During the course of an investigation into domestic radon levels in Northamptonshire, two hourly sampling real-time radon detectors were operated simultaneously in separate locations 2.25 km apart in Northampton, in the English East Midlands, for a 25-week period. This period of operation encompassed the period in September 2002 during which the Dudley earthquake (magnitude - 5.0) and smaller aftershocks occurred in the English West Midlands, UK. We report herein our observations regarding the occurrence of simultaneous short-period radon anomalies and their timing in relation to the Dudley, and other, earthquakes which occurred during the monitoring period. Analysis of the radon time-series reveals a short period when the two time-series displayed simultaneous in-phase short-term (6-9 h) radon anomalies prior to the main Dudley earthquake. Subsequent investigation revealed that a similar period occurred prior to another smaller but recorded earthquake in the English Channel.

Article Synopsis
- A new study presents an early warning system for radon exhalation rates by combining a VMD-GRU prediction model with similar day analysis for improved safety and reliability.
- The Variational Mode Decomposition (VMD) algorithm breaks down radon data into various components, which are then forecasted using the Gated Recurrent Unit (GRU) algorithm before being aggregated for an overall estimate.
- The VMD-GRU model's effectiveness is supported by comparisons with other models, showing significant improvements in detecting anomalies in real time, thereby enhancing decision-making for radon monitoring.
Utilization of radiometric data for mapping primary and secondary sources of gamma radiation and radon/thoron release potentials in Ireland.

Background: This paper presents a novel approach to predict and map radon and thoron levels. We developed separate radon and thoron prediction maps for Ireland and introduced a system for producing high-resolution 3D radiation maps which may be used for planning purposes in residential areas, recycling and demolishing waste depots, and quarries of building and construction material. Additionally, we highlight the critical need to monitor thoron alongside radon in indoor surveys, as thoron's shorter half-life and higher energy levels may pose a greater health risk.

Article Synopsis
- The study monitored radon (Rn) concentrations in groundwater over 12 years (2012-2023) at eight sites in the Baikal region, showing variations between 30% to 60% of average levels (15 Bq/l, 30 Bq/l, and 50 Bq/l).
- Cluster analysis indicated a strong connection between two subgroups of data due to similar groundwater discharge mechanisms, while Fourier analysis identified significant cycles linked to air temperature, pressure, and groundwater discharge.
- The research also found that radon anomalies correlate with seismic activity, suggesting that these anomalies can act as precursors for earthquakes, leading to a predictive model for radon variations in groundwater with 80% average efficiency.

Unlabelled: Climate change and formation of regional weather features increase both direct (immediate effects of extremal temperature and other weather and climatic anomalies) and indirect (environmental deterioration, etc.) consequences of global climate change. The development of investigations of medical weather assessment, medical and meteorological forecasting system, the use of treatment and preventive measures give the opportunity to prepare for weather biotropic conditions and reduce weather-conditioned exacerbations.

Various anomalies occurring before earthquakes are currently being studied to predict seismic events, with one of them being the radioactive element radon (Rn). Radon concentrations in the soil, water, and atmosphere fluctuate in response to crustal movement. Recent research has statistically detected anomalies by analyzing the fluctuations in radon concentrations before earthquakes and conducting quantitative evaluations of radon.
