Ocular Oncology and Radiology Department, S. Fyodorov Eye Microsurgery Federal State Institution, Moscow, Russia.
Purpose: To retrospectively evaluate the efficacy of plaque brachytherapy for the treatment of retinoblastoma.
Methods: We retrospectively reviewed the clinical records of 163 patients (186 eyes, 333 tumors) treated with brachytherapy (Ru or Sr plaques) for intraocular retinoblastoma between November 2007 and August 2023.
Results: Complete tumor control was achieved in 273 tumors (82%).
STUDY OF DOSE FORMATION FOR THE POPULATION IN RADIOACTIVELY CONTAMINATED AREAS OF ZHYTOMYR REGION BASED ON COMPREHENSIVE RADIATION-HYGIENIC MONITORING.

WHO Country Office in Ukraine, 9B Mykhaila Hrushevskoho Str., Kyiv, 01021, Ukraine.
Objective: the research is to determine the main radiation-hygienic factors influencing the formation of radiation doses among the population of radioactively contaminated territories (RCT) in Zhytomyr region in 2024 and to analyze the dynamics of internal radiation doses based on original experimental studies conducted in reference settlements from 2012 to 2024.
Materials And Methods: In 2024, a comprehensive radiation-hygienic monitoring program was conducted in 11 settlements of Narodychi Territorial Community (TC): the Narodychi and the villages of Selets, Bazar, Rudnya Bazarska, Khrystynivka (Zone 2), Motiyki, Zalissya, Davydky, Radcha, Nova Radcha, and Grezlya (Zone 3). The comprehensive radiation-hygienic monitoring included the following activities: mobile WBC monitoring: 817 measurements (562 adults and 255 children); collection and analysis of food samples: 39 milk samples, 61 potato samples, and 57 samples of wild foods, analyzed for radionuclide content, including 137Cs and 90Sr; assessment of external radiation exposure in these settlements; surveys: 194 individuals were surveyed regarding the consumption volumes of locally produced foods from their own households and purchased foods from commercial networks.
Optimization of pretreatment protocol for strontium-90 analysis in marine fish bone samples.

Institute of Radiation Emergency Medicine, Hirosaki University, 66-1 Hon-cho, Hirosaki 036-8564 Aomori, Japan.
For systematic monitoring of radioactive nuclides in marine products, this study aimed at streamlining and simplifying the analysis method for the prominent radioisotope, strontium-90 (90Sr). The DGA chelate solid-phase extraction technique was employed for enhanced efficiency. The study focused on optimizing the necessary pretreatment procedures while minimizing the steps involving HNO3 leaching.

Monitoring of the content of technogenic radionuclides (Cs-137 and Sr-90) in foods is one of the key areas in ensuring radiation safety of the population, taking into account the current radiation situation. The greatest risk to health is food produced or imported from the territories that have been subjected to man-made radiation accidents. of the research was to assess the radiation risk caused by oral intake of radionuclides based on the study of the actual nutrition of the adult population and contamination of food with Cs-137 and Sr-90 radionuclides.

In this work, we explored the role and mechanism of sea buckthorn oil in reducing radiation-induced skin damage. The radiation-induced rat skin injury model was established using strontium-90. Rats were treated with sea buckthorn oil twice a day postirradiation, and skin damage was observed at different times and evaluated using an injury score.
