In this work, a first trial of method has been developed to estimate the average annual indoor radon activity concentration from three-week short-term measurements using active radon-222 measuring devices, considering relevant influencing parameters. 24 long-term (6 months) and 50 (3 weeks) were carried out in spaces private houses four Austrian federal states between October 2022 July 2023. At same time as measurements, ambient parameters (outside inside temperature, air pressure inside,...
Abstract Purpose Patient-specific dosimetry is required to ensure the safety of molecular radiotherapy and predict response. Dosimetry involves several steps, first which determination activity radiopharmaceutical taken up by an organ/lesion over time. As uncertainties propagate along each subsequent steps (integration time–activity curve, absorbed dose calculation), establishing a reliable quantification essential. The MRTDosimetry project was European initiative bring together expertise in...
A method was developed to estimate the average annual indoor radon activity concentration from three-week short-term measurements using active radon-222 measuring devices, taking into account relevant influencing parameters (season, temperature difference, temporal air pressure gradient, etc.) during measurements. total of 24 long-term (6 months) and 50 (3 weeks) were carried out in spaces private houses four Austrian federal states between October 2022 July 2023. At same time as...
An increasing number of radiopharmaceuticals and proteins are available for diagnosing treating various diseases. The demand existing newly developed pharmaceutical radionuclides is steadily increasing. radiation exposure levels workers in the radiopharmaceutical industry nuclear medicine field closely monitored, specifically their effective dose equivalent dose, leading to question, whether dawn affects occupational level. This development analyzed evaluated with data from German National...
The 4πγ-counting technique is recognized as a powerful primary method for the standardization of radionuclides decaying with abundant gamma emissions. Based on use detector in quasi 4π-geometry, detection efficiency close to 100% and low uncertainty can be achieved thanks summing effect subsequent transitions. Uncertainties have assigned realistic modelling source–detector geometry respect dimensions, density material composition, calculation total counting various emitted radiation,...
An interlaboratory comparison for European radon calibration facilities was conducted to evaluate the establishment of a harmonized quality level activity concentration in air and demonstrate performance when calibrating measurement instruments radon. Fifteen from 13 different countries participated. They represented levels metrological hierarchy: national metrology institutes designated institutes, authorities radiation protection participants universities. The by German Federal Office...
