Health Effects of Radium
Radium is a radioactive element that increases cancer risk, particularly bone cancer. It accumulates in bones because the body treats it like calcium. The EPA estimates that drinking water with 5 pCi/L of radium over a lifetime poses a 1 in 10,000 cancer risk.
How to Remove Radium From Drinking Water
The most effective treatment for radium removal is Reverse Osmosis or Ion Exchange. Look for filters certified under NSF 58 standards.
