Recent studies involve large numbers of workers and include health outcomes for workers who accumulated moderate (and even high) doses over prolonged periods while employed during the earlier years of the nuclear industry. The interpretation of the findings of these recent studies has proved to be disappointingly difficult. There are puzzling patterns of results involving the period of first employment and monitoring for radionuclide intakes, depending on the particular study examined. Explaining these patterns is crucial for a reliable understanding of results in terms of occupational radiation exposure. In this paper, an updated review of nuclear worker studies is presented in the context of these patterns of results, making use of the latest relevant results. It is apparent that the strikingly raised risks for mortality from solid cancers for workers hired in later years reported from the International Nuclear Workers Study (INWORKS) is effectively confined to workers at five nuclear facilities in the USA, and that the notable variation of risks in INWORKS between workers monitored or not for radionuclide intakes is driven by UK workers. These are the areas where effort must be concentrated before a confident derivation of radiation risk estimates can be obtained from these nuclear worker studies.","PeriodicalId":50068,"journal":{"name":"Journal of Radiological Protection","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143034752","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}

These perceptions contributed to the social challenges faced by the residents of Fukushima at the time, including prejudice and discrimination. This heightened concern about radiation exposure, particularly among younger generations who were considering marriage or starting families. In the present study, we aimed to investigate the present status of radiation risk perception among university students in Japan and the factors associated with radiation risk perception among these students. A questionnaire survey was administered to university students throughout Japan. We collected demographic information as well as queried their perception of radiation risk (delayed health effects and genetic effects). The results showed that approximately 60% and 40% of respondents believed that delayed effects and genetic effects would occur among residents of Fukushima, respectively. Additionally, having a university major other than studying radiation techniques and living in western Japan were associated with these perceptions of risk. In the future, enhancing risk communication, especially among young populations in western Japan, is necessary to dispel anxiety about the risks from radiation exposure.","PeriodicalId":50068,"journal":{"name":"Journal of Radiological Protection","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015120","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}

Research investigations in the 1990s provided greater insight into the characteristics of inhaled thorium ore dust and bioassay studies inferred that some workers had accumulated significant lung burdens of thorium. Recent changes to biokinetic models have increased the radiation dose assessed to arise from thorium intake, raising questions on the appropriateness of current assumptions used in exposure assessment and feasibility of further bioassay research. Past radiation research undertaken in the Western Australian mineral sands industry is summarised and findings from contemporary research relevant to thorium ore dust exposure, thorium health effects and the associated assessment of internal radiation dose are reviewed and analysed. Radiation exposures in the industry have reduced substantially in the last two decades, however current workplace exposure measurement regimes may not reflect the actual intake of monazite-bearing dusts on an individual basis. Past research indicated that thorium associated with monazite dust is relatively insoluble and avidly retained in the lung. There is a paucity of published research on thorium retention and excretion by mine workers over the last 20 years, however significant advances have been made in the detection of thorium in biospecimens. Improvements in measurement technology should make periodic bioassay measurements feasible for selected long-term workers involved in the mining and processing of naturally occurring radioactive materials. Past worker dose estimates require re-evaluation following recent updates to biokinetic models and long-term follow up of the health of workers chronically exposed to thorium ore dusts is recommended.","PeriodicalId":50068,"journal":{"name":"Journal of Radiological Protection","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143025589","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 average overlapping portion was 33.8 ± 12.1 mm, accounting for approximately 7.0% of the total scan length, contributing a dose-length product of 33.4 mGy*cm and an effective radiation dose of 0.5 mSv. Male sex and the total scan length were identified as significant factors influencing overlap (p= 0.002 and < 0.001, respectively). Despite overlapping scans frequently imaging the lower lungs, only 8.4% of abdominopelvic CT reports specifically mentioned lower lung abnormalities, indicating limited clinical utility. These findings underscore the importance of optimizing CT protocols to minimize the total length of the body covered in abdominopelvic scans, thereby reducing unnecessary radiation exposure during concurrent chest and abdominopelvic CT scans.","PeriodicalId":50068,"journal":{"name":"Journal of Radiological Protection","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015122","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 personal dose equivalent at a depth of 3 mm,Hp(3), is the measurement method for monitoring the dose to the lens of the eye. Usual dosemeter type-test irradiations at non-normal angles of radiation incidence (α≠ 0°) primarily use lateral radiation exposure scenarios, where radiation approaches from the left or right, necessitating rotation of the dosemeter-phantom setup around a vertical axis. However, this method does not adequately account for bottom-to-top radiation exposures which are common in real-world situations (such as radiation scattered by a patient reaching medical staff). This study examines oblique radiation exposure conditions using a typical eye lens thermoluminescent dosemeter (TLD), Eye-D, placed on a cylindrical phantom to assess dose response at different angles and exposure energies. The study employs both low-energy (N-30 radiation quality with a mean photon energy of 25 keV) and medium-energy (N-100 radiation quality with a mean photon energy of 83 keV) x-rays at irradiation angles of-60°, 0°, and +60°, measured along the vertical and horizontal rotation axes of the dosemeter-phantom setup. The results show no significant difference between horizontal and vertical (polar and radial) rotation orientations of the dosemeter-phantom setup: recorded relative doses stayed well within ± 1 %, i.e. by far within the attributed combined uncertainty of ± 2 %.","PeriodicalId":50068,"journal":{"name":"Journal of Radiological Protection","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015119","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 more resources that are spent on radiological protection, the lesser resources are available for other needs. The ALARA principle states that exposure of ionising radiation should be kept as low as reasonably achievable, taking into account economic and societal factors. In practice, one of several approaches to determine what is considered as reasonably achievable is cost-benefit analysis. A demanding part of cost-benefit analysis is to decide on anαvalue, which stipulates the value of radiological protection. There are different conversion methods on how to convert societal costs into anαvalue. However, with the assistance of recent developments within both health economics and radiological protection room for improvements was found. Therefore, the aims of the present study were to develop a new conversion method (on how to convert societal costs into anαvalue) and to provide recommendations ofαvalues for each member country of The Organisation for Economic Co-operation and Development (OECD). With the help of systematic reviews of societal costs (the value of a statistical life, productivity losses and healthcare costs) and discount rates, as well as Monte Carlo simulations of the number of years between exposure and cancer diagnosis, a new conversion method and recommendations ofαvalues could be presented. The new conversion method was expressed as a discounted nominal risk of exposure with a median (interquartile range) of 175 (136-222) per 10 000 persons per Sv for the public and 169 (134-207) per 10 000 persons per Sv for workers. For OECD in general, recommendations ofαvalues were determined to be $56-170 per man.mSv for the public and $61-162 per man.mSv for workers (2023-USD).","PeriodicalId":50068,"journal":{"name":"Journal of Radiological Protection","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142840097","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}

Fifty scans were selected, with one procedure excluded due to a high administered activity. The mean administered activity per scan was 207.2 ± 41.8 MBq, with preparation and administration times averaging 1.44 ± 1.30 min and 0.46 ± 0.31 min, respectively. The technologist's mean total finger dose received during preparation and administration was 253.5 ± 153.3 µSv per procedure. A significant positive correlation was found between the administered activity and occupational dose, with patient's body mass index, preparation time, and administration time also contributing to dose variation. Based on 703 PET-CT procedures conducted in 2022, the estimated occupational finger dose for a technologist was 178.2 mSv annually. This value is well below the International Commission on Radiological Protection's maximum permissible dose of 500 mSv.
