Radicals in PTFE (polytetrafluoroethylene, Teflon) sheets irradiated by 2MeV deuteron beam in vacuum and exposed to air have been studied by ERS at 9GHz and at room temperature. An asymmetric line with a main peak of width 23±1 gauss at g=2.0174±0.0007 is observed, which is very stable under open air at room temperature. This type of centers has been concluded to be the peroxy chain radicals. The number of radicals produced is concluded to be proportional to the number of incident deuterons, the yield being 2000±420 radicals per one incident deuteron. However, the radical density comes to an upper limit of (1.36±0.11)×10^<19> radicals/cm^3, or one radical per (3820±304) C-F bonds, at a dose higher than (3.43±0.45)×10^<13> deuterons/cm^2.
