The measurement performance and characteristics of electronic radon monitors with respect to radiological environmental parameters are investigated. study includes a sample 14 different types devices from nine manufacturers. currently available on the market acquisition costs in low or medium range. For comparison purposes, high-end AlphaGUARD device is included as benchmark for monitors. Significant differences found between tested instrument types. Overall, however, it can be concluded...
Abstract The study compares exposures to the lung caused by inhalation of radon and progeny with doses from external low-LET radiation. For this purpose, cancer risks, lifetime effects radiation detriments chronic exposure in homes workplaces are calculated. calculations apply accepted risk models derived studies on miners residential representative populations ICRP. In addition, comparable performed determine quantities for associated radiation.
In a working age population, constant...
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...
Abstract The epidemiological approach to converting radon exposure effective dose is examined. Based on the definition of dose, conversion obtained from equivalence lung-specific detriment associated with low-LET radiation and exposure. This most reliably estimates per basis data implicitly includes weighting factor required calculate using dosimetric approach, applying biokinetic models. Consistency between results approaches achieved by a about 10 for alpha particles instead current ICRP...
Radon is considered to be the main source of human exposure natural radiation.As stated by World Health Organization, due inhalation indoor radon much greater than one via ingestion water as degasses from during handling.In response these concerns about universal presence radon, environmental assessment studies are regularly commissioned assess public and workers.The credibility such relies on quality reliability analysis well sample representativeness radiological situation.The...
Since 2003, the German Federal Office for Radiation Protection (BfS) has conducted annual interlaboratory comparisons passive radon measuring devices in order to ensure quality of these measurements. Passive which use solid state nuclear track detectors, electrets or activated charcoal can be tested. The exposures are carried out calibration laboratory at BfS. Radon activity concentrations traced back national standard, being established National Institute Physics and Metrology (PTB)....
The population-averaged risk rate and the annual average effective dose due to residential radon in Germany were calculated. calculations based on an epidemiological approach taking into account age- gender-specific lung cancer incidence rates for German population excess relative of 0.16 per 100 Bq·m−3 radon. In addition, estimates adjusted smoking habits determined. whole was estimated with 4.1·10−5 y−1 (95% confidence interval (CI) 1.4·10−5–7.6·10−5 y−1). Residential causes a detriment...
This paper analyses the data having been gathered from interlaboratory comparisons of passive radon instruments over 10 y with respect to measurement accuracy. The accuracy is discussed in terms systematic and random error. analysis shows that error most issued by professional laboratory services can be within a range ±10 % true value. A single has an additional error, which up ±15 for high exposures (>2000 kBq h m(-3)). increases lower exposures. especially applies solid-state nuclear track...
An international comparison of continuous monitors measuring radon activity concentration was performed to validate the traceability European calibration facilities. It carried out by comparing secondary standards used these previous facilities, ranging from 100 Bq·m−3 300 Bq·m−3. Secondary were individually compared a reference device previously calibrated in atmosphere traceable primary standard. The intercomparison organized National Institute for Nuclear, Chemical, and Biological...

In the framework of EMPIR research project Metrology for Radon, a facility was devised that provides stable and traceable atmospheres realization radon activity concentration at high metrological level. The is used to calibrate test devices measuring in air. It enables precise long-term exposures range between 100 Bq/m
Cancer incidence risks, lifetime effects and radiation detriments are determined for the whole population various subpopulations as a result of acute chronic exposure to low-LET radiation, taking into account risk models, procedures representative populations provided by ICRP. The results given solid cancers in different organs, well soft tissue cancer bone marrow. For most sites good agreement is obtained between this study values published with ICRP better than working age population,...
