For activation of isotopes 127J, 140,142Ce and 238U the brake radiation from electrons of the linear accelerator was used. The threshold of detectability of elements has reached from 5 to 15 g/g for a sample by the area 1 cm2. The coefficients of diffusion in a material of a grain and on borders were measured which for temperature of pressing 910grad.C and pressure 100 MPa have made 3.5 · 10-19 cm2/s in a grain and 1.2 · 10-8 cm2/s on borders of grains.
