International audience; When the sample activity is measured for various reasons several times, then with each measurement can be associated an individual decision threshold and limit of detection. Each measurement can be analyzed through its own dec

Emission probabilities of the main γ-rays following the decay of 222Rn and Daughters

Autor: M. Etcheverry, J. Morel, J.-L. Picolo

Publikováno v: Applied Radiation and Isotopes. 49:1387-1391

There has been increasing interest over recent years in methods for measuring the activity of 222 Rn ( T 1/2 =3.8 d). Among these methods, γ -ray spectrometry would appear to be advantageous because the radionuclide activity can be measured directly

Thermal cryogenic detectors (bolometers, microcalorimeters) have been operated in the pulse mode to quantify ionizing radiation. These detectors exhibit considerable promise for applications in high resolution spectrometry and integral counting. A co

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 339:343-348

An international intercomparison of internal proportional gas counting of 85 Kr and 3 H has been carried out under the auspices of EUROMET, a European Collaboration in Measurement Standards. A sample of 85 Kr mixed with inactive krypton gas was measu

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 312:24-33

Two major limitations met in the field of ionizing radiation metrology, i.e. energy resolution and detection energy threshold, may be improved by one or two orders of magnitude by using composite bolometers cooled below 300 mK and operating in the pu

Standardization of 222Rn by LSC and comparison with alpha- and gamma-spectrometry

Autor: P, Cassette, M, Sahagia, L, Grigorescu, M C, Lépy, J L, Picolo

Publikováno v: Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine. 64(10-11)

Liquid scintillation counting (LSC) was used for the measurement of 222Rn in equilibrium with its daughters, with detection efficiency close to 5. The appropriate corrections were considered, including one related to the probability that the 165-micr
