Abstract

Abstract: In radiobiology experiments, that usually entail unique irradiation geometries, it is necessary to know properly the absorbed doses involved. It is difficult to find them out, due to the differences between these irradiation conditions and the reference conditions in which the absorbed dose is measured by the usual ionometric procedures. The aim of this study is to check the EBT3 radiochromic film as a dosimetric system for x-ray beams used in radiobiology experiments. The film has been calibrated in different energy photon beams, so its energy independence has been proved. Afterwards it has been used to evaluate the absorbed dose in two radiobiology experiments: first one required the irradiation of flowers, while in the second, mice with implanted tumors were irradiated. In both cases EBT3 radiochromic film has shown to be a suitable tool for measuring the absorbed dose in this kind of experiments. Abstract : Highlights: EBT3 radiochromic film has been evaluated as a dosimeter in radiobiology experiments. It has been calibrated in different energy photon beams. Its energy independence on the energy beam has been proved. It has been used to evaluate absorbed doses in two radiobiology experiments.
