Radon is a carcinogenic, radioactive gas that can accumulate indoors and undetected by human senses. Therefore, accurate knowledge of indoor radon concentration crucial for assessing radon-related health effects or identifying radon-prone areas.

Radon (222Rn) is a radioactive gas with well-documented harmful effects; the World Health Organization has confirmed it as cancerogenic for humans. These detrimental effects have prompted Europe to establish national reference levels protect exposed population. This reflected in European directive 59/2013/EURATOM, which been transposed into regulations of EU Member States. Specifically, requires identification Priority Areas facilitate remediation regions high Rn levels. The regulation also...

Objectives of measuring radon concentrations are radioprotection, as high in the atmosphere hazardous agents, and scientific applications, mainly related to an environmental tracer. For screening surveying, usually relatively simple monitors used such track-etch or SSNTD detectors, while for research, mostly more sophisticated expensive equipment is employed. some years, a new generation instruments available that were conceived consumer grade monitors; however their performance also usage...

In addition to cheap track-etch and expensive research-grade radon monitors, for several years, a new generation of affordable consumer-grade active monitors has been available. Their performance raises the question whether they could also be used certain objectives in scientific context. This requires particular QA/QC as well understanding their behavior limitations. paper reports experiences with RadonEye acquired over approximately two mainly recording time series concentration indoors...

Indoor radon is a major hazard to human health; it one of the leading causes lung cancer. Therefore, research in Asia has intensified recently due growing awareness harm that poses. An analysis collected literature data showed Asia–Oceania, some regions have—or are believed have—little indoor problems climate and low Rn ground. It can be concluded countries have their own approaches, techniques, protocols. Data were not harmonized within each region; however, measurement techniques compared...

Traditionally, for indoor radon testing, predominantly passive measurements have been used, typically applying the solid-state alpha track-etch method long-term and charcoal short-term measurements. However, increasingly, affordable consumer-grade active monitors become available in last few years, which can generate a concentration time series of an almost arbitrary duration. Firstly, we argue that well be used quality-assured assessment consequent reliable decisions. Secondly, discuss...

Accurate knowledge of indoor radon exposure is vital information for assessing radon-induced health effects, identifying prone areas or estimating the number people affected by exceedance a specific concentration in given area.Large-scale measurement campaigns are usually tool choice determining regional national exposure. These need to be representative terms all relevant factors governing (e.g., geogenic availability, distribution across floor levels, building types) providing an unbiased...

Radon (222Rn) is a radioactive gas considered the major source of ionizing radiation exposure for population and represents significant health risk when it accumulates indoor environments. In Europe regulation has been implemented in order to address issue radon exposure, including pose national reference levels identification so-called Priority Areas (RPAs). Although European directive states that RPAs are defined as those areas where annual average Indoor Concentrations number dwellings...

Brazil is envisaging a large scale plan for indoor radon assessment. Radon levels shall be mapped and priority areas identified. Given the size of country its diversity in natural socio-economical respects, this challenging project. Pilot studies local surveys have been performed past but no country-wide assessment exists. In November 2023, IAEA organized workshop on survey planning Poços de Caldas, Minas Gerais, Brazil, to support The objective was identify items which resolved...

Ambient dose rate surveying has the objective, in most cases, to quantify terrestrial radiation levels. This is true particular for Citizen Monitoring projects. Readings of detectors, which do not provide spectrally resolved information, such as G-M counters, are sum contributions from different sources, including cosmic radiation. To estimate component, one subtract remaining ones. In this paper, we investigate response two monitors, bGeigie Nano been used extensively Safecast project and...

Consumer-grade economical radon monitors are becoming increasingly popular in private and institutional use, the contexts of both Citizen Science traditional research. Although originally designed for screening indoor levels view regulation decisions about mitigation or remediation—motivated by health hazard posed high concentrations—researchers exploring their potential some environmental studies. For long time, has been used as a tracer investigating atmospheric transport processes. This...

<p>Exposure to indoor radon (Rn) is recognized as a health hazard which may cause several 100,000 lung cancer fatalities per year world-wide. Physical causes are Rn generation part of the decay chains that originate in ubiquitous uranium and thorium its transport through natural built environment, where it can infiltrate air. Generation constitute geogenic hazard. Its geographical distribution reflects ones properties media processes occur, namely their geochemistry physical...

Radon abatement policy is the response to detrimental effect of indoor radon which estimated cause hundred thousands lung cancer fatalities worldwide annually. The consists decisions implement measures. Decisions rest on data and (sometimes competing) interests, among them health protection. Its weight as an argument depends, other factors, knowledge about its subject – in this case, levels, effects, geographical distribution exposure radon. Therefore, quality assurance depends one...

Radon (222Rn) is a radioactive gas considered the major source of ionizing radiation exposure for population and several epidemiological studies provided evidence its detrimental effects on human health. As consequence, World Health Organization classified this as second cause lung cancer after cigarettes smoking. A significant fraction can be attributed to indoor Rn exposure, i.e. houses workplace. In particular, Indoor Concentration (IRC) product Geogenic Potential (GRP), conceptualised...

Radon is a carcinogenic, radioactive gas that can accumulate indoors. Therefore, accurate knowledge of indoor radon concentration crucial for assessing radon-related health effects or identifying radon-prone areas. Indoor at the national scale usually estimated on basis extensive measurement campaigns. However, characteristics sample often differ from population due to large number relevant factors control such as availability geogenic floor level. Furthermore, size does not allow estimation...

Abstract Ambient dose rate surveys reveal zones of an elevated rate. As the observation results from two physical processes—the ‘true’ process in nature that one wants to assess and consists measuring under certain conditions—an observed anomaly can have its cause either process. Anomalous effects rooted are called spurious. Distinction between true spurious anomalies may not be straightforward many cases. example, surveying using a specific instrument is discussed, whose analysis shows...
