Abstract :

The use of radiation beams in radiotherapy requires effective dosimetry to protect the patient from potential dangerous effects of irradiation. In vivo dosimetry allows the control and precise evaluation of attributed dose during radiotherapy treatment by using accurate dosimeter. Some previous studies have revealed that the alanine/EPR system has interesting dosimetric properties. In this study, we have analyzed the dosimetric properties of alanine irradiated by 6 MeV electron beams which is usually used for radiotherapy treatment. Irradiation doses undertaking vary from 0-20 Gy. EPR measurements show that the rate of produced free radicals is proportional to the absorbed dose, whereas the minimal detectable dose is 1 Gy. A small quantity of alanine is efficient to elaborate pellets for dosimetric purpose. Furthermore, the free radicals created after irradiations are stable during the period of storage.
