Electromagnetic radiation represents energy transmission through an immaterial medium through a flow of energy particles or quanta of energy. When passing through the material medium, there is an interaction with the medium through which they pass, and energy is transferred to the particles of the material medium. Ionising radiation (JZ) is electromagnetic radiation consisting of EM - --waves or particles with kinetic energy sufficient to ionise the substance they pass. During ionisation, orbital electrons are ejected from the atoms of the environment as negative ions and positive ions are formed from the rest of the particles. The ions formed in this way disturb the biochemical processes in the cells, which can lead to disturbances in their functioning and division and even to the occurrence of diseases, such as tumours. The effect of ionising radiation is reflected in the impact on proteins, lipids, carbohydrates and nucleic acids. The following can be recognised as occupational diseases: acute radiodermatitis, acute radiation sickness, acute radiation cataract, chronic radiodermatitis in case of exposure to ionising radiation for at least ten years, regular radiation cataract in case of exposure to ionising radiation for at least five years, malignant diseases and damage to the hematopoietic system. It is necessary to educate the entire population about the consequences that ionising radiation has on human health, provide complete protection to workers who work in radioactive radiation zones, apply all preventive and protective measures against the effects of ionising radiation in the workplace, and provide adequate, timely and professional assistance to all workers who were exposed to ionising radiation.
