InLight®: OSL-based dosimeter badge


InLight dosimeter badge provides X, gamma and beta radiation monitoring with Optically Stimulated Luminescence (OSL) technology.

InLight can be used for occupational, area, environmental and emergency radiological monitoring, in any kind of facilities. More than 2 million workers in the world are monitored daily with OSL LANDAUER dosimeter badges:

  • Ready to use
  • Robust, compact and lightweight dosimeter badge
  • Fully personalised and customisable

LANDAUER dosimetry laboratory solution includes InLight dosimeter badges, readers, annealers, software and so on.
