In seismically active regions like Utmah, Yemen, geological factors may elevate radon levels in water, requiring monitoring. This study analyzed radon concentrations in groundwater and surface water used for drinking, domestic purposes, and irrigation in Utmah Nature Reserve, Dhamar Governorate, Yemen. Thirty-four water samples were collected: 14 surface water samples (depth &lt;15 m) and 20 groundwater samples (depth 110–320 m) from Al-Azraa and Tahayjer. Radon and radium were measured using CR-39 nuclear track detectors. Results showed surface water radon levels ranged from 0.09 ± 0.03 to 0.25 ± 0.03 Bq/L (average 0.17 ± 0.04 Bq/L), while groundwater levels were higher: 0.20 ± 0.03 to 0.52 ± 0.09 Bq/L (average 0.34 ± 0.06 Bq/L), well below the international safety standard of 11.1 Bq/L set by the U.S. Environmental Protection Agency (EPA). Annual radiation exposure from surface water (inhalation/ingestion) ranged from 0.23 ± 0.08 to 0.64 ± 0.08 μSv/year (average 0.43 μSv/year). Groundwater exposure was higher: 0.50 ± 0.08 to 1.33 ± 0.23 μSv/year (average 0.86–0.87 μSv/year), still below the World Health Organization (WHO) limit (100 μSv/year). The analysis revealed that depth plays a role in radon distribution, with variations observed between surface and groundwater samples. This is likely influenced by geological characteristics or seismic activity in the area. The findings suggest that water sources in the studied locations do not pose significant radiological health risks due to radon exposure. This research highlights the urgent need for ongoing radon monitoring, especially in seismically active regions. The study provides valuable insights into the potential health impacts of radon in drinking water, contributing to improved international health and safety practices.</div></div>","PeriodicalId":16920,"journal":{"name":"Journal of Radiation Research and Applied Sciences","volume":"18 3","pages":"Article 101639"},"PeriodicalIF":1.7,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144098938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary problems in inaccurate lesion segmentation are variation of lesion conditions, lesion irregularity and presence of similarity between lesion regions. To avoid these problems, the Optimized Deep Learning model named as OVGGNet is proposed for the accurate lesion segmentation of medical images. Different data sources are used to collect different kinds of medical images that are preprocessed to enhance contrast of the medical images. The contrast enhanced images are predicted from this preprocessed stage, and then the Dilated dense VGG19 (DDVGG19) model is employed to extract global and local features from the enhanced images. In the feature extraction stage, the Shi Tomasi Corner detector is applied for shape identification and the linear dimensionality reduction approach is applied for undesired information removal. The Optimized Color Feature (OCF) operation is included at the final lesion segmentation tasks to carry out the different kinds of segmented output. Finally, the mapped images are predicted by fusing original and segmented images and its visual representations are provided in the experimental validation. The numerical and graphical validations are conducted to find the optimal performances during lesion segmentation of medical images. The significant performance measures such as segmentation accuracy and Dice Similarity Coefficient index (DSC) achieved performances of 98.81 % and 96.4 % respectively.
