Request for Information (RFI) issued by the National Nuclear Security Administration (NNSA), Office of Radiological Security (ORS). The purpose of this RFI is to conduct market research to identify manufacturers and vendors capable of supplying self-shielded X-ray irradiators suitable for various research applications. The insights gained from this RFI will assist the ORS in understanding current market capabilities, promoting X-ray technology alternatives to high-activity radioactive sources, and impartially including relevant vendors in future ORS engagements. See attached RFI for further details.
