In the last decades several research laboratories have shown an increasing interest aimed at extending the applicability of ESR-dosimetry to radiotherapy with different types of radiation beams. ESR is a spectroscopic method for investigating the structure and dynamics of such paramagnetic species. The concentration of radiation-induced free radicals is proportional to the energy released inside in the medium. Our research group has started an investigation of the ESR response of some phenols compounds for possible ESR dosimetric applications suitable features, such as high efficiency of radiation-matter energy transfer and radical stability at room temperature. In particular, the phenoloctadecyl−3−(3,5−di−tert.butyl−4−hydroxyphenyl)−propionatephenoloctadecyl−3−(3,5−di−tert.butyl−4−hydroxyphenyl)−propionate gave interesting results. In this work we report the ESR investigation of phenols exposed to clinical photon and electron beams.
