This digital layer is intended for use by county staff to identify those portions of the county area where homes are more likely to have indoor-air radon concentrations exceeding the U.S. EPA recommended radon action level of 4.0 picocuries per liter. This digital layer should assist them in identifying areas where indoor-radon testing should be encouraged and public awareness programs may be beneficial. |

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. |

This map layer is intended for use by staff to identify portions of the county where homes are more likely to have indoor-air radon concentrations exceeding the U.S. EPA recommended radon action level of 4.0 picocuries per liter (pCi/L). The four radon zone categories indicate the likelihood of a home having indoor-radon concentrations at or above the 4.0 pCi/L action level: High (>20 percent), Moderate (5 to 19.9 percent), Low (< 5 percent), and Unknown (insufficient data to estimate the radon potential). The map layer does not provide specific information about the indoor-radon concentration of a home at any given location within a zone. The only way to accurately determine the indoor-radon concentration within a home at any location is by testing the indoor-air of that home. This can be done by the homeowner using inexpensive testing devices which are sent to commercial laboratories for evaluation or by certified radon testing professionals. This map layer is designed to be used at a map scale of 1:100,000 and not more detailed scales. At this scale it is not unusual for geologic unit boundaries (and, consequently, corresponding radon zone boundaries) to have accuracy limitations of plus or minus tens to several hundred feet and sometimes more. Consequently, radon zone classifications are less certain for locations nearer zone boundaries. CGS does not guarantee the accuracy of radon potential limitations for property parcels based on this map. |
