Unformatted text preview: electromagnetic radiation include wavelength and frequency. Different types of electromagnetic radiation have unique wavelengths and frequency. By measuring these characteristics, the type of radiation can be identified. Short wavelength and high frequency are characteristic of radiations, such as gamma and x-rays. Gamma rays are the most hazardous type of radiation from sources outside the body because they can travel much greater distances through air and all types of material. Gamma rays can travel up to a mile (1.6 km) in open air and may present a significant hazard even at fairly large distances.
