In brief review, the general survey of particle accelerators' design, construction and applications in various fields of science and technology is given. The development of accelerator physics was initiated by Professor Soltan immediately after foundation of Institute of Nuclear Research. These works oriented initially on accelerator for research, were after extended on numerous applications of accelerator radiation sources in such important areas as medicine, radiation technology, nondestructive testing, agriculture and environmental protection. Due to this broad spectrum of different types of accelerators' design, it was necessary to master the fundamental directions of accelerator physics and technology: theory, computation methods, metrology and production basis. As the result of this efforts, nearly 90 of electron and ion accelerators were produced - half of them were exported. At present nearly 70 accelerators are operating in Poland, about 20 of them are of foreign origin.
