e/Orthovoltage X-rays

Information
has gloss	eng: Orthovoltage X-rays are produced by X-ray generators operating at voltages in the 200–500 kV range, and therefore an energy in the 200–500 keV range (see external beam radiotherapy for an explanation of the maximum and mean energies as a function of voltage). When used to treat patients, radiation oncologists find that they penetrate to a useful depth of about 4–6 cm. That makes them good for treating skin, superficial tissues, and ribs, but not for deeper structures such as lungs or pelvic organs.
lexicalization	eng: Orthovoltage X-rays
