Radon Levels in the USA

This is a follow up post about the radon levels in the United States of America. As mentioned in an earlier post, radon is formed when uranium breaks down into radium, which breaks down into radon. Radon is absorbed by the soil and ends up in water wells and home foundations. According to the Environmental Protection Agency (EPA), radon levels shouldn’t exceed 4.0 pCi/L (pico curies per liter). The map below shows the radon levels by color – yellow representing Zone 1; counties where average indoor radon screening levels are less than 2pCi/L, orange representing Zone 2, counties where average indoor radon screening levels are between 2 and 4 pCi/L, and red representing Zone 3, counties where average indoor radon screening levels exceed 4pCi/L.  According to the National Radon Defense, the best way to know the radon level in your home is to test for it.

Radon is a colorless, tasteless and odorless gas that can cause lung cancer. According to the University of Georgia College of Family and Consumer Sciences, radon is the second leading cause of lung cancer in the U.S., after tobacco. Radon is formed when uranium breaks down into radium, which breaks down into radon. Radon is absorbed by the soil and can enter homes through the foundation and well water systems. The map below shows the percentage of homes tested with radon levels 4.0 pCi/L and above. The data is from homes which volunteered to test their homes for radon.

CCCounty-Immunization-Map

Contra Costa County in California unveiled a map this week that labels vaccination rates for every day-care and kindergarten program in the county.

The Contra Costa map shows five kindergarten programs and 22 day-care centers where more than 10 percent of students are not fully vaccinated because their parents have requested a personal belief exemption
