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":""},"PeriodicalIF":0.8,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","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":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, during PEV operation, the inverter system, as the key power conversion device, generates strong electromagnetic field in the local space. Long-term exposure to such electromagnetic environments may have potential effects on human body. In this study, the electromagnetic environment model of the PEV body, human body and simplified inverter is established. The finite element software, COMSOL Multiphysics, is used to calculate and analyse the variations in the induction field in different tissues of the driver and rear passenger, caused by the electromagnetic field generated by the inverter system operating at maximum power. The electromagnetic exposure level of the driver and rear passenger is assessed. Results show significant differences in the electromagnetic exposure levels of different seating positions in the vehicles. The electromagnetic exposure level in the driver's body is higher than that of the rear passenger, but it does not exceed the exposure limits defined by the International Commission for Non-ionizing Radiation Protection. This finding effectively complements the study on evaluating the safety of the electromagnetic environment of PEV and improves public awareness.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":" ","pages":"270-283"},"PeriodicalIF":0.8,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477090","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}

We meticulously analyzed the amount of radioactive effluents discharged from the Hanbit NPPs and their resulting doses to the public for a decade (2014-23). Carbon-14, which accounted for only 1.90% of the total activity in radioactive effluents, contributed 88.53% of the annual effective doses to the public. This impact was significantly larger than that of tritium, which constituted most of the radioactive effluents. We propose potential improvements for the environmental monitoring system, including an increase in monitoring points and cycles of the seawater and seabed sediments to consider the characteristics of oceanic dispersion and the implementation of a radioactivity analysis of carbon-14 in ingestion and respiration-related environmental samples.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":" ","pages":"284-296"},"PeriodicalIF":0.8,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143493242","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}

To determine whether thermal neutron spectra can influence RBE, the RBE of reactor-derived thermal neutrons of average energy 31 meV was evaluated in human peripheral blood lymphocytes using two classical DNA double-strand break endpoints: the dicentric chromosome assay (DCA) and the cytokinesis-block micronucleus assay. Dose-response curves for 41 to 408 mGy revealed a preference for linear regression. Maximum RBE (RBEM) values of 6.7 ± 0.9 and 4.4 ± 0.7 were calculated for the DCA and the micronucleus assay, respectively. These 31 meV RBEM values were significantly lower than our prior results for 64 meV thermal neutrons, which yielded a DCA RBEM of 11.3 ± 1.6 and a micronucleus RBEM of 9.0 ± 1.1. Dose-specific RBE values decreased with increasing dose for both assays. Microdosimetry simulations demonstrated similar quality factor values for both thermal neutron spectra. Dose deposition differences on the cellular scale, the difference in dose rate between irradiation configurations, or a not-yet understood phenomenon may be responsible for the RBE difference between the 31 and 64 meV thermal spectra. These findings indicate that the currently accepted radiation weighting factor wR value of 2.5 for thermal neutrons may underestimate the radiation detriment to small or shallow tissue targets including the lens of the eye.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":" ","pages":"297-313"},"PeriodicalIF":0.8,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11926985/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143586496","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}

Brick samples (S) taken from surface soil production line (5-50 cm) and (D) taken from deep soil production line (50-300 cm) were collected from those factories. The average values of the activity concentrations of 238U, 232Th, and 40K for the brick samples obtained from the surface soil are (19.9 ± 1.5), (47 ± 2.8), and (365.8 ± 6.7) Bq/kg respectively, while the average values of the deep soil reached 18 ± 1.5, 41.7 ± 2.7, and 352.4 ± 6.61 respectively. Also, radiological hazards including Radium equivalent activity (Raeq), absorbed dose rate (DR), indoor and outdoor annual effective dose (AEDEindoor and AEDEoutdoor), and excess lifetime cancer risk (ELCRindoor) were calculated. The results of activity concentrations were within the permissible limits, except for the concentrations of 232Th, also there was a variation in the measurements between the brick production lines using surface and deep soil. The results of radiological hazards were within the limits allowed by the United Nations Scientific Committee on the effects of atomic radiation, except for the DR and ELCRindoor, for some samples, which pose a risk to users because high concentrations of 232Th in certain samples lead to elevated corresponding radiological indices, further research is needed to link these levels to cancer incidence conclusively. Therefore, it is recommended to adopt precautionary measures in factories with increased values to mitigate potential risks.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":" ","pages":"261-269"},"PeriodicalIF":0.8,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477091","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}
