Researchers from the Graduate School, Universitas Padjadjaran, Rezky Anggakusuma and Gemilang Lara Utama, have unveiled a practical solution to decontaminate surfaces affected by radioactive cobalt-60 (Co-60). The team formulated a novel gel combining polyvinyl alcohol (PVA), glycerol, and EDTA, which upon application effectively removed between 53% and 98% of radioactive contamination—achieving the highest success on glass surfaces. Furthermore, this study determined that increasing the EDTA concentration enhanced the gel’s efficacy across different materials, including ceramics and metal plates.

This innovation supports multiple Sustainable Development Goals (SDGs):

SDG 3 (Good Health and Well-Being): By providing a safer, more efficient method to remove hazardous radioactive residues, the gel helps protect workers and environments during nuclear decommissioning.

SDG 12 (Responsible Consumption and Production): The study introduces an environmentally considerate decontamination technique, reducing reliance on aggressive chemical cleaners.

SDG 9 (Industry, Innovation, and Infrastructure): This low-cost, scalable solution strengthens technical capacity for radiation safety and facility decommissioning practices.
