CHICAGO (CBS) — Tissue boxes contaminated with low levels of radioactive material, sold at Bed, Bath and Beyond, pose “no immediate threat” to the public, officials said Friday.

The Illinois Emergency Management Agency said Friday it is coordinating with federal officials and Bed, Bath and Beyond to identify and secure the tissue box holders contaminated with cobalt-60.

While they present no immediate health risk, according to a release from IEMA, the agency is working with federal officials to prevent unnecessary radiation exposure by anyone who comes in contact with them.

The contaminated items are in the Dual Ridge Boutique product line, model number DR9M. They were manufactured at a facility in India and shipped to a Bed, Bath and Beyond distribution site in New Jersey. The items were shipped to the company’s stores in 20 states, including at least two stores in the Chicago area — 1800 N. Clybourn in Chicago and 3232 Lake Ave. in Wilmette.

On Wednesday, staff from IEMA’s Bureau of Radiation Safety visited both locations where store officials had already removed and secured the entire product line from store shelves, the release said.

At the Chicago store, four tissue box holders were found to have elevated radiation levels. At the Wilmette location, three tissue box holders with elevated radiation levels were identified. Several other bath accessory items within the same product line, which had also been removed from store shelves, showed no signs of radioactive contamination.

At both stores, the contaminated items were segregated and secured to prevent further exposure to employees or customers.

As a reference of the relative risk of these items, a person who spends 10 hours within one foot of the holder would receive a dose equivalent to a single chest x-ray, the release said.

On Friday, IEMA is sending staff to seven additional Bed, Bath and Beyond stores in the Chicago area that received items in the product line since September. At this time, it doesn’t appear any of the affected items were shipped to stores in other areas of the state.

Customers who believe they may have purchased a tissue box holder from the Dual Ridge Boutique product line should contact Bed, Bath and Beyond at (800) 462-3966.
