Describe and understand the principles of radiation protection and the characteristics of the main radiological investigations to avoid risks and complications
Ionizing radiation: classification. Coolidge tube: components, materials and functions. X-ray image. Concept of contrast in radiodiagnostics. Applications of traditional radiology. Radiobiology: basic concepts on ionizing radiation. Excitation phenomenon, photoelectric effect and Compton effect. Interactions photons matter. Law of quadratic radiation dispersion. Dose concept, quality factor and dose equivalence. Dosimetry. Radiation damage. Cellular and tissue radiosensitivity, radioresistance. Ellinger cellular radiosensitivity scale. Somatic damage in the professionally exposed subjects. Stochastic and non-stochastic effect. Expected effects depending on the time of uterine irradiation of the conception product. Sources of ionizing radiation: natural and artificial. Radiation protection. Classification of areas: controlled and supervised. Classification of workers.
