title: [Leakage radiation from the RUM-17 x-ray apparatus outside the main beam].
abstract: The leakage radiation exposure rate was measured outside the main beam of the RUM-17 orthovoltage therapeutic x-ray unit by a 1000 cm3 ionization chamber. The results were corrected according to the detector volume averaging. It has been shown that the relative exposure rate normalized to the beam axis exposure rate does not depend on voltage and filter thickness. It can be represented by the same equation. The most important sources of non-used radiation are leakages from the shield (near the treatment cone connection) and scattering in the plexiglass window of the treatment cone.
