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.
