Electron Beam Irradiation on Novel Coronavirus (COVID-19): via a Monte-Carlo Simulation

The novel coronavirus pneumonia triggered by COVID-19 is now raging the whole world. As a rapid and reliable killing COVID-19 method in industry, electron beam irradiation can interact with virus molecule and destroy activity. With the unexpected appearance and quickly spreading of the virus, it is urgently need to figure out the mechanism of electron beam irradiation on COVID-19. In this study, we established virus structure and molecule model basing on the detected gene sequence of Wuhan patient, and calculated irradiated electron interact with virus atoms via a Monte Carlo simulation that track each elastic and inelastic collision of all electrons. For present the characteristics of irradiation damage on COVID-19, atoms ionizations and electron energy losses are calculated and analyzed by regions. And we simulated the different situation of incident electron energy for evaluating the influence of incident energy on virus damage. It is found that under the major protecting of envelope protein layer, the inner RNA suffers the minimal damage. The damage for a hundred nm virus not always enhances with irradiation energy monotonicity, for COVID-19, the irradiation electron energy of the strongest energy loss damage is 2 keV.
