n-type germanium samples irradiated with fast reactor neutrons with a fluency range from 2 × 1016 up to 1 × 1020 cm−2. As a result of irradiation, n-Ge samples are converted into p-type Ge. The dc conductivity is measured in wide temperature range from 1.5 up to 300 K. Insulator metal transition occurs at irradiation fluency 5 × 1018 cm−2. The Bohr’s radius of localization (aH) is obtained and found to be equal to 43 Å. Mott variable range hopping and Shklovskii-Efros percolation models are applicable in the present data.
