The operational dosimeter is required, in addition to your personal dosimeter, for working in Limited Stay and High Radiation Controlled Radiation Areas. For specific activities or for optimisation purposes, the Radiation Protection Group can also recommend using these dosimeters outside these areas.
The operational dosimeter is sometimes referred to as: active dosimeter, electronic dosimeter or DMC.
The operational dosimeter features a direct dose display, audible indication of the radiation level and alarm functions when thresholds for dose or dose rates are exceeded.
It can either be assigned permanently to a person or can be used in 'pool' mode. For the latter, the dosimeter is not assigned to a specific person and can be shared amongst colleagues. It will be attributed to the user by the reader station when switching it to ON.
