Abstract
The effects of acute irradiations of a mixed pine and birch forest in spring and autumn with a high power point-type gamma radiation source (1180 TBq Cs-137) have been described. Radiation dose relationships fo r numerous response reactions of woody and herbaceous plants (growth a nd development of organs of woody plants, cytogenetical, physiological and biochemical changes in trees, reproductive potential of plants, d amage and dying off of the forest as a biogeocenosis on the whole) hav e been calculated. Post-radiation recovery of the forest was investiga ted. Changes involving the secondary reactions related to radiation da mage and death of the trees are presented. A model for radiation damag e of forests has been designed. Examples are given on the usage of thi s model in the description of radiation effects in forests in the even t of accidental releases of radionuclides into environment.
