Sapwood of Alnus rubra and Pinus ponderosa was sterilized by impregnation with ethylene oxide, steaming at 121 degrees C, or gamma-radiation at three dosages (2.5 X 106, 5.0 X 106, and 107 rad), and then exposed to two brown-rot and two white-rot fungi. Gamma radiation at 2.5 X 106 rad is a suitable alternative to the other methods of sterilization. A small loss of wood occurs at all three radiation doses.
