ISO 80000-10 gives the names, symbols, and definitions for quantities and units used in atomic and nuclear physics. Where appropriate, conversion factors are also given. Radiation with quantum energies up to an including 10 eV is covered in ISO 80000-7. Radiation with quantum energies above this value is covered in this Standard. In some applications, like e.g. in far-ultraviolet lithography, radiation with energies above 10 eV is applied without intentionally making use of the ionizing property of this radiation. For these cases ISO 80000-7 is applicable.
