| The features of the absorbed depth-dose distribution (DDD) on boundaries of two contacting materials and material with air irradiated with an electron beam (EB) were predicted by simulation with the software ModeRTL (Modeling of the radiation-technological lines (RTL)). Validation of DDD prediction with dosimetry was fulfilled on the industrial RTL with linear electron accelerator LAE 13/9 at the INCT, Warsaw. Simulation and measurement of boundary effects of DDD were carried out for targets irradiated by scanning EB with energy 10 MeV on moving conveyer. The irradiated materials were represented as parallelepipeds with all sizes greater than range of electrons in material. Cellulose Triacetate (CTA) dosimetric film (FTR-125) in form of strips inserted between materials and air in parallel with an axis of EB was used for dosimetry. Such irradiation setup allows to receive the complete curve of DDD on the boundary of contacting materials by one dosimetric film. The physical regularities for DDD on the boundary of contacting materials predicted by simulation methods were experimentally confirmed. Investigation of those anomalies is necessary in practice to estimate the quality of an irradiation performed on RTL at realization of various industrial EB processing. |
