Unit to characterize the energy spectrum used in radiotherapy. For electrons, the maximum energy is given in MeV. For photons, the maximum acceleration voltage is given in MV or kV, although those are not units of energy.

Explanation of the columns that may appear on this page:

Level	A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System	The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code	The code (used as the code in the resource instance)
Display	The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition	An explanation of the meaning of the concept
Comments	Additional notes about how to use the code
