Estimation of indoor retrospective radon concentration is a subject of primordial interest concerning cause-effect studies on the incidence of radon in public health. These studies can be performed by measuring the surface concentration of the radon progeny implanted on mirrors.
The conversion factor (relationship between the concentration of Po-210 on mirrors and the retrospective...
Noble gas systems were developed for use under the Comprehensive Nuclear-Test-Ban Treaty (CTBT) at 40 of the 80 CTBT-specified radionuclide stations within the International Monitoring System (IMS). Operated technologies use HPGe and beta-gamma coincidence-based detection systems.
Noble gas systems process air to extract and measure the radioactive isotopes of xenon that are most likely to be...
ABSTRACT
To meet the need for rapid monitoring of gas activity in Kr-85, Xe-127, Xe-133 and Rn-222, two gamma-ray spectrometers of LNHB have been specifically calibrated with two types of reference containers with respective volumes 500 cm$^3$ and 100 cm$^3$. Two standardization methods were used depending on the radionuclide of interest. For Kr-85, Xe-133 and Xe-127, the reference values...
