The estimated decommissioning dates for the first NPPs are projected around 2046. The National Atomic Energy Commission (CNEA) is mandated to determine the decommissioning procedures for nuclear facilities in Argentina and has the responsibility of dismantling and decommissioning Argentine NPPs. Unfortunately, despite a prior Nuclear Facilities Decommissioning Sub-Program, this initiative was discontinued, leading to retirement or reassignment of many involved personnel. Now, the National Radioactive Waste Management Program (PNGRR) within CNEA is developing a Comprehensive Decommissioning Plan for Argentina’s nuclear facilities. This plan is crucial to address current and future generations’ interests and legal responsibilities of CNEA. The plan starts with decontamination and dismantling tasks for selected nuclear facilities as case studies. The Comprehensive Decommissioning Plan progresses through three stages with incremental goals: surveying the current situation, defining strategies, and implementing them. Each phase involves coordinating research and development efforts, planning strategies based on knowledge management, and transferring information between past and present professional and technical personnel. Additionally, specific techniques and technologies will be applied in precise case studies, competencies will be mapped to design tailored training and human resources development programs, and international cooperation agreements will be fostered to exchange knowledge on the subject.","PeriodicalId":747,"journal":{"name":"Radiochemistry","volume":"67 4","pages":"424 - 431"},"PeriodicalIF":1.0,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We summarize common nanoparticle physicochemical characterizations, typical in vitro protocols (cell lines, dosimetry, and endpoints), and major biological readouts (viability, clonogenic survival, γH2AX foci, ROS). Across studies, highZ NPs (Au, Ag) and hybrid formulations frequently increase radiationinduced DNA damage and oxidative stress and reduce clonogenic survival, although the efficacy varies with the particle size, surface chemistry, concentration, cellular uptake, beam energy, and cell type. We synthesize mechanistic evidence supporting three principal mechanisms of nanoparticle radiosensitization—physical dose amplification, chemical ROS amplification, and biological modulation of DNA repair and cell death pathways—and discuss limitations that have delayed clinical translation (toxicity, dosimetry, biodistribution, reproducibility). Finally, we provide a prioritized set of recommendations to accelerate translation to in vivo validation and clinical testing.","PeriodicalId":747,"journal":{"name":"Radiochemistry","volume":"67 4","pages":"432 - 440"},"PeriodicalIF":1.0,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sorption equilibrium in the systems under consideration was proved by the coincidence of the experimental and literature values of the La(III) and Ce(III) ion hydrolysis constants and the data of sorption kinetics. The presence of surface terminal and bridging OH groups in TiO2, according to 1H NMR data, allowed using a model of surface complexation with the participation of functional groups {≡TiOH0} and {≡TiO–} to describe the sorption. Varietal Henry’s constants of sorption of hydroxy and carbonate complexes of La(III) and Ce(III) within the framework of the two-Ka model were found.

To ensure the safety of radioactive waste disposal in the host rock environment, it is necessary to thoroughly study the properties of the colloids formed and determine their influence on the retention of radionuclides by crystalline rocks. This work investigates the influence of colloidal particles of bentonite from the Tagansky deposit on the sorption of 137Cs, 90Sr, 241Am, 239Pu, and 237Np on samples of the host rock from the Yeniseisky site. Kinetic dependences were obtained, and the quantitative parameters of sorption of the above-listed radionuclides in a model groundwater solution on the colloidal fraction of bentonite from the Tagansky deposit and on intact rock samples were determined. A comparison of the sorption capacity of clay colloids and host rocks showed that the host rock makes a major contribution to the sorption of cesium and strontium, whereas plutonium and neptunium are predominantly retained by the colloidal fraction. The formation of even a small amount of colloidal material from engineered safety barrier materials influences the behavior of radionuclides under DGR conditions.","PeriodicalId":747,"journal":{"name":"Radiochemistry","volume":"67 4","pages":"534 - 543"},"PeriodicalIF":1.0,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
