The Max-Planck-institute for Biophysics installed the first Gamma-Ray spectrometer in Germany. The meter based on American developments measures and analyzes the amount, kind and exact location of radioactive substances in the human body. The Gamma-Ray spectrometer was installed in a steel chamber ten feet below ground in order to prevent cosmic rays from interfering with the measurements. Meter and installation cost about 60,000 dollars.
