Accurate modeling of particle resuspension dynamics is essential for developing effective mitigation strategies and ensuring public and responder safety. However, default resuspension factors in models may underestimate risks, particularly during emergency operations involving pedestrian and vehicle activity on freshly contaminated surfaces. To address these gaps, we conducted pilot-scale field experiments using Arizona Test Dust (ATD) as a surrogate for threat agents. Human activities included casual walking, vigorous walking (marching), and vacuuming on concrete surfaces, while vehicle tests involved driving a sport utility vehicle (SUV) over asphalt in both drive-through (tires passing over dust) and drive-over (undercarriage passing over dust) configurations. Resuspension factors (Sf) were calculated for particle size ranges from 0.5-10 µm. Casual walking produced low resuspension factors, from <10-5 m-1 for 0.5-1.0 μm particles to <3 × 10-3 m-1 for 5-10 μm particles. In contrast, marching, which served as a surrogate for vigorous pedestrian or personnel movement, substantially increased resuspension, with Sf values ranging from 2 × 10-5 m-1 at 0.1-1 μm to 2 × 10-3 m-1 for 5-10 μm particles. Vacuuming caused measurable resuspension for smaller particles (Sf = 1.4 × 10-3 m-1), while larger particles remained undetectable. Vehicle tests showed higher resuspension factors for larger particles, with Sf values ranging from 3 × 10-4 m-1 to 2 × 10-2 m-1 during the first pass. Subsequent passes eventually reduced resuspension factors by an order of magnitude. These findings reveal significantly higher resuspension during emergency operations than many models assume. Our results apply to scenarios involving radioactive fallout, chemical, and biological agents, offering critical data to improve contamination control, emergency response planning, and risk assessment models.</p>","PeriodicalId":12976,"journal":{"name":"Health physics","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148591341","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}

This study explores the feasibility of using existing radiation portal monitors to detect rhinoceros horns implanted with radioactive sources during international sea transportation. By leveraging the Gamma Detector Response and Analysis Software, a series of simulated pass-bys were conducted under controlled variables, including fill capacities, material densities, and 60Co source strengths. The models incorporated a 6.10-m (20-ft) shipping container with a keratin horn configuration, simulating realistic concealment scenarios. Background environments were modeled after Denver, CO, to reflect elevated natural radiation conditions. Detection performance was assessed using theoretical probability of detection, incorporating International Atomic Energy Agency Nuclear Security Series No. 1 standards for operational consistency. Results show that increased cargo capacity and denser shielding materials, such as aluminum and stainless steel, reduce probability of detection, though such solid-block shielding is unlikely in real-world cargo. Shadow shielding from empty or lightly filled containers enhanced detection capability by reducing background noise. Furthermore, modeling scenarios with multiple horns improved probability of detection, aligning with seizure patterns observed in sea transport trafficking cases. While the study does not determine the minimum detectable activity due to law enforcement sensitivities, it demonstrates the plausibility of radiation portal monitor systems identifying radiologically tagged horns under realistic shipping conditions. The findings support the concept of radiation tagging as a cost-effective, scalable strategy to deter trafficking, increase seizure rates, and reinforce international conservation efforts without disrupting trade flow or requiring infrastructure overhauls.</p>","PeriodicalId":12976,"journal":{"name":"Health physics","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148470108","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}

Field experiments conducted at different flight altitudes were used to evaluate background radiation components, attenuation effects, and data consistency. Altitude-profile maritime flights and linear regression analysis enabled separation of helicopter-related and altitude-dependent background contributions, while Monte Carlo simulations, assuming an infinite half-space ground distribution, were used to derive altitude-dependent attenuation correction factors for converting aerial measurements to dose rates at 1 m above ground level. The reliability of the corrected aerial survey results was verified through statistical comparison with carborne survey data, demonstrating overall consistency despite differences in measurement geometry and spatial averaging. In addition, the BG-index and Cs-index methods were shown to provide a robust means of discriminating between background radiation and radioactive cesium under low count rate and high-altitude conditions.

Although case reports and small series have described cutaneous malignancies in radiation-exposed personnel, epidemiological characterization remains limited due to scarce population-based data and inconsistent dermatological surveillance. This scoping review synthesizes the available evidence on occupational skin lesions in interventional staff, focusing on anatomical distribution, tumor characteristics, and protection gaps. The purpose of this paper is to map and summarize the scientific evidence on malignant and non-malignant skin lesions reported among interventional catheterization personnel exposed to ionizing radiation. A scoping review was conducted following PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines across major scientific databases. Eligible studies reported occupational skin cancer, precancerous lesions, chronic dermatological changes, or asymmetric radiation exposure among interventional personnel. Two reviewers independently screened studies and extracted data using a standardized template. Six studies met the eligibility criteria, comprising five descriptive publications (case reports and a small case series) and one large prospective cohort of radiologic technologists involved in fluoroscopically guided procedures. The descriptive evidence reported 120 tumors with documented laterality, 79.2% of which occurred on the left side of the body, predominantly affecting the face, neck, and upper extremities, consistent with scatter-radiation geometry. Basal cell carcinoma was the most frequent tumor type (76.7%), followed by squamous cell carcinoma (23.3%). The cohort study reported elevated hazard ratios for melanoma, while estimates for basal and squamous cell carcinomas remained near unity. Overall, 96% of lesions occurred in anatomical regions not covered by conventional protective shielding. The evidence reveals a consistent pattern of asymmetric lesion distribution in unshielded anatomical regions and highlights critical gaps in dermatological surveillance, exposure assessment, and skin dosimetry among interventional personnel.</p>","PeriodicalId":12976,"journal":{"name":"Health physics","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148420710","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}

It has been used extensively by US regulatory agencies for many decades to establish radiation exposure limits and to estimate future health (primarily cancer) effects for both projected (e.g., for a proposed nuclear facility or activity) and previous radiation exposures. The model assumes a linear relationship between dose and health effects, even for very low doses within the range of natural background radiation, where biological effects may be difficult or impossible to observe or may not exist. The LNT model implies that all exposure to ionizing radiation is harmful, regardless of how low the dose, since it assumes there is \"no safe threshold\" for exposure to radiation. That is, based on the implications of the LNT model, any exposure could result in increased cancer and possibly undesirable genetic effects. A major objective of this paper is to provide data and approaches that we as health physicists can use to communicate these highly controversial and misunderstood concepts more effectively to the public. Our target audience is often not health physicists or physical scientists but a reasonably educated audience where the data, concepts, and approaches suggested herein can be useful. As health physicists, it is our nature to try and be as \"rigorous\" and \"precise\" as we can with our terminology and mathematical expressions. Trying to be effective communicators of scientific concepts to nonscientists in this manner can often be self-defeating rather than just communicating in a simple and \"familiar\" manner. For example, although it is suggested that both the international and US units of effective radiation dose [millisieverts (mSv) and millirem (mrem) respectively] are explained, it unnecessary to include in discussions with \"the public\" equivalences with other larger or smaller units such as Sieverts vs. Rem or microsieverts vs. microrem, which confuse and do not add to understanding of the basic concepts we are attempting to communicate. A similar approach should be used with units of radioactivity present, e.g., picocuries (pCi) vs. the international and/or larger equiveillances such as Becquerels (Bq) or Curies (Ci). The pCi is the only unit the US EPA uses for remedial action soil concentrations in their applications of the LNT described here and is the unit used by US commercial laboratories to report results, so it is already \"familiar\" to many people. Additionally, nonscientists/engineers are not necessarily familiar with scientific notation using powers of ten (10x, e.g.) and in particular, negative exponents such as 3 × 10-4, but most people can understand that the decimal equivalent, 0.0003, is a very small number. Accordingly, some flexibility in communication is suggested relative to the health physics profession's usual rigorous (and appropriate) application of our professional standards of practic","PeriodicalId":12976,"journal":{"name":"Health physics","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2026-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148420790","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}

These measurements remained within established international safety guidelines. Health risk assessment involved calculating radiation hazard parameters, including annual effective doses, lifetime cancer probability estimates, and organ-specific dose distributions for both interior and exterior exposure conditions.
