Industrial sterilisation

Alanine for electron beam irradiation at 1 MeV to 4 MeV

Accurate calibration 

NPL alanine dosimeters, specifically designed for 1 MeV to 4 MeV industrial electron beams, are available pre-packaged in convenient holders.

A phantom set enables the alanine dosimeters to be irradiated alongside films for calibration. The design of the phantom assures both films and alanine dosimeters are accurately located at the same point on the depth dose curve. On return to NPL, the dose received by the alanine is determined by measuring the concentration of stable free radicals using electron paramagnetic resonance spectrometry.

Features include:

  • Convenient mailable solid-state alanine dosimeter and phantom
  • Thickness of dosimeter in beam direction: ~ 0.5 mm
  • Dose range 1 kGy to 100 kGy
  • Available on demand throughout the year
