METORAD
METORAD-1 represents the combination of the metal detector and the radiation indicator device what registers the radiation level and locates the metal objects the possible sources of the radiation. Both systems may be used separately.
The detection of radiation and metal objects is indicated either by sound signal through the headphone or piezo electric buzzer or followed visually by light signals on the front panels of the control units of both systems.
Metal detector locates the large metal objects such as strong bozes, canalization well traps up to 80 cm deep and the little metal objects such as nails, coins up to 15 cm deep. The metal detector has the automatic background setting. Radiation indicator detects Beta- and Gamma-radiation. The sensor in hermetic body is fixed to the coil of the metal detector.The level of the radiation is indicated by the colour of signal lamps.
