The University of Nevada Reno Radon Education Program provides test results that were completed by Nevada homeowners from 1989 to the present. The results have been compiled for each county by zip code and a corresponding geographical information systems (GIS) map based on zip codes has been designed.
The Nevada Bureau of Mines and Geology has incorporated the radon data into a hazards map which is available online at https://gisweb.unr.edu/MyHAZARDS/
The geologic units found in Nevada are presented with the Nevada radon test results so that a relationship can be illustrated. See the interactive map and then select the possible radon risks, radon potential and test averages.
Each layer is described as follows.
Geologic units with possible radon risk: Certain rock types, including granite and shale, commonly have higher than average uranium content and are associated with elevated radon concentrations. This map illustrates where granite and shale are exposed at the ground surface; however, elevated radon levels can occur in numerous other geologic settings. Site specific testing is the only way to determine local radon concentrations.
Radon potential: The radon hazard category shows radon potential, radon average, and geologic units that could be associated with higher radon risk. Radon potential and averages were compiled as part of the Nevada Radon Education Program and results are based on independently tested homes from 1989 through 2015, not scientific sampling. Radon levels are measured in pCi/l and are calculated according to zip code. The geologic units layer features certain rock types, including granite and shale, that commonly have higher than average uranium content and are associated with elevated radon concentrations. This layer illustrates where granite and shale are exposed at the ground surface; however, elevated radon levels can occur in numerous other geologic settings. Site specific testing is the only way to determine local radon concentrations.
Radon averages:
1.99 pCi/L
2.00-3.00 pCi/L
4.00-13.95 pCi/L
The clickable map provides zip code area, population and average radon concentration.
