摘要：

The C-13 and F-19 NMR spectra of the original and irradiated polytetrafluoroethylene samples were studied in the range of gamma radiation doses of up to 50 kGy. In this range, the F-19 NMR spectrum width increases linearly with an increase in the absorbed dose. It is concluded that it is possible to monitor technological doses by the NMR method using polytetrafluoroethylene as a detector.
