INTRODUCTION: The discovery of X-rays in November 1895 by Roentgen opened a new chapter in the scientific development and pretty soon it became clear that these rays can be useful for diagnostics and treatment. The most frequent use of X-rays is related to their ability to pass through matter. The main fields of application of the rays are medicine, industry, checks of goods and packages and scientific studies. Modern medicine constitutes approximately 80% of the overexposure. The contribution

The quality of the medical services depends to a great extent on the accurate and timely diagnoses set through different methods using also ionizing radiation. The exposure of the patient should be reasonably justified and optimized but cannot be limited. The risk of exposure to high doses of radiation is justified only if this is appropriate for the diagnosis or the treatment. Each overexposure, including medical irradiation, is related to certain radiation risk. Radiation protection is a means to apply the measures intended to protect the health from ionizing radiation-related risks. It is essential to know the benefits and risks of the medical procedures.
