Improvement of quality in the evaluation of radium isotopes 224,226,228Ra in oil scale samples
Elevated concentrations of the radium isotopes 224,226,228 Ra exist in the scale and produced water in oil exploration. The activity concentration of 226 Ra was calculated from 186.2 keV peak with no usual spectral interference of 185.7 from 235 U. The activity concentration of 228 Ra was calculated...
