Using the scientific information gathered at the time, we have attempted to create the clearest possible picture of this event. Although scientific knowledge has advanced since then, the overall assessment remains unchanged. An important lesson to be drawn from this crime is the significance of taking early actions to identify the level of exposure and ensure timely intervention to minimize the consequences for the victim.

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.</p>","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}

Major sources include vehicular emissions, industrial activities, agricultural burning, and transboundary haze. 7Be and 210Pb are tracers for studying aerosol behavior. Aerosol samples were collected using a high-volume air sampler, cascade impactor, and rainwater from the rooftop of Building No.16 (34.71° N, 135.64° E) at Osaka Sangyo University. Results showed that 7Be and 210Pb-carrying aerosols were mainly attached to aerosols smaller than 2 μm, peaking at 0.33-0.55 μm. This study reports the world's first simultaneous measurement of the activity size distribution of 7Be and 210Pb-carrying aerosols across the entire aerosol particle size range, including the smallest sizes. A strong correlation between 7Be and SO42- concentration and between 210Pb and SO42- concentration in summer 2020 suggests SO42-as their carrier.
