We investigated influence of cosmological GRB on the surrounding interstellar medium. It was shown that γ-radiation from the burst heats interstellar gas to the temperatures K up to the distance pc. For high density ISM, optical and UV radiation of the heated, gas can be observed on the Earth several years as a GRB's counterpart.
