Relative Resistances of Microorganisms to Cathode Rays

The Biomechanical Effects of 1.0 to 1.2 Mrad of Gamma Irradiation on Human Bone–Patellar Tendon–Bone Allografts

“…1,16 Known pathogens include HIV, hepatitis, bacteria, and fungus. 8 Non-sporeforming bacteria are susceptible to 0.5 Mrad of irradiation, 25 while bacterial spores may require up to 2.1 Mrad. 12,18,32 Yeasts and molds require intermediate doses of approximately 0.8 Mrad.…”

“…21,23,33 Lower doses (2.0-3.0 Mrad) still demonstrated increased elongation and decreased stiffness, maximum force, strain, and maximum stress. 1,8,14,16,22,34,37 Doses in this range also disrupt collagen organization 25,38 along with cleaving polypeptide bonds. 15 Ideally, lower irradiation levels (1.0-2.0 Mrad) may not compromise biomechanical properties for the sake of pathogenicity.…”
