EffMaker Calibration Software

Software for calculating detection efficiency and modelling gamma spectra with the Monte Carlo method, where calibration with reference standards is hard to do.

EffMaker can also be used to analyse how the radionuclide distribution in a sample affects the activity measurement results. The relative position of the detector and the object can be fine-adjusted, including placing the detector inside the object.

  • Calculates detection efficiency and gamma spectra in different measuring geometries using the Monte Carlo method
  • For objects such as transport containers and waste packages that can hardly be calibrated with reference standards
  • Models objects with arbitrary, including non-uniform, distribution of activity
  • Built-in patterns for tubes, cylinders, boxes, plates, angle bars and more
  • Batch calculation of detection efficiency for different detectors and objects
