    PCig of radium. For comparison most natural soils and rocks contain approximately 0.55 pCig of total radium. A uranium ore sample containing 1 weight percent uranium has approximately 3300 pCig of 226Ra. Most of the radium in older oil-field scale is 226Ra because the shorter lived 228Ra decays with a half-life of 5.
