The Department of Health and Human Services, specifically the Food and Drug Administration (FDA), is seeking proposals for the calibration and maintenance of a Whole Body Counting (WBC) system at its facility in Winchester, Massachusetts. The procurement involves repairing a faulty cooling unit for a Broad Energy Germanium detector and subsequently calibrating the WBC and Thyroid systems using specific phantoms, ensuring compliance with performance standards mandated by the Office of Regulatory Affairs (ORA). This WBC system is critical for monitoring radiation exposure, and the successful contractor will be responsible for delivering repair and calibration services within a one-year period following contract award. Interested vendors must submit their proposals electronically by September 10, 2024, to Raphael Hall at raphael.hall@fda.hhs.gov, with evaluations based on the lowest price technically acceptable criteria.
