In particular, the problems of radiation monitoring of the environment are described - observation, collection, processing, transfer, storage and analysis of information on the state of the environment. Described and classified means of registration and dosimetry of ionizing radiation. The comparative analysis of methods of obtaining and properties of CdTe and CdZnTe crystals is given. Technologies of obtaining, processing and creating X-ray and gamma radiation sensors are presented. It is shown that sensors of sensors on CdTe are very small due to the small dimensions of the working surface. It has been established that during prolonged exposure to radiation on CdTe crystals the noise (by several times) increases due to the creation of thermal carriers in the volume of the crystal, which leads to a decrease in resolution Recommendations on the use of work results - it is recommended to continue this work in the direction of creating devices using these materials, it is necessary to increase the sensitivity of the sensor on the basis of CdTe increase the working surface area by creating planar film multilayered structures, as well as, to reduce noise use thermoelectric cooling structures for temperature creation is not higher than 10 0С. Field of application - Detectors sensitive to X-ray and gamma radiation used in the basic sectors of the economy: nuclear energy, environment, safety, transport, medicine, and others. Devices using X-ray and gamma radiation detectors are required to monitor the environment, determine the contamination of radionuclides of territories, materials, objects, including to detect and prevent the illegal movement of radioactive materials Product Description popup.authors Rodionov Valerii Ye.
