Whenever people heard the word ‘radiation’ they get the perception of ionizing radiation. Hearing the word radiation, many people think about alpha, beta, and gamma radiation. No doubt many information are available about the characteristic properties those ionizing radiation due to their hazards as well as fruitful applications. However, people should also think about the hazards and benefits of nonionizing radiation. Nonionizing radiation including ultraviolet rays, visible light, infrared rays, microwaves, radiowaves and acoustic waves are gaining more attention due to their use in latest technologies. Our mobile phones, microwave ovens, television and radio networks all use non-ionizing radiation. Moreover, many useful equipment and techniques like MRI, Ultrasound, and echocardiography use non-ionizing radiation. Due to tremendous increase and demand of the technology based on non-ionizing radiation it is important to further investigate the basic properties, harmful effects and benefits of non-ionizing radiation. The purpose of this special issue is to report latest developments and investigations in the area of hazards and benefits of nonionizing radiation.
