Abstract. Effective decontamination is crucial for managing radioactive waste, and it is important to find optimal practices that consider factors such as ease of use, reduction in secondary waste, and hazardous nature of the material. The study evaluates a chemical decontamination gel effectiveness in removing radioactive materials from commonly used materials at IFIN-HH. Artificially contaminated materials were tested, and the gel decontamination factor was evaluated. The gel has advantages such as easy application, high decontamination factor, and minimal contamination of radioactive materials, making it a promising method for efficient and safe management of radioactive waste.

Key words: Chemical gel, decontamination, radionuclides, radioactive waste, radiation measurement, radiological contamination, gamma-ray spectrometry.
