Dosimetric data obtained from different measurement techniques of 10 MV small circular photon beams of 12.5, 20, 30, and 40 mm diameter were studied. The effects of lack of lateral electronic equilibrium and steep dose gradient were noticed even when measurements were performed with a small volume (0.02 cc) ionization chamber. From an examination of the… CONTINUE READING
