The radon-hazard-potential map of Utah (M-149)

By: B. D. Black

Radon is a naturally occurring radioactive gas formed by the decay of uranium which can be found in small concentrations in nearly all geologic materials. When radon is inhaled, its decay products are a significant cause of lung cancer. Radon gas has long been recognized as an occupational health hazard to workers in uranium mines, however the hazard from accumulation of radon gas at lower concentrations in buildings has only recently been recognized. The indoor-radon hazard depends on a variety of geologic and non-geologic factors.

Although the influence of non-geologic factors such as building construction type and weather is difficult to measure geologic factors that influence indoor-radon hazards can be quantified. A numerical rating system based on geologic factors (uranium concentration, soil permeability, and ground-water depth) was developed to assess and map the relative radon-hazard potential for the state.
