The course provides basic information on detection of ionizing radiation. Summary of basic knowledge of nuclear physics necessary to understand derived from parallel course 02ZJF is the content of the first lecture. The main part of the course contain information on sources of radiation and methods of radiation detection of neutrons. Spectroscopy is lectured similarly: all kinds of ionizing radiation with a special lecture on neutron spectroscopy. Emphasis is given on physical principles of detection and spectroscopy but appropriate detection technique and its set-up is provided in an appropriate detail. Last lecture as an introduction to laboratory exercises is devoted to theory of probability and mathematical statistics with emphasis on processing of experimental data because the course on theory of probability and mathematical statistics is no more in CV of nuclear engineering. Basics of writing of scientific article is provided also to make easier writing a laboratory protocol as first student scientific text. Laboratory exercise are rather important part of the course amounting about 2/3 of the time (5-6 tasks). Students are given a problem with prepared short description and task to measure some quantity(ies) and write a protocol as scientific text (an article). Exercise is carried out in groups of maximum 3 students; protocol is written individually.
