The most important features of Pb1-xMnxTe(In) solid solutions are the effect of Fermi level (FL) pinning and the existence of metastable electronic states resulting in the appearance of the relaxation processes of long duration. The increase of MnTe content in Pb1-xMnxTe(In) leads to the shift of pinned FL towards the conduction band edge Ec and metal-dielectric transition at X approximately 0.05. The kinetic processes under the radiation of Pb1-xMnxTe(In) single crystals have been investigated in the temperature range 4.2-35 K. It has been found that under the composition X variation the view of kinetic curves changes qualitatively. At X
