When using a scanning water phantom these detectors serve for beam characteristics measurement (main profiles, depth dose curve) as well as for data acquisition for isodose calculation (profile set, matrix scan).

Diode Detectors can be used with the electrometer MR 1501 and the water phantom MR 5122M using SW-package MR 7401 (Quality Control System for Relative Dosimetry)

MR 3111 ... field diode detector for X beams
MR 3121 ... field diode detector for electron beams
MR 3131 ... field diode detector for verification of light and radiation field coincidence

Detectors with a semiconductor diode serve for safety verification measurement of dose delivered into human body during radiotherapy treatment (brachytherapy and/or teletherapy).
Detectors design differs depending on the place of application (cavities or surface of body) and on the type/energy of radiation used for treatment.
In-Vivo Diode Detectors should be used with the safety electrometers MR 1402 or MR 1403
