Equivalent to the NE BP6 / AP2, there are three versions of these 16 in2 (100 cm2) window probes available:

  • Alpha only (Zinc sulphide layer).
  • Beta only (Plastic scintillator).
  • Alpha/ Beta (Zinc sulphide bonded to a plastic scintillator).

The use of a plastic scintillator avoids the traditional use of anthracene in this application, with a comparable response.
