For a long time now, surgery followed by irradiation has been the preferred therapy in the treatment of keloids. Radiation can be administered by means of X-rays (energy level less than or equal to 100 KV), electrons (energy level less than or equal to 5 MeV) or 192Ir wires. The choice of one of these methods depends on the availability of suitable facilities within a short period of time (less than 24 hours postoperatively), and the possibility of adapting the irradiation field quickly and easily to the scar. A further criterion is the dose received by underlying organs possibly, especially the ovaries of women of child-bearing age. It consists of primary and secondary (scattered) parts of radiation and was measured in two standard field sizes for the various types of radiation so as to allow a rapid evaluation. Apart from the types of radiation mentioned above, such measurements were also carried out for 125I seeds. With a field size of 20 x 1.5 cm2 and a surface dose of 10 Gy, ovaries at a depth of 10 cm in the central beam will receive a dose of between less than 1 m Gy in electron therapy to around 1 Gy in X-ray therapy (100 KV).
长期以来，手术联合放疗一直是瘢痕疙瘩治疗的首选疗法。放疗可通过X射线（能量水平小于或等于100千伏）、电子（能量水平小于或等于5兆电子伏特）或铱192线进行。选择这些方法中的一种取决于短时间内（术后24小时内）合适设备的可用性，以及能否快速轻松地使照射野与瘢痕匹配。另一个标准是潜在器官可能接受的剂量，尤其是育龄女性的卵巢。它由辐射的原发射线和散射线组成，并针对各种类型的辐射在两种标准射野大小下进行测量，以便快速评估。除上述辐射类型外，还对碘125粒子进行了此类测量。在射野大小为20×1.5平方厘米且表面剂量为10戈瑞的情况下，中心射束中深度为10厘米处的卵巢在电子治疗中接受的剂量小于1毫戈瑞，在X射线治疗（100千伏）中约为1戈瑞。
