Abstract Objective To study the feasibility of killing all Anthrax samples by neutron and to work out an effective way in killing Anthrax spore. Method We use MCNP to build a mode and to simulate energy deposition in Anthrax spore per neutron then estimate how much time it takes to kill all Anthrax sample. We also work on the relationship between neutron energy deposition in the anthrax sample and the thickness of the reflector, materials of the reflector, and the area of anthrax sample. Results In this paper, computer simulated data of the largest energy deposition per neutron is 5×10-4MeV/g which appears in situation like:using graphite as reflector, neutron tube for the neutron source, anthrax floor area (10×10) cm2, and 5cm between neutron source and the surface of anthrax. The calculation shows that, for a neutron tube it only takes 20 minutes to kill all the anthrax spores. If using the 1014n/s yield of the neutron tube just ten seconds or longer to reach the lethal dose of anthrax spores. Conclusion To kill the Anthrax spore by neutron is of high efficiency and research value.
