This study aimed to conduct a comprehensive evaluation of BSF values for diagnostic X-ray beams through Monte Carlo simulations. The interactions of BSFs with widely used tissue substitutes, including water, ICRU tissue, polyester, polymethyl methacrylate (PMMA), and nylon, were examined across a range of conditions, including half-value layer (HVL), field size, and energy spectra. The results demonstrate that BSF values consistently increase with larger field sizes and higher beam energies/HVLs, highlighting the significant impact of these parameters on scatter contributions. Comparative analysis of the materials revealed that water most closely approximates the BSF behaviour of ICRU tissue, with deviations of -2.08-8% across the studied energy range and field sizes. Polyester and PMMA also showed promising agreement, converging to within ± 5% of ICRU tissue at higher energies and larger field sizes. In contrast, nylon exhibited more substantial deviations, particularly in smaller field sizes and lower energies. These findings provide essential insights to improve the accuracy of dosimetric models and enhance radiation safety in diagnostic radiology applications.","PeriodicalId":21002,"journal":{"name":"Radiation and Environmental Biophysics","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143788788","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}

Exposure to low dose/dose rates of radiation can arise from multiple scenarios or events, including natural radiation exposure, the use of radiation in medicine, industry and energy production, terrorist actions and following a nuclear incident or war. Technological developments involving radiation are progressing rapidly and have the potential to benefit mankind and societal issues. The benefit of high dose exposure during radiotherapy is a well-funded area. However, the health consequences of exposure to low doses is not well understood and the area of radiation protection research (RPR) is poorly funded. High quality RPR is essential to allow updating of radiation safety regulations for optimal protection from natural, medical and occupational exposure and for assessment of radiation incidents. Continuous evaluation of risks is essential as technological developments result in new types of radiation exposure. We will overview the technologies and situations which can potentially lead to low dose exposure, evaluate what has been gained from RPR and the questions that still need addressing, discuss the current state of RPR in Europe and highlight the consequences of a failure to adequately fund this area. We conclude that increased funding for RPR is essential to maintain high competence and to allow adequate protection of the public to inevitable low dose radiation exposure.","PeriodicalId":21002,"journal":{"name":"Radiation and Environmental Biophysics","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736202","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}

Any radiation-induced biological effects can be the consequence of exposure both after hatching and during the embryonic period. Therefore, it is necessary to quantify radiation doses to the embryo when interpreting observed radiobiological effects in birds. This is especially true for areas contaminated with Ca-like 90Sr. The levels of radionuclide accumulation in the eggshell can be extremely high, which leads to chronic embryo exposure. Consequently, the objective of the present study was to develop a method to calculate the dose to a herring gull embryo exposed to 90Sr distributed in egg compartments (shell, embryo body, albumen and yolk). To achieve this, the time-dependent Sr distribution in the egg compartments was modeled. Additionally, dosimetric modeling was carried out to obtain dose factors that convert the radionuclide activity in different compartments of an egg to embryo dose at various stages of embryogenesis. It has been shown that the accumulated dose to the herring gull embryo can be calculated based on 90Sr total activity in the egg using a dose conversion factor of 0.44 μGy Bq-1. Since the eggshell contains more than 90% of total 90Sr activity, the conversion from eggshell activity to embryo dose would be practically the same as that from the total egg activity - 0.46 μGy Bq-1. The main dose fraction (~ 99%) accumulates at the last stage of embryogenesis (from 13 to 26 days). The proposed method allows for an estimation of individual radiation doses to embryos based on eggshell radiometry. This creates a new opportunity to study how dangerous any radiation exposure of birds could be during the embryonic period.","PeriodicalId":21002,"journal":{"name":"Radiation and Environmental Biophysics","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143731472","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}

Based on symptoms, digital rectal examination (DRE), prostate-specific antigen (PSA) level in the blood, or histopathology from transrectal ultrasound-guided biopsy and 4Kscore Test, 120 patients have confirmed PCa. Sixty of them were scanned on a PET/CT machine using 18F-FDG, and the other 60 patients were scanned using 68Ga-PSMA of radiopharmacy. Each tumour was delineated using PET. Edge texture parameters were used to define each tumour, and 73 features in all were taken from eight distinct texture matrices and computed using the open-source program Chang-Gung Image Texture Analysis (CGITA). Using Spearman correlation, feature correlation with conventional quantitative metrics (Maximum Standardized Uptake Value (SUVmax), Total Lesion Glycolysis (TLG), Metabolic Tumor Volume (MTV)) was investigated, and it was found that the High-Intensity Low-Energy Radiation (HILRE) correlation was strong. PCa was best discriminated by HILRE (64-bin) in receiver operating characteristic curves. It is concluded that 68Ga-PSMA-based PET imaging is better than 18F-FDG-based PET and is strongly associated with PCa tumour allocation. According to extracted features, HILRE is the most significant measure and it is, thus, considered here an independent predictor of PCa prognosis.

In-vivo dosimetry (IVD) is used in external beam radiotherapy to evaluate the delivered versus planned dose as a patient-specific quality assurance verification procedure. This study aimed at assessing the performance of diodes (EDP-103G and EDP-203G) and metal oxide semiconductor field-effect transistors (MOSFETs) and corresponding correction factors followed by IVD evaluation in different treatment configurations. Linearity, stability, gantry angle, field size, and source-to-subject distance (SSD) were assessed across various photon energies, with correction factors determined. To minimize patient movement uncertainty, the study utilized the Alderson Rando phantom to replicate clinical setups, comparing diode and MOSFET dose readings to treatment planning system (TPS) doses. Diodes and MOSFETs were evaluated across different photon energy levels for brain, chest, and pelvis planning sites. Diodes and MOSFETs demonstrated good stability and linearity at the different utilized photon beams. Data analysis showed that MOSFETs had a slightly higher sensitivity compared to diodes in gantry angle, field size and SSD corrections. Regarding the validation process after applying the correction factors, dose variations between diode readings and TPS doses were found to be 1.89%, 1.58%, and 6.72% for brain, breast, and pelvis, respectively. In contrast, MOSFET readings were 2.40% for brain, 2.03% for chest, and 2.03% for pelvis. It is concluded that, while diode and MOSFET dosimeters both allowed for accurate patient dose measurements, for different anatomical sites, MOSFETs demonstrated better performance for the pelvis compared to diodes.","PeriodicalId":21002,"journal":{"name":"Radiation and Environmental Biophysics","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143543144","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}
