Title: High-resolution alpha spectrometry under field conditions – fast identification of alpha particle emitting radionuclides from air samples
Authors: Pöllänen, R. roy.pollanen@stuk.fi, Siiskonen, T.1
Source: Journal of Environmental Radioactivity. Apr2006, Vol. 87 Issue 3, p279-288. 10p.
Subjects: Radioisotopes, Alpha rays, Nuclear accidents, Membrane filters, Spectrometry, Aerosols, Radiochemical analysis
Abstract: Abstract: Alpha particle emitting radionuclides may be released into the atmosphere as a result of a severe nuclear accident, the malevolent use of radioactive material or some other incident. Rapid detection methods are then of crucial importance for carrying out well-timed protective actions. The present paper demonstrates that a method in which an aerosol sample is collected on a filter and directly analysed by high-resolution alpha spectrometry in a vacuum chamber, but without radiochemical sample treatment, is suitable for field measurements. A detection limit of less than 0.1Bqm−3 for 239Pu is achieved assuming 1-h sampling using a glass-fibre filter and 1-h data acquisition. This value is higher than in the case when sampling is performed using a porous membrane filter. A measurement system consisting of standard components is mounted in a vehicle designed for rapid field measurements. [Copyright &y& Elsevier]
