Why should you conduct a dosimetry workstation study? 

The workstation study is part of an occupational risk assessment approach for the health and safety of workers within the framework of the directive 2013/59/Euratom of 5 December 2013.


The employer has three main duties:

  1. conduct a predictive assessment of collective and individual doses workers are likely to receive during dosing operations;
  2. define targets for collective and individual doses for the operations concerned;
  3. measure and analyse the actual radiation doses received during the operations and compare them to the predicted doses.

The exposure risk analysis can be complemented by an analysis of other risks at this workstation.

The Radiation Protection Expert are generally responsible for these measures and analyses, which he should record such as in an exposure sheet.  He also recommends personal protective equipment and collective protective equipment adapted to the workstation.

The exposure sheet enables the classification of the exposed workers into Category A or B.

The delimitation of restricted zones enables the selection of ambient dosimeters and individual dosimeters required and adapted to access these areas.

The workstation study is part of the ALARA policy of the company, as it allows mapping of the most dosing operations and improvement of operational protocols (implementation of personal protective equipment or collective protective equipment, reduction of exposure time, isolation, etc.)

It must be performed in realistic conditions of the workstation, i.e. in areas more likely to be occupied by workers.

LANDAUER guides you through your workstation studies as follows:

  • Implementation of the study protocol with the help of our technical assistance: Our Radiation Protection Experts guide you through the implementation and selection of dosimeters best suited to your needs.
  • Orders and shipping of dosimeters.
  • Return of dosimeters to LANDAUER for analysis.
  • Transmission of study dose reports.

The IPLUS®, MONORING® and VISION® dosimeters are particularly adapted to your workstation studies:

Dosimetry workstation study with IPLUS dosimeter


The IPLUS dosimeter is used for workstation studies in photons and betas on the following wearing areas:

  • chest, in front or on personal protective equipment in Hp(10) or Hp(0.07)
  • wrist, ankle via the bracelet
  • background measurement via the area dosimeter
Neutron dosimetry workstation study with IPLUS & NEUTRAK dosimeter


A Neutrak detector can be incorporated in the IPLUS to measure additionally neutron doses in Hp(10).

Workstation study for extremities dosimetry


The MONORING dosimeter is used for workstation studies in photons and betas in Hp(0.07) at the fingers. Up to ten dosimeters, one per finger, can be used.

Workstation study for lens of eye dosimetry

The VISION dosimeter is especially recommended for workstation studies in photons Hp(3) for the lens. It can be placed:

  • in front or behind lead or unlead glasses
  • on the side or in the middle of the glass

    Glasses for VISION dosimeter

  • on a headband close to the lens.
