Practical Exercises in Radiological Physics

Lecturer:

Tutor:

Jozef Sabol (gar.), Jana Hudzietzová

Supervisor:

Department of medical branches and humanities

Synopsis:

The target of laboratory exercises is to acquaint students with common monitors of ionizing radiation and with their use in simple experiments. Attention is paid to practical verification of functions of these monitors in different configurations: detector - radiation source. Radiation sources with very low activities will be employed to minimize irradiation of students in the experiments. Whenever possible, thanks to the highest sensitivity of the monitors used, natural radionuclides present in different materials or natural radiation background will be used in the laboratory experiments.
