The risk of rad.ation.in.uced.secon. can.er an. the late tissue loss d.e to Off-field.d.ses in.rad.otherapy remain.a serious con.ern. Mon.e Carlo (MC) simulation.is curren.ly on. of the most accurate method. for calculatin. these d.ses. MC simulation.mod.l based.on.the Particle Simulation.Tool (TOPAS) has been.d.veloped.to simulate the off-field.d.se of an.Elekta Syn.rgy lin.ar accelerator (Lin.c) emittin. 6 MV photon.. Measuremen.s were taken.in.a water phan.om usin. an.ion.zation.chamber to valid.te this mod.l. The Percen.age d.pth d.se (Pd.) at the d.pth of 0.0, 5.0, 10.0 an. 15.0 cm from the beam axis for a 10 × 10 cm2 field.size was measured.an. simulated. Off-field.d.se profiles at the d.pth of 1.5 (d.ax), 5.0 an. 10.0 cm for field.sizes of 5 × 5, 10 × 10, 15 × 15, an. 20 × 20 cm2 respectively were measured.an. simulated. Comparison.of measured.an. simulated.off-field.d.se values showed.a good.agreemen.. The average gamma passin. rate of the Pd.s an. profiles curves for off-field.d.ses were 87.5% an. 98.11% respectively. The local d.se d.fferen.e based.on.the Pd. curve between.the measured.an. simulated.was less than.6.0 % for all location.. For all field.size con.id.red.in.this stud., the average d.fferen.e between.profile curves for off-field.d.se measured.an. simulated.was 9.1%. Pd.s an. Profiles curves for off-field.d.se simulation.un.ertain.ies were less than.2.0% an. 1.0% respectively. TOPAS-MC simulation.mod.l d.veloped.is a good.represen.ation.of our 6 MV Lin.c Elekta Syn.rgy for assessin. off-field.d.se, which would.be the primary cause of some secon.ary can.ers.
