| Abstract: | A method for the determination of 226Ra, 228Ra and 210Pb in water samples of mining regions by measuring the  and  intensities with the help of a liquid scintillation counter is presented. The high-energy part of the -particle spectrum emitted by 210Bi is used for the determination of 210Pb content in the samples. An attempt is also given to explain the radioactive disequilibrium between 226Ra and 210Pb in the samples investigated. |
