IntroductionThe widespread application of electromagnetic radiation (EMR) in modern medicine requires healthcare professionals and undergraduates to be familiar with its physical and biological properties.AimThe aim of this paper was to review current literature on EMR physical principles.Materials and methodsAvailable literature on EMR has been reviewed and grouped thematically.Results and discussionThe electromagnetic spectrum is divided into radio waves, microwaves, infrared, visible, ultraviolet, X-, gamma- and cosmic rays. Electromagnetic waves (EMWs) are characterized by frequency, velocity, period of vibration and wavelength. Depending on the medium, EMR may decelerate, reflect, refract, diffract, interfere or polarize. These phenomena apply to EMWs (light waves), pressure and water waves. The wave-particle duality of radiation is widely accepted and explains its nature and mechanism of action. Principles of quantum mechanics help to predict the potential biological impact of EMR.ConclusionsFrom humble beginnings, more than 100 years ago, EMR has become an important component of modern medicine. Therefore, there exists an urgent need for education and better understanding with respect to its principles and applications.
