Measurement of ionizing radiation

Enrollment in year 3.

Passed problem-solving examination is a prerequisite for the theoretical part of the examination.

Accelerator systems. Ion sources, review of accelerators, transport of charged particles.

Radioactivity. Basic notions (activity, decay time, statistics, alpha, beta and gamma radiation, isotopes, radioactive series), sources of radiation (natural and man-made isotopes, cosmic radiation).

Interaction of radiation with matter. Heavy charged particles, light particles, photons, neutrons.

Detectors. Shockley-Ramo theorem, ionization chambers, proportional counters, multi-wire proportional counters, drift chambers, Geiger-Mueller counter, semiconductor detectors, scintillation detectors and photomultipliers.

Particle identification. Detectors of energy loss, time-of-flight, Cerenkov detectors.

Radiation dosimetry. Biological effects of radiation, deterministic and stochastic radiation effects, exposition dose, absorbed dose, equivalent and effective dose.

Application. Activities in Slovenia, visit of our national laboratory (MIC - Institute J. Stefan).

The purpose of the subject is to give basic knowledge of physical principles which concern ionizing radiation. It is a prerequisite for further study of experimental nuclear and particle physics and medical diagnostics and therapy.

Knowledge and understanding: The syllabus gives basic understanding on measurement od ionizing radiation and interpretation of collected data.
Application: Education covered by this subject is a necessity for everyone working in laboratories dealing with any kind of radioactive sources.
Reflection: Expert in measurement science applies the bottom-up approach to tackle a specific problem. This is by far the best approach to demanding technical challenges.
Transferable skills: Skillful handling of complex data can be rewarding in many areas outside nuclear and particle physics.

Lectures, tutorials, homework and consultations.

2 written tests (mid-term and end-term) applied towards the problem-solving examination, problem-solving examination
Theoretical examination
grading: 5 (fail), 6-10 (pass) (according to the Statute of UL)
