  • Page 8: Principle Of Operation

    When the intensity of the radiation drops below a defined value, e.g. due to damping, then the POINTRAC 31 switches. The measuring principle has proven itself well under extreme conditions because it measures contactlessly from outside through the vessel wall. The measuring system ensures maximum safety, reliability and plant availability independent of the medium and its properties.

    Stick with the normal sequence of the menu items as closely as pos- sible. Setup Setup - Isotope In this menu item you can adjust the POINTRAC 31 to the integrated isotope in the source container. For this purpose, check which isotope is integrated in the source container. You can find this information on the type label of the source container.
  • Page 26 The normal reduction of the emitter activity is hence considered through the radioactive decay. The POINTRAC 31 requires this information of the automatic decay compensation. This ensures an interference-free measurement over the complete life time of the gamma emitter - an annual recalibration is not necessary.
