Naturally Occurring Radioactive Materials (NORM) in …

The two radium isotopes present in produced water and barite scale are 226Ra (half-life =1,600 years) and 228Ra (half-life =5.8 years). These two isotopes are produced by radioactive decay of uranium and thorium present in rocks of the oil-producing formations. The concentration of dissolved radium is therefore influenced by the abundance of ...
