Gamma ray waste water radiation monitor has been improved by using multichannel analyzer. Maximum permissible concentrations of125Iare one thousandth lower than51Cr.This condition, the radioactive waste water cannot be pumped out occasionally. Gamma ray energy spectrum is measured by microcomputer based multichannel analyzer by which125Iphoto-peak counts is separated from other radionuclide counts. Also detecting vessel is washed with pressured fresh water to prevent contamination.
