Pulse-echo method in the frequency range of 37.5—232.5 MHz in LiF crystals at T=300 K has been used to study the behaviour of dislocation decrement Δd(f) at variations of the residual strain value and X-ray radiation in the range of 0—400 R. It has been found out that with the increasing doses o...
