Project summaryThe main goal of the Project is to create a new generation of polymer scintillators (PSc) with high operational characteristics (light output, radiation stability, fast reply, appropriate optical and luminescence characteristics, selectivity to definite type of ionizing irradiation etc.). This Project is a development of ISTC Project #193 (1995-97) in which the mechanism of radiation degradation of PSc has been studied in detail and new film and bulky PSc have been developed with considerably improved the radiation resistance.
Following basic results will be obtained. in the Project:
- Samples of new film PSc will be obtained with the light output level of about 300% relative to commercially available polystyrene-based standard PSc (to our knowledge, this would be absolutely the best level among all the organic scintillators);
- Samples of new film scintillators with the radiation resistivity level of 6000 Mrad on the base of polymer matrices possessing own radioluminescence in a visible region;
- The essentially new type of the bulky PSc on the base of luminescent nanocomposites will be developed with the high overall level of characteristics (high conversion efficiency, high absorption coefficient of definite type irradiation, high radiation stability etc.);
- Series of new high efficient radiation resistant bulky PSc will be developed on the base of modified polymer matrices with good permeability to oxygen, including PSc selective to definite type irradiation.
- Unique experiments will be carried out using nanoparticles which are expected to give new important information concerning the processes of the energy conversion of ionizing irradiation into optical emission;
PSc to be developed can find application as:
- High efficient detectors for express analysis and the control of radiofarmaceutic preparations for a long living alfa - active contamination;
- Detectors for high accuracy analysis of radioisotopic markers distribution in a medicine diagnostics;
- High efficient detectors for radiation monitoring of environment and the potential sources of radioactive pollution;
- Luminescent screen - amplificator for X-ray display with high resolving power;
- Screen - amplificator for flaw detection and fluorography;
- In design and development of reliable control devices intended for detection, identification and account of the quantity of nuclear materials including the tasks of:
- affording high efficient control of the correspondence to Agreements about limitations for widening the nuclear arms;
- control of safety of storage, annihilation and use of nuclear materials, preventing nuclear terrorism and smuggling and stealing nuclear materials;
