However, it often encounters challenges such as inconsistent engagement, media-driven narratives and cultural barriers. This study synthesises insights across nuclear-related facilities, environmental issues such as radon, public concern regarding medical exposure, and emergency preparedness, identifying persistent barriers including distrust, limited health literacy, psychological biases, and inequitable access to trusted information. By integrating evidence-based strategies from related fields, this study aims to shift radiation risk communication from one-way, technical messaging to more participatory, culturally grounded, and socially inclusive approaches. Our main result reveals that two-way dialogue and culturally tailored messaging consistently reduce scepticism and inaction compared to conventional fact-based communication, which often fails to engage diverse communities or counter bias. Case studies, such as post-Fukushima anxieties and radon mitigation efforts, demonstrate that tailored participatory communication strategies significantly enhance community engagement and foster resilience by addressing fear and distrust. These findings have implications for trust-dependent fields such as public health, where effective communication is central to preparedness and behavioural responses. From a broader perspective, the framework of this study provides a roadmap for integrating psychological, cultural, and social dimensions into risk communication, thereby bridging the gap between scientific expertise and societal needs.</p>","PeriodicalId":50068,"journal":{"name":"Journal of Radiological Protection","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147516192","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}

This sample included the two major EAS technologies currently on the market: acoustomagnetic (AM) and radio frequency (RF) systems. In addition to these measurements, numerical computations of the current densities and electric field strengths induced in body tissues were carried out for one representative AM-EAS device and several body models (adult male, adult female, child female, and a hand model) and reasonably foreseeable worst-case exposure scenarios using a real-valued magneto quasi-static solver, based on the scalar potential finite element method. The obtained measurement and computational results were compared to the different sets of exposure limits defined by the International Commission for Non-Ionizing Radiation Protection (ICNIRP) in 1998 and 2010. Our results demonstrated that current RF-EAS technology, which typically operates in the 8.2 MHz frequency range, does not conflict with the exposure limits, even under adverse exposure conditions. However, AM-EAS systems, which typically operate at 58 kHz, may lead to induced current densities in the central nervous system and induced electric field strengths in the peripheral nervous systems of adults and children that exceed the basic restrictions for the general public (up to a factor of 22.5 for the adult female bending in front of the antenna) and even for occupational exposure (up to a factor of 4.5 for the same scenario) according to the ICNIRP 1998 and 2010 guidelines under reasonably foreseeable exposure conditions, which are not covered by the assessment procedures defined in the present version of the applicable standard IEC EN 62369-1.

Then, regarding the six radiosensitive organs (spinal cord, lung, oesophagus, stomach, liver, and bladder) that were included in the study, various radiation dose metrics were calculated based on size-specific dose estimate (SSDE) derived from equivalent water diameters (<i>Dw</i>), i.e. SSDE_centrebased on<i>D</i>_win the centre of the scan range, the SSDE_meanbased on the mean SSDEs of all slices, and the organ-specific SSDE_organfor various organs, as prescribed in American Association of Physicists in Medicine Report 220. Subsequently, correlation analyses were applied to evaluate the relationship between the organ doses and each radiation dose metric and to derive conversion factors for rapid estimation of organ doses. The ranked linear correlations of the four dose metrics with each organ dose were as follows, in descending order: SSDE_organ, SSDE_mean, CTDI_vol, and SSDE_centre. The strongest and weakest correlations were found between organ dose to liver and SSDE_Liver(<i>R</i>²= 0.88),and between organ dose to the bladder and SSDE_Bladder(<i>R</i>²= 0.62) respectively, while the<i>R</i>²of the rest of the organ doses to SSDE_organwas around 0.8.

The services depend on use of the latest techniques to perform the procedures requested reliably with the minimum amount of radiation. Developing and improving such systems requires attention to prevention of any errors in the process and potential refinements in optimising radiological protection. Prevention of incidents requires any unnecessary exposure that does occur to be investigated, events analysed to identify points of potential failure and action taken to address any deficiencies. Optimisation of radiological protection and reduction of imaging dose require understanding and awareness of the techniques and how they might be adapted for individual patients. Both require staff educated and trained in imaging techniques who build on their experience and develop the services with time. Systems for prevention of incidents and optimisation of radiological protection are not just based on assessment, protocol design and analysis when imaging equipment is installed but involve continual review so that improvement becomes part of an established culture within the organisation. Issues requiring particular attention have been highlighted by the international atomic energy agency and the international commission on radiological protection has further expanded the discussion on some of these issues in recent publications. These deal with ethics in radiological protection for patients in treatment and diagnosis and optimisation of radiological protection in imaging.

This study aimed to develop and evaluate educational materials incorporating an augmented reality (AR) application to visualise scattered-radiation distributions during radiological procedures. The educational program comprised a 20-item true/false quiz, a questionnaire based on the Attention, Relevance, Confidence, and Satisfaction (ARCS) motivational model, and open-ended questions assessing perceived strengths and weaknesses. Pre- and post-training quiz scores demonstrated an improvement of approximately 10% in the overall correct-response rate, indicating measurable gains in factual knowledge related to scattered radiation and radiation protection. ARCS scores reflected high levels of learner motivation, with mean ratings of 3.98 for Attention, 3.99 for Relevance, 4.06 for Confidence, and 4.08 for Satisfaction on a five-point scale. Free-text responses suggested that visualising scattered radiation with AR facilitated a more concrete understanding of its spatial distribution and the effectiveness of protective measures. However, both ARCS feedback and open-ended comments indicated that the training content was dense and that the exercise workload was perceived as burdensome. Participants also reported usability challenges related to the application interface.

Japan's experience is unique: while evacuation orders have been lifted across multiple municipalities, some zones remain unsuitable for habitation, necessitating new policy approaches. To address this gap, Katsurao Village employed the framework to authorise land use in a 19.9 hectare district designated for wind power generation. A multi-stakeholder committee-comprising residents, experts, government authorities, and industry representatives-was established to evaluate dose-reduction measures, access protocols, environmental maintenance, and operational safeguards. The committee identified several unresolved issues, including the absence of standardised monitoring procedures, challenges in managing worker exposure, the need for clear demarcation and communication to prevent unauthorised entry, and mechanisms for transparent reporting in the event of abnormal findings.

Its primary mission was weapons component fabrication, whereby workers were potentially exposed to radioactive and non-radioactive hazards. RF worker mortality was compared to the general population, and dose-response relationships between mortality and radiation organ doses were examined. RF workers first employed between 1951 and 1979 for ⩾30 d were identified (<i>n</i>= 9397). Vital status was determined using national and state death records up to 2017. Organ doses from external photons and neutrons irritation and internalised plutonium (Pu), americium (Am), and uranium (U) were modelled as cumulative lagged total doses per year. Beryllium exposure was evaluated as an effect modifier using data from the DOE Nationwide Beryllium Medical Program. Statistical analyses included standardised mortality ratios (SMRs), Cox proportional hazard models, and excess relative risk (ERR) models. Approximately 53.2% of workers were deceased by the end of the study. Nearly 90% were monitored for radiation exposure, with a mean weighted absorbed dose of 59.0 mGy for the lungs. Nearly 45% of workers had intakes of alpha-particle emitting radionuclides, and 46.7% were monitored for neutrons. Leading causes of death included ischemic heart disease (<i>n</i>= 999) and lung cancer (<i>n</i>= 361). The highest SMRs were observed for berylliosis (SMR: 176.9; 95% CI: 76.2, 348.7;<i>n</i>< 10) and asbestosis (SMR: 4.65; 95% CI: 2.23, 8.55;<i>n</i>= 10).

Approximately 45% of workers were monitored for beryllium, with a weak non-significant indication of effect modification for lung cancer risk. The RF cohort showed no evidence of a statistically significant increase in mortality from occupational radiation exposure.
