Web3 aug. 2024 · The spectrum is divided into eight categories, organized in order of increasing energy and decreasing wavelength. From low frequency to high frequency, here are the eight kinds of electromagnetic radiation: Long radio waves Radio & TV waves Microwaves Infrared rays Visible light UV rays X-rays Gamma rays WebIn general, the UV portion of the spectrum is not included in the ionizing region because UV at wavelengths less than 295 nm are filtered by the atmosphere. UV at these short wavelengths, however, can be produced in some types of lasers, so would, under these circumstances, be considered ionizing.
WebRadiation dose units are limited to ionizing radiation photons and ionizing particles (Tables 23.1, 23.2, and 23.3). Typically, ionizing radiation photons are defined in terms of energy expressed in multiples of the electron volt, keV (thousand electron volts) or MeV (million electron volts), rather than wavelength (λ) or frequency (Hz).
