Various gamma detectors can be used to monitor the air kerma or ambient dose equivalent rates in the surrounding environment. Depending on the application, GM tubes, ionization chambers or scintillators can be used as detectors.

Most monitors have internal processor control unit that converts the detector signals to the actual and average measurement values, archives the average values and ensures automatic fault detection.

Some detectors are designed for routine operation and others for accident and post-accident operations. Some models have an integrated display, all can be connected to various local and remote displays.

He-3 tubes with moderators are used to measure the ambient dose equivalent rate in neutron radiation fields in various environments, including spent fuel storage facilities in nuclear power plants, PET centres with cyclotrons, workplaces with particle accelerators, radioactive waste repositories and neutron calibration laboratories.
