Bei der Umsetzung dieses Messverfahrens bestehen jedoch bei den Betroffenen zum Teil Unsicherheiten, die insbesondere auf bisher fehlende, praxisnahe Anwendungsstra-tegien zurückzuführen sind. Mobile in situ gamma spectrometry is an important instrument in the emergency preparedness for nuclear accidents. This work contributes through the development of strategies and analysis methods for two applications: an on-line search for gamma-emitting orphan sources and on-line estimation of the depth distribution of 137Cs.

Portable gamma spectrometers were placed in concentric circles around a reference point. A three-story concrete building and a few low structures were Title: Intercomparison of In Situ Gamma Ray Spectrometers Created Date: 19990709113147Z ISO 18589-7:2013 specifies the identification of radionuclides and the measurement of their activity in soil using in situ gamma spectrometry with portable systems equipped with germanium or scintillation detectors.

Die In-situ-Gammaspektrometrie gewinnt in Freigabeverfahren nach § 29 StrlSchV, insbesondere für Freimessungen von Gebäuden, immer mehr an Bedeutung. Bei der Umsetzung dieses Messverfahrens bestehen jedoch bei den Betroffenen zum Teil Unsicherheiten, die insbesondere auf bisher fehlende, praxisnahe Anwendungsstra-tegien zurückzuführen sind.

The improved method is faster, safer, and better at quantifjmg soil concentrations of radionuclides than the method that has been in use. The calibration methods for in-situ gamma spectrometry systems used CIEMAT include semiempirical approaches using point sources, pure mathematical calibrations using the ISOCS software and a stripping method developed at CIEMAT. The two first procedures give information about the activity concentration in the soil, and the third method provides distributions of dosimetric quantities as a Five teams from the Nordic countries utilising a range of in-situ measurement equipment spent 5 days making a series of measurements at a number of pre-selected and pre-characterised sites varying in terms of contamination density, topography, pedological properties etc. Detailed information was available as to contamination density, depth distribution, soil characteristics etc.

The experiences gained with these Made available by U.S. Department of Energy Office of Scientific and Technical Information 2011-06-01 Gamma Spectroscopy is the science (or art) of identification and/or quantification of radionuclides by analysis of the gamma-ray energy spectrum produced in a gamma-ray spectrometer. Learn more about this widely used technique in environmental radioactivity monitoring, nuclear medicine and radiopharmaceuticals, health physics personnel monitoring Following a nuclear accident, in situ gamma spectrometry is a powerful method for rapid evaluation of the gamma activity deposited onto the soil surface as well as the surficial contamination of flat objects. Subjects. General (13.080.01) Radiation measurements (17.240) Buy this standard Gamma spectroscopy detectors are passive materials that wait for a gamma interaction to occur in the detector volume.

TÜV Süddeutschland, Westendstr. 199, Munich, Germany In the Technical Series #334 (1992) the IAEA stated, that especially for large areas e.g. outside In situ gamma spectrometry is a rapid and accurate technique to assess the activity concentration of gamma-emitting radionuclides present in the top soil layer or deposited onto the soil surface. This method is also used to assess the dose rates of individual radionuclides. 2011-06-01 · In-situ gamma spec.
