Experimental detector modules (DM) are developed to be integrated in the systems of radiation monitoring of NPP of Ukraine. .

Such DM, base on CdTe and CdZnTe sensors, operating in a count mode, satisfy the requirements for radiation monitoring instrumentation. DM, operating in a current mode, are intended for measurements of high-intensity gamma-radiation at the monitoring system of the fuel containing masses at «Shelter» in Chernobyl and for estimation of radiation loads for patients at radiation therapy and screening..

Detector modules for system of gamma-ray control ↑

Detector module BDBG-01T with semiconductor CdZnTe sensor was developed for dosimetry of X-and gamma-radiation.
It consists of:
  • CdZnTe detector 6×6×3 mm3
  • charge sensitive preamplifier
Its principal technical and competitive advantages are:
  • high sensitivity to radiation at small size
  • high processing speedВысокое
  • low energy consumption

The State Bureau of Standards of Ukraine has registered the specifications TU U 22651643.001-99 for our CdZnTe detectors.
