Superfund Site Profile
The U.S. Radium Corp. site is located in Orange, New Jersey. From 1917 to 1926, the U.S. Radium Corporation operated a radium processing plant at the 2-acre area. Waste from the plant was disposed of on and off the facility property, contaminating the site and nearby properties with radium-226. Radium-226 emits ionizing radiation and decays into radon gas. People who are directly exposed to radiation, inhale radioactive dust particles, or inadvertently ingest radioactive particles may suffer adverse health effects in the form of an increased risk of certain types of cancer. After immediate actions to protect human health and the environment, EPA put the site’s long-term remedy in place. Groundwater monitoring is ongoing.
