Among the various dosimetric techniques used for characterizing the radiation beams used in radiation therapy, the electron spin resonance (ESR) arouses increasing interest for applications in various therapy procedures [1]. Free radicals are known to be produced when a compound is irradiated with ionizing radiations. The concentration of radiation-induced free radicals is proportional to the absorbed dos e and this allows for dosimetric measurements through ESR technique which able to quantitatively determine the radical concentration [2]. Our research group has started an investigation of the ESR response of some phenols compounds for possible ESR dosimetric ap plications suitable features, such as high efficiency of radiation-matter energy transfer and radical stability at room temperature [3-5]. In this work we report the ESR investigation of IRGANOX 1076 pellets a nd thin films exposed to various type of radiation beams (clinical photon and electron beams, neutron-photon mixed field).
