Tutor:

Supervisor:

Department of Dosimetry and Application of Ionizing Radiation

Synopsis:

The course introduces students to the metrology, including its legislative framework. Fundamental and general concepts of the field (calibration, verification, legally controlled measuring instruments, measuring standards, measurement accuracy) are explained. Further, the methods of atomic and nuclear physics quantities determination (activity, source emission, radiation exposure, absorbed dose) are discussed in detail.

Requirements:

The exam is oral. Each student draws a pair of questions from a list that is available in advance and covers the course material.

Syllabus of lectures:

1. Fundamentals of metrology

2. Introduction to legal metrology, act and decrees, measurement standards, legally controlled measuring instruments, metrological traceability chain

3. International System of Units, quantities and units of atomic and nuclear physics

4. Data evaluation, measurement accuracy, measurement errors and uncertainties

5. Applications of proportional counter in radionuclide metrology

6. Coincidence method for determination of activity

7. Internal counting, liquid scintillators, TDCR

8. Electrostatic and calorimetric method of activity measurement

9. Secondary standardization of activity, gamma spectrometry, ionization chambers in current mode

10. Radiation exposure standardization, free-air ionization chamber

11. Dose and kerma standardization, calorimetric method, cavity ionization chamber
