title: [A gamma spectrometer for measurements of radionuclide concentrations in biological samples].
abstract: A CAMAC spectrometer with a scintillation detector was developed for radioactivity measurements in environmental and biological samples. The spectrometer allows one to use an additional single channel analyser for rapid isotope control and to use simultaneously a number of ADCs in a concurrent mode. A technique of efficiency calibration is described which simulates the volume sample measurement with a point reference source of photon radiation and a cylindrical water-equivalent plate-stack phantom. The minimum detectable radionuclide concentration was found to be equal 5.10(-5) Ci/kg.
