This single-center, open-label, randomized controlled trial conducted at Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, evaluated scattered radiation exposure to the primary operator during procedures via radial, femoral, and pectoral vascular access sites and the effectiveness of radiation protection drapes in reducing this exposure. A total of 216 patients (72 in each vascular access group) were randomized using coin flipping to receive either standard radiation protection or additional shielding with a radiation protection drape. The primary operator's scattered radiation dose was assessed in comparison to the radiation emitted during the procedure, with normalization to procedural radiation parameters including air kerma (AK), dose area product (DAP), and cine-adjusted screen time (CAST). Pectoral access was associated with the highest operator exposure (96.75 µSv) compared to femoral (45.72 µSv) and radial (49.06 µSv) access, despite lower AK values. Radiation protection drapes significantly reduced operator exposure across all access sites, with radial access showing reductions of 51% (DAP), 48% (AK), and 53% (CAST); femoral access showing reductions of 82% (DAP), 74% (AK), and 63% (CAST); and pectoral access showing reductions of 62% (DAP), 49% (AK), and 52% (CAST), all statistically significant (P < 0.05). No adverse events were reported. The findings provide strong support for the routine use of radiation protection drapes to minimize primary operator radiation exposure during catheterization procedures, especially when using the pectoral access site.","PeriodicalId":12976,"journal":{"name":"Health physics","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146104770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the concept is simple and easy to understand, its application, including the basis for judgments and the process for reaching a decision, is not straightforward. It has been demonstrated in the last decades that the decision-making process in radiological protection and safety requires not only scientific and technical rationality but also consideration of stakeholder views to appropriately reflect societal and ethical values. In view of these emerging challenges, the International Commission on Radiological Protection created Task Group 124 for the purpose of revisiting and modernizing the principle of justification. The Task Group collected various views and opinions of radiation protection experts through an online workshop and an international conference. They were examined to identify areas that need further clarification and to extract ideas that were not given sufficient consideration in the past. The Task Group is working to compile a report that identifies essential elements and key perspectives in the decision-making process for justification. It aims to clarify what \"do more good than harm\" means in society today and on what basis the judgment should be made.","PeriodicalId":12976,"journal":{"name":"Health physics","volume":"130 2","pages":"162-165"},"PeriodicalIF":1.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145888965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Health physicists use complicated mathematical equations and dose calculation algorithms to create precise and detailed dose reconstructions, but this is dependent upon the release of information regarding the exposure or contamination scenario. The Radiation Emergency Assistance Center/Training Site employs and teaches certain \"rules of thumb\" dose estimation techniques for both internal and external exposures, which may help in early phase dose reconstruction and for predicting health outcomes by health care providers. This includes using the point source equation and inverse square law to estimate a person's exposure from a source at a given distance, assessing internal inhalation intakes, and estimating internal deposition based on initial uptake measurements from wound or nasal contamination. Biodosimetry techniques can be used to estimate the absorbed dose, with dicentric chromosome assay being the gold standard. Other biodosimetry techniques include evaluating symptoms of acute radiation syndrome and cutaneous radiation injury. The intent for these initial dose reconstruction techniques is not to replace the existing dosimetry techniques but to allow rapid initial patient triage, so that life-saving interventions may be employed immediately.","PeriodicalId":12976,"journal":{"name":"Health physics","volume":"130 2","pages":"175-182"},"PeriodicalIF":1.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145888884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants were sampled using a convenient systematic method.Results: Results revealed that both patients and household members had low knowledge and awareness about medial radiation. However, they demonstrated a strong positive attitude toward the use of radiation in medicine indicating trust in healthcare practices despite limited understanding. In contrast, clinicians showed high levels of knowledge and awareness highlighting their essential role safe and effective use of radiation as justification principles demand.Conclusion: Improving public knowledge and awareness about medical radiation is essential to compliment the positive attitude observed and to enhance radiation safety practices in hospitals.

The collected data for systems of interest for space exploration are discussed, and the literature gaps are indicated. The data are also compared with the nuclear fragmentation models implemented in the NASA radiation transport code HZETRN2020, namely NUCFRG3 and RAADFRG. The results show that NUCFRG3 does not take into account nuclear-structure effects, while RAADFRG does. Therefore, RAADFRG can estimate more precisely the production of certain projectile fragments, in particular helium.

For a given exposure situation, it is necessary to ask whether the doses received (or potentially received) by those exposed can be considered tolerable with regard to the radiation-induced risk (consistent with the principle of application of dose limits). In addition, it should be assessed whether all exposures are maintained or reduced as low as reasonably achievable taking into account economic, societal, and environmental factors (consistent with the principle of optimization of protection). Relying on the ethical foundations of the ICRP system (i.e., Publication 138), ICRP Task Group 114 (TG114) is engaged in a critical reflection on the history, definitions, roles, scope, and application of \"tolerability\" and \"reasonableness\" in the context of radiological protection. In developing and articulating a revised framework for tolerability and reasonableness, focusing on the achieved level of protection and the concept of well-being, consideration has been given to application of this framework in different contexts. This paper provides a brief overview of the motivation and current work of TG114 and highlights key points for the application of the proposed revised framework in three contexts: i.e., medicine, emergency and recovery after a nuclear accident, and the nuclear sector.","PeriodicalId":12976,"journal":{"name":"Health physics","volume":"130 2","pages":"166-174"},"PeriodicalIF":1.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12736415/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145888985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
