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
