Abstract

Three types of samples, bacteriophage T7, isolated phage DNA, polycrystalline uracil thin films were prepared in sandwich form that were closed vacuum-tightly with inert gaseous environment. The response of the samples to the following selected space environmental conditions was investigated: temperature (- 20 - +40°C), vacuum, short wavelength UV irradiation. Uracil thin layer samples proved to be insensitive for temperature. In the vacuum chamber the structure of the samples in sandwich arrangement did not change. Irradiation with germicidal and Deuterium lamps caused a decrease in the optical density of the uracil layers and the decrease showed a saturation tendency in both cases. The dose-effect curves at germicidal lamp possess a saturation level at a lower optical density than at Deuterium.
