2.0 Site Status Summary
Texas Instruments (TI) conducted uranium operations from 1952 to1981, and manufactured one product with Ra-226 in the 1950's. Prior to Massachusetts becoming an Agreement State in 1997, TI satisfactorily remediated the site of by-product material (i.e., Uranium), thus, the license was terminated by the NRC in 1997. At that time, one building - Building 1 - was found to contain small amounts of Ra-226 in the floor, which would require remediation if the building was sold to another entity, or prior to the building being demolished. The Ra-226 found in the floor of Building 1 was from the manufacturing of toggle switches for use on U.S. Navy submarines. TI placed the Ra-226 bead onto each toggle switch so that the switch would glow in the dark. It is unclear who made Ra-226 beads and shipped them to TI. In late 2006, TI sold it's Attleboro site to Bain Capital, who then formed a new company - Sensata Technologies - but TI is still responsible for the Ra-226 cleanup. As of May 2008, Texas Instruments is assessing the extent of contamination in preparation for a decommission submission plan to be approved by the Massachusetts Radiation Control Program. Cleanup to dose based standard of < 10 mrem/yr TEDE.
