| Measure Name | Radon |
|---|---|
| Year Range | 2003-2013 |
| Measure |
The proportion of homes with an operating radon mitigation system for persons living in homes at risk for radon exposure. This measure is expressed as a percentage. It is calculated for each year by dividing the cumulative number of single family dwellings (SFD) with an operating mitigation system by the number of SFDs estimated to have a radon level ≥4pCi/L, which is EPA’s action level. |

| Trends and Most Recent Estimates | In 2013, 15.0% homes at risk for radon exposure had an operating radon mitigation system. |
| Healthy People 2020 Target | Increase the percent of at-risk homes with an operating radon mitigation system to 30.0%. |

| Measure |
We present exposure data on the 95th percentile of the population, representing people with the greatest exposure. The 95th percentile level means that 95% of the population has concentrations below that level. Public health officials use such reference values to determine whether groups of people are experiencing an exposure that is unusual compared with an exposure experienced by the rest of the population.

| Trends and Most Recent Estimates | In 2013 to 2014, the 95th percentile for urinary (creatinine corrected) concentration of arsenic among persons aged 6 years and older was 52.0 µg/g of creatinine. |
| Healthy People 2020 Target | Reduce exposure to arsenic in the population, as measured by blood and urine concentrations of the substance or its metabolites, to 35.28 µg/g of creatinine. |
