Jan 1b63a Gas Switching Waveguide Electron Tube, Sealed, NIB. Manufactured February 1983
In 1983, this 1b63 was manufactured with at least 1 microcurie of Cobalt-60. After three decades, its activity should have diminished to less than 0.0193 microcuries. Although the remaining activity is undetectable with a Geiger counter, it can still be analyzed using Radiacode 101, 102, or Gamma Spectroscopy. When employing a Radiacode, the most accurate results can be obtained by using Lead shielding and the background subtraction feature.
