The objective of this study is to summarize the key impacts of the latest International Commission on Radiological Protection (ICRP) biokinetic model for thorium ore dust intake and to identify model parameters that require further investigation. The dosimetric significance of thorium ore dust exposure has varied widely over time owing to progressive changes in the inhalation dose coefficients. These changes had a significant influence on radiation protection practices in the Western Australian mineral sand industry, including research initiatives and implementation of control measures. Estimated doses to workers exposed to NORM dust have increased because of the most recent ICRP recommendations. Consequently, we highlight the need for future research, especially in relation to appropriate model input parameters specific to the NORM exposure situation and potential studies investigating the health status of past long-term workers.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":" ","pages":"420-431"},"PeriodicalIF":0.8,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12012373/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143773277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of significant levels of radioactivity in drinking water sources poses potential health risks to the public. Consequently, determining the concentrations of gross alpha and gross beta activity in water is essential for ensuring water safety. Thirteen commercially bottled mineral water samples were collected from Moroccan markets and analyzed using the Liquid Scintillation Counting technique, based on the ISO 11704:2018 method. The results show that the activity concentrations range from a minimum below the lower limit of detection to a maximum of 0.21 ± 0.02 and 0.15 ± 0.01 Bq·L-1 for gross alpha and gross beta, respectively. The concentrations of anions and cations are within recommended limits for drinking water. For each sample, the annual effective dose was calculated and lifetime cancer risks were estimated. The levels of the annual effective dose and lifetime cancer risk were all below the World Health Organization's recommended values for drinking water quality.Highlights: ","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":" ","pages":"322-332"},"PeriodicalIF":0.8,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143617047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings revealed seasonal differences in radionuclide releases, with activities of 1.35 × 1015 Bq during the wet season and 4.70 × 1018 Bq in the dry season. Peak ground concentrations of 137Cs in the wet season reached alarming levels of 6.22 × 103 kBq/m2 within 2.14 km of the release point due to deposition processes like rainout and washout. In contrast, the dry season showed 137Cs ground concentrations of 4.88 × 104 kBq/m2, consisting primarily of noble gases. These results emphasize the importance of effective emergency preparedness strategies, including robust monitoring systems, evacuation plans, and public education. By focusing on protective measures informed by total effective dose equivalent assessments, this study highlights the need for proactive approaches to mitigate radiological hazards and enhance community resilience near nuclear facilities.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":" ","pages":"333-350"},"PeriodicalIF":0.8,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143674314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
