Consistency test of coincidence-summing calculation methods for extended sources
(Applied Radiation and Isotopes, 2020)
An internal consistency test of the calculation of coincidence-summing correction factors FC for volume sources is presented. The test is based on exact equations relating the values of FC calculated for three ideal ...
Response of TL and OSL passive personal dosimetry systems in poly-energetic and multi-directional photon radiation fields
(Applied Radiation and Isotopes, 2019)
The aim of this paper is to examine the energy and angular responses of thermoluminescent dosimeters containing either MTS-N (LiF:Mg,Ti) or MCP-N (LiF:Mg,Cu,P) detector materials, and of the InLight optically stimulated ...
Liquid scintillation counter calibration approach for 90Sr detection and testing performance of TK100 resin
(Applied Radiation and Isotopes, 2019)
90Sr detection efficiency determination was applied for liquid scintillation counting (LSC) by computing a model for the relation between detection efficiency and the time passed since radiochemical separation. This allowed ...
Small dose effect in RADFET with thick gate oxide
(Applied Radiation and Isotopes, 2019)
In order to track “small dose effect” leading to stabilization of RADFETs with 1 μm thick oxide fabricated at Tyndall National Institute, Cork, Ireland irradiation was performed with gamma-rays in the radiation dose interval ...
Radon measurements using open-faced charcoal canisters - Measurement uncertainty and method optimization
(Applied Radiation and Isotopes, 2020)
Open-faced charcoal canisters have been used for radon measurements for over 40 years. This method is sensitive to temperature, changing radon concentrations, humidity and other parameters, but a comprehensive study dealing ...
Optimization of the radiolabelling method for improved in vitro and in vivo stability of 90Y-albumin microspheres
(Applied Radiation and Isotopes, 2020)
Biologically stable 90Y-labelled albumin microspheres (AMS) were developed by optimizing the process of their preparation. Three formulations of 90Y-AMS were initially prepared with high radiolabelling yield but depending ...
Determining the probability of locating peaks using computerized peak-location methods in gamma-ray spectra as a function of the relative peak-area uncertainty
(Applied Radiation and Isotopes, 2020)
The probabilities of locating peaks with a high relative peak-area uncertainty were determined empirically with nine types of peak-location software used in laboratories engaged in gamma-ray spectrometry measurements. It ...
Systematic influences on the areas of peaks in gamma-ray spectra that have a large statistical uncertainty
(Applied Radiation and Isotopes, 2018)
A method is presented for calculating the expected number of counts in peaks that have a large relative peak area uncertainty and appear in measured gamma-ray spectra. The method was applied to calculations of the correction ...
