According to the specification to the contract № 1-567/11-2008 on 31.01.2008 conducted research needed to develop technology of detecting units of ionizing radiation on the basis of crystal CdZnTe. With the use of mathematical modeling method is developed for determining the parameters of charge transport in CdZnTe detectors based on their dosimetric characteristics. The main parameters are accurate calculation of dose rate created by the source of gamma radiation at a point where the detector is placed, and precision measurement of the detector counting rate at a given threshold of discrimination. The method of computer simulation study the influence of noise on the sensitivity of CdZnTe detectors operating in pulse mode, and determining acceptable level of equivalent noise charge (ENC) in dosimetry devices. Based on the amplitude spectra obtained from simulation, calculated the dependence of noise sensitivity investigated CdZnTe detectors spectrometric, and dosimetric quality assurance in gamma-ray energy 662 keV for different levels of discrimination signal. Developed design layouts detecting units of exposure dose rate (EDR) of gamma radiation: full spectrum - working in the Accounting (pulsed) mode; "emergency" - for measuring large doses employed in the Current (analog) mode. Database designed to measure the dose rate of gamma radiation on the premises and in the industrial nuclear power plant as a part ASKRB and individually using standard electron-physical apparatus. Past Forecasts dosimetric characteristics of the database. Developed database based on CdZnTe will meet modern requirements for radiation monitoring devices for nuclear power plants. A technology of detectors SdZnTe for full spectrum, emergency units and spectrometric detection. According to the developed project carried out a partial configuration of equipment research areas for the production of detectors of CdZnTe. Compiled list of equipment for research and acquisition of industrial output of the detecting units for 2009. Product Description popup.authors Вєрьовкін О.О. Захарченко О.О. Кутний Д.В.
