta counting

Both in Finland and in Bulgaria the national weather services started networks for airborne radioactivity monitoring in the late 1950s because of the intense testing of nuclear weapons. Soon the institutes in both countries adopted monitoring methods for airborne total beta activity because these methods are relatively simple and cost-efficient. A comparison of results from Finland and Bulgaria...

Measurements of atmospheric 7Be properties using high-efficiency gamma spectroscopy.

Two 7Be-related properties have been measured using a high-efficiency germanium gamma spectrometer (relative efficiency of 90%), namely, the activity median aerodynamic diameter (AMAD) of 7Be-associated atmospheric aerosols and the airborne 7Be radioactivity. With time resolutions of about 1-3d correlations between these 7Be-related properties and different meteorological parameters were identi...

Occupational exposure of phosphate mine workers: airborne radioactivity measurements and dose assessment.

Under the Egyptian program for radiation safety and control, airborne radioactivity measurements and radiological dose assessment were conducted in some phosphate and uranium mines. Abu-Tartor mine is one of the biggest underground phosphate mines in Egypt. Airborne radioactivity, radon ((222)Rn) and its short-lived decay products (progenies) and thoron ((220)Rn), were measured in selected loca...
