The radiation chemistry of various dense astrophysical environments has been subject to many laboratory investigations which dealt with the radiation of simple gas or ice mixtures with UV radiation or high energy particle irradiation. Certainly the experimental irradiation time is always by many orders of magnitude shorter than the time scales of the simulated astrophysical system. To obtain comparable total absorbed doses of energy, high dose rates, respectively current densities of radiation, have been applied in the simulations. This paper deals with problems in the application of experimental data on the chemistry of the astrophysical environments arising by the difference in dose rate.
