This study describes the three-dimensional dosimetric characteristics of total body irradiation by our dedicated irradiation unit, which consists of two modified 4-MV linear accelerators mounted opposite each other, providing a field size of 220 cm x

The absorbed doses on the central axes of narrow beams (radii 0.07-2.5 cm) of 6-MV x rays have been studied by experiments and Monte Carlo simulations. The measurements were made in a geometry used for irradiation of intracranial lesions. For radii l
