It is described the simple practical model of express-estimates of the ion-electron emission (IEE) induced by the fast ion fluxes in the emitter of radioisotope source of current. It is taken into account the analytical approximations for medium stopping power and electrons inelastic mean free path, the source of suprathermal electrons (SE) generation and the probabilities of SE arriving at the film surface and their passage through surface potential barrier. The model may be used for computer simulations of processes in solid-state plasma of emitter films in the radioisotope battery.
