The course summarizes the basic objectives and content of ionizing radiation metrology. It deals with the interpretation of radiation quantities and units in metrology. It summarizes the theoretical and experimental foundations of metrology, the determination of basic parameters of radiation. Lectures are supplemented with basic summary of relevant legislation and regulations.


Required prerequisities are 16ZDOZ12, 16DETE.

Syllabus of lectures:

1. General metrology.

2. Legal metrology, units, metrology law.

3. Metrology in the Czech Republic.

4. Standardization of the activity, proportional detector, Townsend process.

5. Liquid scintillator, coincidence method.

6. Preparation of the sources.

7. Standardization of the neutron sources, Mn- bath.

8. Secondary standardization of the activity, radionuclide calibrators.

9. Data evaluation, uncertainty A and B.

10. Calorimeter as absolute method for doze, kerma and exposition measurement.

11. Standardization of the exposition and kerma, air-free chamber, cavity chamber.

12. Photon beams for secondary standardization, X-ray spectra, structure of the laboratory.

13. Measurement of the ionization current.

Syllabus of tutorials:

1. Data processing, uncertainty of type A, B, notions sample mean, sample standard deviation, activity determination.

2. Absolute method of measuring dose kerma and exposure, air-free chamber.

3. Books for secondary metrology, X-ray, gamma ray spectra description, implementation, organization of work.
