Ionizing radiation can be applicable in medicine in the field of diagnosis and treatment. Early and accurate diagnosis of disease through imaging techniques and advanced treatments contribute to longer life expectancy and improving the quality of human life.
According to international standards, worldwide 20% of the collective radiation dose of the population of all the natural and artificial sources of radiation comes from medical applications, which are the main source of population exposure to artificially produced radiation. This figure is 50% in developed countries. In particular, man receives radiation when subjected to radiological diagnostic tests (e.g., CT scans, mammograms), nuclear medicine diagnostic tests (e.g., Positron Emission Tomography - PET / CT) and interventional radiological procedures (e.g., vascular and cardiac surgery, pacemaker placement). In addition, during the healing processes (radiotherapy and nuclear medicine treatments) patients exposed to high doses of radiation, which are suitably designed for each individual patient in order to achieve the optimal therapeutic effect.
The diagnostic reports are characterized by sufficiently low doses to patients that are sufficient to provide the necessary clinical information. Conversely, the therapeutic exposures are less frequent and include much higher doses to treat the disease or relief of symptoms.
The purpose of radiation protection in diagnostic tests is to ensure that it is given the lower dose to the patient with the best diagnostic results, while the therapeutic practices (nuclear medicine, radiotherapy) that is given the correct dose, while protecting healthy tissues. At the same time, the purpose of radiation is to protect workers, the public and the environment.
