The aim of this work was to estimate dose homogeneity inside the body during total body irradiation and to check the agreement between doses calculated and those measured in vivo for the applied method of irradiation. 30 patients were input into the dose comparison. The irradiation was performed with a Co-60 unit. Six lateral and two anterior-posterior fields were applied. Calculations and measurements were carried out for ten
transverse cross-sections representing different body parts and organs. Doses were measured with thermo luminescent, semiconductor and ionization detectors. Dose deviations inside the patient's body, along the body midline, ranged between -0.8% and + 7.9% in relation to the prescribed dose, and those outside the midline ranged between -1.6% and + 8.7%. Standard and percent deviations from the prescribed dose for the whole group of patients exceeded 10% at the neck and the lung sections only.
