Radon gas mapping for environmental assessment in Dessie, Ethiopia.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The geological formations of Dessie town contain rocks that release radon gas, the second leading cause of lung cancer after smoking. To date, there have been no investigations of geology-based radon health risks in Dessie town. The main objective of this study was to evaluate and map the temporal and spatial distribution of radon gas concentrations within Dessie town. The evaluation and mapping were done using advanced geological and geospatial techniques, employing Quantum Geographic Information Systems (QGIS) software to integrate the research area's weather conditions and geological data using shape files for the study area and masking with its geological map. Geological analysis helps to know whether the geological formation of Dessie town is composed of basaltic rocks, as shown on the geological map of Dessie town, which was obtained from the Ethiopian Geological Institute. Based on these geological formations and geospatial analysis, radon gas activity concentrations were estimated in two different ranges: from 3[Formula: see text]for the emanation coefficient 0.3 and from [Formula: see text]for the emanation coefficient 0.1 for this study area. The radon gas distribution map indicates radon levels in Dessie town fall into two ranges, each with its own potential hotspots, as shown by circles of different colors on the map. These results indicate that there exist health-related problems at nine stations due to prolonged exposure to radon gas, and for further investigation of radon gas activity concentrations and their health impact, we recommend experimental measurements provide more accurate results.
