“…The AlphaGUARD is the most popular portable device with a low-effective volume for radon measurement. Mazed et al (2007) reported that the time needed to measure 200 Bq m −3 with the AlphaGUARD was 15 min ( 5 ) . Based on that the counts needed to measure with the AlphaGUARD is equivalent to 150 counts.…”

AlphaGUARD is a low-effective volume detector and one of the most popular portable radon monitors which is currently available. This study investigated whether AlphaGUARD can accurately measure the variable indoor radon levels. The consistency of the radon-concentration data obtained by AlphaGUARD is evaluated against simultaneous measurements by two other monitors (each ~10 times more sensitive than AlphaGUARD). When accurately measuring radon concentration with AlphaGUARD, we found that the net counts of the AlphaGUARD were required of at least 500 counts, <25% of the relative percent difference. AlphaGUARD can provide accurate measurements of radon concentration for the world average level (~50 Bq m−3) and the reference level of workplace (1000 Bq m−3), using integrated data over at least 3 h and 10 min, respectively.

“…To assess indoor Radon concentration, it is fundamental to estimate the concentration of Radon in buildings and dwellings [82]. Radon meters make it possible by counting the impacts of α particles and then computing the number of impacts and the duration of the measurement, to determine the concentration of Radon in the air, expressed in Bq•m −3 [83]. It has been found that the Radon level in buildings is also very variable.…”

The explosive data growth in the current information age requires consistent new methodologies harmonized with the new IoT era for data analysis in a space–time context. Moreover, intuitive data visualization is a central feature in exploring, interpreting, and extracting specific insights for subsequent numerical data representation. This integrated process is normally based on the definition of relevant metrics and specific performance indicators, both computed upon continuous real-time data, considering the specificities of a particular application case for data validation. This article presents an IoT-oriented evaluation tool for Radon Risk Management (RRM), based on the design of a simple and intuitive Indoor Radon Risk Exposure Indicator (IRREI), specifically tailored to be used as a decision-making aid tool for building owners, building designers, and buildings managers, or simply as an alert flag for the problem awareness of ordinary citizens. The proposed methodology was designed for graphic representation aligned with the requirements of the current IoT age, i.e., the methodology is robust enough for continuous data collection with specific Spatio-temporal attributes and, therefore, a set of adequate Radon risk-related metrics can be extracted and proposed. Metrics are summarized considering the application case, taken as a case study for data validation, by including relevant variables to frame the study, such as the regulatory International Commission on Radiological Protection (ICRP) dosimetric limits, building occupancy (spatial dimension), and occupants’ exposure periods (temporal dimension). This work has the following main contributions: (1) providing a historical perspective regarding RRM indicator evolution along time; (2) outlining both the formulation and the validation of the proposed IRREI indicator; (3) implementing an IoT-oriented methodology for an RRM indicator; and (4) a discussion on Radon risk public perception, undertaken based on the results obtained after assessment of the IRREI indicator by applying a screening questionnaire with a total of 873 valid answers.

“…Most existing methods of alpha-active nucleus monitoring involve either laboratory analysis of field samples or direct detection of alpha-particles (Nava et al, 2004;Mazed et al, 2007;Manchanda et al, 1990), that implies direct contact with contaminated surfaces. These methods fail to ensure complete and rapid examination of a territory or an object due to many laborconsuming measurements.…”
