  • Page 16 Make sure that the red marking lines directly join the measuring range of the next SOLITRAC 31. Mount the SOLITRAC 31 in such a way that the detector tube is directly in the radiated area of the source container. Mount the SOLITRAC 31 preferably side by side and make sure that no detector tube is hidden by another sensor.
  • Page 17 If these measures are not sufficient to maintain the max. ambient temperature, you could consider using the water or air cooling system we offer for SOLITRAC 31. The cooling system must also be included in the calculations for the measuring point. Contact our specialists regarding the dimensioning of the cooling.

  • Page 32 The normal reduction of source activity through radioactive decay is thus taken into account. The SOLITRAC 31 requires this information for the automatic decay compensation. This ensures error-free measurement over the entire lifetime of the gamma emitter - an annual recalibration is not neces- sary.
