Abstract
The room-temperature radiation electric conductivity of 15 polymer mat erials under continuous irradiation with electrons (60 and 75 keV) and protons (7.7 MeV) in the dose rate interval 1-10(4) Gy/sec was invest igated. The parameters A(m), DELTA, and delta were determined for all polymers studied. It is shown that the radiation electric conductivity is produced by both the free-charge mechanism (in PETP, PS, PEN, PPMI ) and the heminal mechanism (in PP, PTFE, PMMA, and other) mechanisms. Conductivity of a mixed type is observed in HPPE. The Rose-Fowler-Vai sberg theory is modified for the case of heminal electric conductivity .
