When it comes to things to worry about in your daily life, radioactive radon gas probably isn’t at the top of your list. However, using data compiled by Data Pandas, we can see which states have the highest radioactive (pCi/L) levels in the U.S. Without smell, color, or taste, radon can be very dangerous, and the Environmental Protection Agency recommends taking action to reduce the levels.
To produce its findings, Data Pandas collated data from all 50 states. They ranked each state based on the average amount of radon in “picocuries per liter (pCi/L),” the traditional way to measure radioactivity. With this in mind, let’s see which states rank the highest and require immediate action to reduce radon levels as soon as possible.
