They are produced by x-ray units operating at voltages in the 35–60 kV range, and therefore have energy in the 35–60 keV range (see External beam radiotherapy for an explanation of the maximum and mean energies as a function of voltage). They are useful in radiation therapy for the treatment of various benign or malignant skin problems, and have a useful depth of a couple of millimetres – certainly not more than 5 mm.〔Robin Hill, Brendan Healy, Lois Holloway, Zdenka Kuncic, David Thwaites and Clive Baldock, ("Advances in kilovoltage x-ray beam dosimetry" ), ''Physics in Medicine and Biology'', vol 59 no 6 〕 By convention, the electron-gun voltage is used to characterize X- and gamma-ray beams, whilst electron beams are characterized by their energies in electronvolts. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Superficial X-rays」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
