title: Inactivation cross section of ions for dry enzymes and viruses.
abstract: In this note, a semi-empirical analytical formula for the inactivation cross section of ions for dry enzymes and viruses is developed based on the delta-ray theory of track structure. Using the experimental characteristic dose of gamma rays, the cross sections are calculated and compared with experimental results. The average ratio of the experimental to the calculated cross section is 0.96 +/- 0.17.
