Synopsis:

The goal is to make students familiar with the important and specific topic of measurement and dosimetry of neutrons as particles with specific character of interaction with a matter.

It deals with neutron sources (radionuclides, neutron generators, nuclear reactor), characteristic features of neutron interactions, methods based on nuclear reactions with neutrons, methods based on recoiled nuclei, the time-of-flight method, neutron selectors and monochromators, activation methods, methods of integrating neutron dosimetry, possibilities of use of various methods, calibration of neutron dosimeters and other dose and dose rate measuring instruments.

Requirements:

Knowledge of nuclear and radiation physics as in the subject Nuclear and radiation physics 1, 2 in the bachelor course.

Syllabus of lectures:

1.Neutrons, presence and basic properties.

2.Neutron sources based on radioisotopes and/or accelerators.

3.Neutron sources based on fission.

4.Basic interactions of neutrons in human tissue.

5.Absorption of neutron energy in human body.

6.Fundamental of neutron detection and dosimetry.

7.Methods of neutron detection and dosimetry based on nuclear interactions.

8.Methods of neutron detection and dosimetry based on neutron moderation.

9.Passive neutron dosimeters.

10.Generalized concept of dosimetry.

11.Individual neutron dosimetry, including accidents.

12.Other topics related to neutron dosimetry.
