1. Radiological protection, optimisation and regulatory reform.
PMID:期刊:日期:2026-10-01The principle of optimisation of protection is a cornerstone of the system of radiological protection (RP). The practical implementation and interpretation of optimisation, particularly at low doses and dose rates, is a long-recognised challenge and has often been subject to robust and spirited debate. At present, we seem to have unprecedented interest and momentum for reflection on RP recommendations and standards, and with it the opportunity to collaboratively develop creative solutions to such challenges in support of a sustainable future. Potential solutions should be informed by science as well as a wide range of social and economic factors and be thoroughly and critically evaluated accordingly. In the United States (US), Executive Orders have led to relevant proposed rule changes from the US Nuclear Regulatory Commission (NRC), including one entitled 'Reforming and Modernizing the NRC's Radiation Protection Framework'. This paper argues that the proposal is rushed, imprecise and insufficient by highlighting a few illustrative examples of how the proposed rule change as written is inconsistent with international (e.g. International Commission on Radiological Protection) and national (e.g. US National Council on Radiation Protection and Measurements) recommendations and guidance. For example, the proposal claims that adherence to regulatory dose limits provides a sufficient level of protection and that beyond prescribed actions at certain thresholds, there is no need for further incorporation of the prevailing circumstances (i.e. no need to optimise protection) below these dose limits. National authorities of course have the purview to decide what is most appropriate and effective from a regulatory standpoint, but diverging from the broader consensus requires a clear, thoughtful, thorough and transparent argument that is missing from the current proposal.

2. A criticism of three arguments on recurrent imaging and risk.
PMID:期刊:日期:2026-09-29Managing radiation protection (RP) in relation to recurrent imaging continues to be debated. Recent arguments have focussed on high Cumulative Effective Dose (CED), especially where it exceeds 100mSv. 
This article argues that CED should not be the primary focus for tracking concerns on recurrent imaging. Arguments which advocate for increased RP measures after 100mSv is exceeded are criticised as being in conflict with the LNT model. Finally, a view of dose history as adding to background risk is discussed.

4. Integrated spatiotemporal assessment of ambient radiation fields in a nuclear medicine department using OSL and time-resolved Geiger-Müller monitoring.
PMID:期刊:日期:2026-09-25Occupational radiation protection in nuclear medicine is complicated by ambient radiation fields that vary both spatially and temporally. This variability arises from routine radiopharmaceutical handling and from patients who act as temporary mobile radiation sources after administration. Passive dosimetry provides cumulative information but cannot resolve short-term fluctuations arising during routine operations. This study integrated fixed-location optically stimulated luminescence (OSL) dosimetry with time-resolved Geiger-Müller monitoring to characterise spatial variations in ambient dose equivalent and temporal variations in dose-rate in a clinical nuclear medicine department. Monthly ambient dose equivalent,*(10), was measured at 34 positions grouped into 14 functional areas across controlled, supervised, and uncontrolled zones, while ambient dose rate was recorded at 1 s intervals during routine working hours (08:00-16:00 h) over four weeks. Location-based estimates of annual effective dose (AED) and excess lifetime cancer risk were derived from the OSL measurements. At the functional-area level, the syringe placement area showed the highest monthly*(10) (0.405 mSv month), followed by the patient waiting room (0.288 ± 0.214 mSv month) and injection room (0.204 ± 0.101 mSv month). The patient waiting room also recorded the highest four-week mean dose rate (1.21 ± 0.24Sv h). Functional-area AED indicators ranged from 1.18 to 5.30 mSv y, reflecting spatial variation in the annualised exposure estimates.*(10) did not differ significantly among the three zones (= 0.262), it differed significantly among locations within the controlled zone (= 0.046). Time-resolved monitoring further revealed transient dose-rate peaks that were not apparent in cumulative dosimetry. Integrated monitoring may provide a more comprehensive basis for spatial prioritization and workflow-informed optimisation of radiation protection.

6. CT image-based evaluation of phantom-derived DLP-to-effective dose conversion factors for adult abdomen-pelvis CT.
PMID:期刊:日期:2026-09-23Effective dose is used in computed tomography (CT) as a population-level quantity for radiation protection, dose monitoring, and clinical studies. It is commonly estimated by multiplying scanner-reported dose-length product (DLP) by a conversion coefficient, or k-factor, because organ doses are not available from routine examinations. Most CT k-factors were derived from computational human phantoms, but phantom-derived estimates have not been systematically compared with effective doses calculated directly from CT images across adults with diverse body habitus. We calculated k-factors using a set of adult abdominal CT images combined with Deep Learning-based automatic organ segmentation and Monte Carlo dose calculation methods and compared them with those calculated from two phantom-derived k-factor approaches: the fixed AAPM TG23 coefficient and body size-dependent k-factors calculated using National Cancer Institute dosimetry system for CT (NCICT). Abdomen-pelvis CT images from 38 adults (18 females, 20 males) spanning water-equivalent diameter (WED) values of 21-41 cm were segmented using TotalSegmentator and an in-house gonad model, converted into voxelized anatomical models, and coupled with a validated CT scanner Monte Carlo model. CT image-based k-factors were calculated as effective dose divided by DLP and evaluated as functions of WED and sex. Image-based k-factors decreased with increasing WED for both sexes, and female values were higher than male values at comparable WED. Over the overlapping WED range, NCICT-based k-factors showed good agreement with CT-based values with the same decreasing trend. The fixed TG23 coefficient introduced systematic bias at smaller and larger body sizes. However, the selected NCICT adult phantoms did not cover the lower-WED end of the CT cohort. These findings support the performance of phantom-based effective dose calculations and indicate the need to extend phantom libraries while continuing CT image-based evaluation across pediatric CT and broader imaging protocols.

7. Bridging the gap between national policy and local implementation: analysis of sheltering-in-place policy development and stakeholder concerns in Japan.
PMID:期刊:日期:2026-09-18Preparedness for nuclear and radiological emergencies increasingly requires considering complex scenarios, including compound disasters, disruptions to critical infrastructure, and challenges in public communication. In Japan, following the Fukushima Daiichi Nuclear Power Station accident, sheltering-in-place (SIP) has been designated as a key protective action for residents within the urgent protective action planning zone. However, recent events, including the 2024 Noto Peninsula Earthquake, have highlighted operational challenges and renewed concerns regarding the implementation of SIP. This study examined SIP policy development in Japan by analysing discussions of the Nuclear Regulation Authority's 'Study Team on the Operational Use of SIP' held between April 2024 and March 2025. A qualitative document analysis was conducted using publicly available meeting records, supporting materials, the final report, and comments submitted by local governments and the public during public consultations. Findings indicate the study team clarified key operational SIP elements, including initiation, geographic scope, continuation, termination, transition to evacuation or temporary relocation, temporary outings, and information provision. However, comments from local governments and the public revealed persistent concerns regarding legal and institutional consistency, compound-disaster response, public communication, information dissemination systems, continuity of social and business activities, support for healthcare and welfare facilities, maintenance of lifelines and essential supplies, and coordination among governmental and allied organisations. These findings suggest that successful SIP implementation depends not only on technical criteria, such as dose assessment and protective action thresholds, but also on effective risk communication among governments, healthcare and welfare institutions, businesses, and residents. The principal challenge is translating national policy into locally understandable and actionable practices; strengthening stakeholder engagement, public communication, and community preparedness may facilitate this translation. Future studies should evaluate whether these measures improve practical preparedness and emergency response.

8. Modelling radiation adaptive response in space radiation risk assessment using Monte Carlo simulation.
PMID:期刊:日期:2026-09-18Uncertainty surrounding the biological effects of chronic low-dose radiation remains an important challenge in radiation risk assessment, particularly for long-duration space missions. Although adaptive response has been proposed as a potential modifier of radiation-induced cancer risk, its impact on mission-level risk predictions has not been quantitatively evaluated. We developed an exploratory Monte Carlo framework that extends a conventional linear no-threshold-based cancer risk model by incorporating an adaptive response factor (RAF) parameterised by a maximum protection fraction (), a half-saturation priming dose (), and a persistence time constant (). Organ-specific equivalent doses and model parameters were sampled for representative International Space Station (ISS), lunar, and Mars mission scenarios over 100 000 iterations per organ-mission pair. Under the implemented single-priming with exponential decay formulation, adaptive response produced only modest changes in projected cancer risk. Median reductions were negligible for the 1000 d Mars mission and remained below 1% for ISS scenarios, while larger reductions occurred only in a small fraction of simulations associated with favourable adaptive-response parameters. Within the assumptions of the current model, adaptive response is unlikely to substantially alter mission-level cancer risk estimates. Nevertheless, the proposed framework provides a transparent method for evaluating alternative biological hypotheses and quantifying their potential influence on radiation risk assessment as new experimental evidence becomes available.

10. Cumulative and real-time performance of consumer-grade electronic radon monitors in a Canadian single-family home over three months.
PMID:期刊:日期:2026-09-17Consumer electronic radon monitors (ERMs) are increasingly used for residential screening, yet long-term field evaluations under real-world conditions remain limited. This study conducted a 98-day collocation of 15 models of ERMs (3 units each; 45 total) alongside a calibrated research-grade reference instrument (AlphaGuard PQ2000) and two alpha-track detectors (Radtrak; Radonova) in the lowest lived-in space of an occupied single-family home in Waterloo, Ontario, Canada, while concurrently recording environmental parameters, including PM, CO, temperature, and relative humidity. The average radon concentration reported by the reference instrument was 99 Bq m, with a range from 62-141 Bq m. The cumulative and real-time ERM performance was assessed using a variety of metrics. Performance varied substantially across and within models. Eight out of the fifteen models had two or more units that achieved a relative percent error (RPE) within ±25%, with the top performers achieving an RPE of 3%-5% after 13 weeks of deployment, while several other devices under- or overestimated, from negative 47% to positive 220%. Most models showed acceptable intra-model repeatability with a coefficient of variation lower than 15%. For real-time performance, top-performing ERMs achieved a root mean square error of 5-6 Bq m, and moderate (= 0.70-0.77), statistically significant Spearman-rank correlations on two-day non-overlapping averages. Overall, selected ERMs can approximate long-term cumulative average concentrations under real-world conditions, making them appropriate for long-term radon risk screening. However, the variability in ERM performance also highlights the need for regulatory oversight and independent testing to protect building occupants from a false sense of security or false alarms.
