Lindsay Light and Chemical Company Information
Location
West Chicago, Illinois

Lindsay Light and Chemical was a commercial processor of monazite sands, which yield several commercially valuable products, including the radioactive metal thorium. The Manhattan Engineer District and then the Atomic Energy Commission purchased thorium from Lindsay; AEC contractors purchased a variety of products from this firm as well. Documents indicate that the firm supplied thorium to the MED and AEC through at least 1953. The facility received a source material license from the AEC in 1956, and it continued to process radioactive materials for commercial purposes until 1973.
During the period of residual contamination, as designated by the National Institute for Occupational Safety and Health and as noted in the dates above, employees of subsequent owners and operators of this facility are also covered under the Energy Employees Occupational Illness Compensation Program Act.
