IPLUS® and Neutrak®: High performance integrated neutron dosimeter


LANDAUER® provides you with IPLUS & Neutrak, a unique dosimeter incorporating the Neutrak detector in the IPLUS  badge. The dosimeter is used to measure X-rays, beta and gamma radiation, as well as thermal, intermediate and fast neutrons.

Provide your team with a two-in-one dosimeter:

  • the lightest and most compact dosimeter on the market (17 g, 35 x 74 x 10 mm)
  • the only certified neutron dosimeter in France covering the energy range of thermal neutrons at 16.5 MeV
  • tested by the National Physical Laboratory (NPL), an accredited and independent laboratory in the UK
  • easy to wear and ready for use at the chest, wrist or ankle
  • compliant with EN 62387:2016 (IPLUS) and ISO 21909-1:2015 (Neutrak) standards
