Background: Many different methods are applied for radon mapping depending on the purpose of the map and the data that are available. In addition, the definitions of radon priority areas (RPA) in EU Member States, as requested in the new European EURATOM BSS (1), are diverse. Objective: 1) Comparison of methods for mapping geogenic and indoor radon, 2) the possible transferability of a mapping method developed in one region to other regions and 3) the evaluation of the impact of different mapping methods on the delineation of RPAs. Design: Different mapping methods and several RPA definitions were applied to the same data sets from six municipalities in Austria and Cantabria, Spain. Results: Some mapping methods revealed a satisfying degree of agreement, but relevant differences were also observed. The chosen threshold for RPA classification has a major impact, depending on the level of radon concentration in the area. The resulting maps were compared regarding the spatial estimates and the delineation of RPAs. Conclusions: Not every mapping method is suitable for every available data set. Data robustness and harmonisation are the main requirements, especially if the used data set is not designed for a specific technique. Different mapping methods often deliver similar results in RPA classification. The definition of thresholds for the classification and delineation of RPAs is a guidance factor in the mapping process and is as relevant as harmonising mapping methods depending on the radon levels in the area.

“…This constitutes a mapping of the surface radon activity into space variations of the atmospheric potential at the altitudes of several kilometers. The recent measurements [Kabrt et al 2014] of radon gas activity concentration distributed over a large area can serve as a basis for the searching of the seismic-induced radon anomaly region. As would be expected, the horizontal electric fields and currents occur near the boundary of the abnormal region where the radon concentration changes from the enhanced value to the background one.…”

Possible atmospheric effects associated with pre-seismic variations of atmospheric radon concentration occasionally observed prior to earthquake occurrence are subjected to theoretical study in order to assess their potential effectiveness. Altitude distribution of atmospheric conductivity is examined as a function of radon and aerosol concentrations. Horizontal components of atmospheric electric fields and currents, which can arise near a boundary of seismo-active region, are estimated. We speculated that changes in radon-induced air ionization can have an impact on fair-weather spectra of ULF electric pulsations. Particular emphasis has been placed on hypothesis for correlation between variations of pre-seismic radon activity and upward thermal radiation measured by satellite over the high seismicity regions. This hypothesis is based on assumption that the radon-induced ionization of atmospheric surface layer can trigger water vapor condensation which in turn results in release of the vaporization heat. Our analysis has shown that the upward thermal flux has to be many orders of magnitude lower than that predicted on the basis of this hypothesis.

“…It is very active and soluble in both water and organic materials, and it can be utilized as a tracer for geochemical, geophysical, and geological studies [1][2][3]. However, radon, which is exhaled either directly or indirectly from the surface of soil, water, building materials, rocks, etc., may be harmful to human health if inhaled over a long period of time [4][5][6][7][8]. According to WHO epidemiological surveys, radon is the second leading cause of lung cancer in people, following smoking [9,10].…”

Radon exhaled from rocks, building materials, and soil can be harmful to human health, so it is necessary to measure radon and its exhalation rate. In this paper, a novel method is proposed to simulate radon exhalation from different medium surface by using a solid Rn-222 source, and the radon exhalation rate can be adjusted by replacing radon accumulation chambers with different bottom areas. Firstly, an experiment was done to determine the activity of the Rn-222 source, and then the theoretical radon exhalation rate can be quickly calculated from the relationship between the radon source activity and the bottom area of the radon accumulation chamber. Three sets of comparative experiments were conducted using two radon accumulation chambers with different volumes, respectively. Comparing the average values obtained from the experiments with the calculated theoretical values, it can be obtained that the differences corresponding to the two radon accumulation chambers between the theoretical radon exhalation rates and the experimentally average values are all within 6%. Without replacing the radon source, the radon exhalation rate is inversely varies with the bottom area of the chamber. Therefore, the correctness of adjusting the radon exhalation rate by replacing radon accumulation chambers with different bottom areas to simulate radon exhalation from different media surfaces is verified. This method can be used to calibrate the radon exhalation measuring instruments.
