The possibility of photo-transmutation of long-lived nuclide 135Cs by ultrashort ultraintense laser was analytically evaluated. The yield of 135Cs(γ,n) 134Cs was strongly dependent on the laser intensity at around 1020 W/cm2. If 135Cs were irradiated by such a laser with the intensity of 1021 W/cm2 and 10 Hz for 30 min, characteristic γ-ray counting rate was estimated to be 3 Bq.
