Gamma irradiation is a simple and effective method to sterilize wood and stop fungal decay. Unfortunately, little is known of the effect of this method on other properties of wood. The purpose of the present study was to establish the relationship between irradiation dosage and the elastic characteristics of wood. The longitudinal and transverse dynamic MOE of five wood species were measured periodically between subsequent irradiation phases. There was a steady decrease in MOE as gamma dosage increased, for all species included. The extent of this decrease was different between the examined species. The experimental data suggests that the MOE of lower density species decreases more sharply than that of higher density ones. Interpolation between the experimental data points shows that the necessary dose for fungal sterilization does not significantly reduce the MOE of the species involved in this study.
