The Department of Health and Human Services, specifically the National Institutes of Health (NIH), intends to award a sole source contract to Thermo Eberline for the provision of services and maintenance for existing radiation detection equipment at the NIH Clinical Center in Bethesda, Maryland. The procurement involves maintenance for three Thermo Eberline FHT 3511 PET Stack Monitors and one FHT-59 PING radiation detector, which are critical for monitoring exhaust emissions from several facilities. This acquisition is being conducted under the Federal Acquisition Regulation (FAR) Part 13, allowing for a sole source award due to the unique capabilities of Thermo Eberline as the only manufacturer of the required equipment. Interested parties may express their interest and capabilities to Kristin Nagashima at kristin.nagashima@nih.gov by April 17, 2025, at 12 PM EST.
