Model 44-9 Exposure Filter Kit – Ludlum

The Model 44-9 Exposure Filter Kit (Ludlum) is an expansion on the Model 44-9 Pancake GM Detector. It is an energy compensation filter that flattens the energy response to facilitate measuring exposure.

Model 44-9 Exposure Filter Kit features:

  • flattens the response to within ±20% referenced to 137Cs (662 keV) over an energy range of 33 keV to 1.2 MeV
  • easy to mount and remove
  • filter can be purchased separately or together with a Model 44-9 Pancake GM Detector
