Use of PIXE, PIGE, XRF for the decision of ecological problems in the NSC KIPT

Full text: The National Science Center 'Kharkiv Institute of Physics and Technology' (NSC KIPT) is the largest research establishment of Ukraine. Since 70 years in NSC KIPT nuclear-physical methods of analysis on beams of ions were developed. Now there are some electrostatic accelerators in the Institute that are used for the purposes of research of matter. The analytical complex 'Sokol' is developed and built on the basis of the small-sized electrostatic accelerator on energy 2 MeV that is delivered to other organizations. Methods of PIXE, PIGE, RBS, XRF are used in NSC KIPT for solving many of problems; however, one of priority directions are ecological researches. Works on mapping bed rocks of some regions of Ukraine and Russia are ongoing; with such development, geo-information systems are now performed. Special interest is present in regions where large industrial targets or objects of nuclear power are located. In addition to element analysis radioactive nuclide samples of bedrock are investigated. The methodology of performance of work from sampling before realization of analysis and building of maps is described. Examples of performance of similar researches for concrete regions of the country are effected. (author)
