The lecture „Radioactivity III“ is aimed to explain gamma decay, interaction of gamma rays with matter, energy spectra, radiation attenuation, and protection against radiation.                                                                                                                                                                                                                         

Radioactivity II.

Author: Katarína Kozlíková

The lecture „Radioactivity II“ is aimed to explain alpha and beta decays, interaction of these particles with matter, energy spectra and range of particles, protection against radiation.                                                                                                                                                                                                                                   

Structure of Matter From Biophysical Point of View

Author: Katarína Kozlíková

The lecture „Structure of Matter From Biophysical Point of View“ is aimed to give a brief introduction to some applications of physics at microscopic level in medicine. It explains the fundamental problem of science, gives an overview of important stages in structure analysis, explains different structure and forms of matter, physical interactions, general properties and characteristics of matter, Heisenberg uncertainty principle, basic properties of elementary particles, the principle and usefulness of Schrödinger equation.

Radioactivity

Author: Katarína Kozlíková

The lecture „Radioactivity“ is aimed to explain basic terms as radioactive isotopes, natural and artificial radioactivity, law of radioactive decay, half-life of decay (physical, biological, effective), mean life-time, activity and connected formulas and physical units.

Dosimetry.

Author: Katarína Kozlíková

The lecture „Dosimetry - Measurement of Ionising Radiation“ is aimed to explain the term dosimetry and the basic quantities characterising the radiation from the aspect of their biological effects that allow to measure and to quantify them. Terms as dose, absorbed dose, absorbed dose rate, integral dose, equivalent dose, effective dose, kerma, kerma rate, exposure, exposure rate and connected formulas and physical units are explained.
