Service Description: This digital layer contains polygons (vector format) of portions of California designated as having high, moderate, low, or unknown potential for homes to exceed the U.S. EPA recommended radon action level of 4.0 picocuries per liter in indoor air. Only a portion of California is covered by the studies included in this dataset.
