Landauer’s IPLUS dosimeter

IPLUS®: a state-of-the-art dosimeter

beta

X
IPLUS is a passive dosimeter ready to use. It incorporates OSL technology developed by LANDAUER and used by 200 dosimetry laboratories worldwide. Robust, compact and light, IPLUS has been tested by the Laboratoire National Henri Becquerel (LNHB), an independent laboratory, and has shown the following performances:
  • Excellent energy response for Hp(10) photon: from 15 keV to 6 MeV from 0 to ±60°
  • Excellent energy response for Hp(0.07) beta: from 0.24 to 0.8 MeV from 0 to ±45°
  • Linearity deviation < 5% from 0.05 mSv to 10 Sv for Hp(10) and Hp(0.07)

Technical Specifications

Ergonomy

IPLUS can accommodate for two additional detectors in the same housing:

  • NEUTRAK® (neutron dosimeter of CR-39 type)
  • Imaging® to determine the exposure conditions in static or dynamic conditions
Developed by our R&D team in France, the IPLUS personal dosimeter can measure Hp(10) and Hp(0.07) dose equivalents. IPLUS complies with standard EN 62387:2016. Its characterization by an independent laboratory (LNHB) even shows metrological performance significantly higher than the standard requirements.
  • Linearity deviation < 5% for the whole measuring range
  • Energy dependence < 11%
