Nevada “My Hazards Map” Includes Radon

by Margaret Henderson

A collaboration between the Nevada Radon Education Program and the Nevada Bureau of Mines and Geology has produced a “My Hazards Map” which includes radon, along with other categories of hazards (fires, floods, earthquakes) with choices of base layer (satellite imagery, streets, etc.).

The interactive map with multiple hazard layers can been seen at
https://gisweb.unr.edu/MyHAZARDS/ The American Geosciences Institute Critical Issues termed it the “map of the day” on Twitter on June 6.

Radon potential and averages were compiled through collaboration with the Nevada Radon Education Program using results from independently tested homes from 1989 through 2015 (not scientific sampling). Radon data is shown as radon potential, and radon average, and geologic units that could be associated with higher radon risk, such as shale and granite, which have higher uranium content are shown. The geologic layer illustrates where granite and shale are exposed at the ground surface; however, the disclaimer notes that elevated radon levels can occur in numerous other geologic settings and testing is the only way to know the radon concentration.

Radon potentials are given in breakouts of:
• 0-9.99%
• 10-19.9%
• 20-100%

Radon levels are measured in pCi/l and are calculated according to zip code.
Radon averages are given in groupings of:
• 0-1.99
• 2-3.99
• 4- 16.53

The map allows the user to turn off and on various layers, to measure distances and to save the findings to a pdf. Work to produce maps was supported by the Nevada State Division of Public and Behavioral Health through a grant from the U.S. Environmental Protection Agency.
