The Department of Energy, through the Battelle Energy Alliance at the Idaho National Laboratory (INL), is seeking innovative solutions for the development of novel training surrogates for emergency response training. The objective is to create short-lived radioisotopes that can effectively simulate the behavior and emissions of actual radioactive materials, thereby providing realistic training scenarios for emergency response personnel without the associated radiotoxicity risks. This initiative is crucial for enhancing the preparedness of military and emergency response teams, as it addresses the challenges of training with hazardous materials while ensuring safety and environmental considerations. Interested parties can contact Andrew Rankin at andrew.rankin@inl.gov for further information regarding licensing opportunities and collaboration, as this project is not a solicitation for external services or funding.
