In this work the possibility of using PTFE as a detector of dosimetric EPR-systems for control of radiation technologies is considered. A series of experimental results confirming the principal possibility of using PTFE-based detectors in high-dose dosimetry of ionizing radiation have been obtained.Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 20-38-90239
