“…Many approaches require destructive tests in which the sample is reduced to powder, dried, poured into a container with a specific geometry and sealed. After a period of about 1 month required for establishing the radioactive equilibrium between

Ra and

Rn (see Figure 2 of [ 7 ]), the sample is positioned inside a thick shielding structure used to reduce the external background and measured with High Purity Germanium (HPGe) [ 8 , 9 , 10 , 11 , 12 , 13 ] or with a higher efficiency NaI spectrometer [ 13 , 14 , 15 ]. The analysis to extract the radionuclide abundances and the ACIs are done offline and manually.…”

In the building material and stones market, lots of restrictions are coming in different world zones. In Europe, a recent regulatory set up the maximum level of radiological emissions for materials intended for use in public and private building structures. For this reason, companies need to have a very efficient radiological measurements system in their production chain, in order to respect all the rules and to be competitive in the world market. This article describes CORSAIR, a Cloud-Oriented Measurement System for Radiological Investigation and Traceability of Stones. Our cyber-physical system consists of sensing nodes network connected to a data collection gateway through LoRaWAN protocol, and interfaces with a centralized cloud application. CORSAIR introduces a fast, repeatable, real-time and non-destructive method to measure radiological emissions and other parameters of each single building material item, uniquely identified by an applied RFID tag. The validity of this system is confirmed by in-situ measurement campaign compared with high-precision laboratory analysis. The results demonstrate the accuracy of the CORSAIR sensor and the possibility to easily integrate it in the company production chain without any change.

Radiological assessment of the environment in expansive territories poses significant challenges due to the complexity of spatial and environmental variables. The aim of this study was to use and present the advantages of a physico-geographical regionalisation methodology to improve the precision and effectiveness of radiological assessments in large areas. The study area was a region of the Polish Carpathian mountains with a territory of 19,600 km2. By integrating geographic information systems (GIS) and radiological data, this research analysed a similarity of environmental attributes (soil type, lithology, mineralogy) and absorbed dose rate (ADR) level from the terrestrial origin for populations. Consistency in terms of the nature and origin of the relief and lithological diversity was a key aspect that distinguished the radiological characteristics. Therefore, consistency was observed at the macroregional level according to physiographic mapping. The study demonstrates the utility of macroregionalisation in capturing spatial ADR heterogeneity and provides a new strategy in radiological monitoring. Graphical Abstract
