Abstract
The influence of acute gamma radiation on four physiological character istics of lichens was investigated. Membrane permeability in irradiate d thalli of Cladomia arbuscula, Cetraria islandica and Hypogymnia phys odes increased considerably compared to controls. The nitrogen content in Peltigera aphthosa appeared to be stable to acute gamma radiation. Up to 1000 Gy there was no essential decrease in respiration intensit y in H. physodes and P. aphthosa or of peroxidase activity in P. aphth osa.
