Orthovoltage machines produce X-rays with a power of 150-500kVp, while megavoltage machines (cobalt-60 and linear accelerators) emit photons of energy greater than 1,000,000 volts.
Electron beam therapy is well adapted as well as orthovoltage radiation therapy (100 kV).
Treatments such as superficial and orthovoltage X-rays (photons) therapy, brachytherapy ([sz]-rays using phosphorus-32[sup][22]/strontium-90, a-rays using cobalt-60[sup][25]/iridium-192),[sup][30] and electron beam ([sz]-rays)[sup][36] were all proven to be helpful, even at different levels, suggesting a great improvement in postoperative irradiation protocols happened in last few decades.
