Radiation: definition and classification
Ionizing and non-ionizing radiation. Electromagnetic and corpuscular radiation.
Mode of production of X-rays and radionuclides (x-ray tube, nuclear reactor, cyclotron).
Causes of radiation exposure (accidental, health, professional, natural).
Gamma photon origin and corpuscular radiation.
Radioactive isotopes, natural and artificial radioactivity, half-life. Radioactive decays.
Physical interactions of ionizing radiation with living matter.
Excitation and ionization. Photoelectric effect, Compton and pair formation.
Dosimetric units. Exposure dose, absorption dose. Equivalent dose.
Measurement of radiation dose.
Direct and indirect radiation action.
Chemical damage, radiolysis of water and production of free radicals. Oxygen effect.
Molecular and cellular damage.
Physical factors that condition the biological response: EBR, LET, radiation quality factor.
Effects on cellular populations, survival curves.
Cellular and tissue radiosensitivity.
Stochastic effects and graded effects.
Pan-irradiation, gastroenterology, hematologic, CNS syndrome.
Principles of radiation protection.
Business organization in protecting the health of those exposed to radiation.
Obligations of the employer.
Classification of work areas: Closed area, controlled area and supervised area.
Exposed workers of category A and category B.
