Superfund Site Profile
The H&K Sales site is also known as the "Belding Warehouse" site or as one of the "Michigan Radiological" sites. The site consists of a large warehouse in downtown Belding, Michigan. H&K Sales, Inc. rented space in the building in 1994 to store World War II-era aircraft parts. Some of the parts had originally been painted with small amounts of radium-226, a solid, naturally occurring radioactive isotope. The isotope gives off alpha particle and gamma ray radiation when it decays, which is potentially harmful to human health. Moreover, the radium-226 isotope also decays into radon-222, a gaseous, radioactive isotope and a similar human health threat. Following cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in 1998.
