Neutrons from thunderstorms at low atmospheric altitudes and related doses at aircraft

Drozdov A., A. Grigoriev, (2013), Neutrons from thunderstorms at low atmospheric altitudes and related doses at aircraft, Journal Of Physics: Conference Series, 409, 012246, doi:doi:10.1088/1742-6596/409/1/012246

Abstract

We conduct a simulation of thunderstorm neutron flashes at the lowest atmospheric altitudes below 10 km. The neutron generation mechanism is based on the nowadays conventional idea of possibility for photonuclear reactions to proceed on the atmospheric components owing to TGF photons. Our modeling includes generation of neutrons from TGF and their further propagation with account of interaction with background nuclei. Using the calculation results we investigate the neutron flux properties with respect to problem of their registration, and predict the radiation environment caused by thunderstorm neutrons on altitudes of civil airflights. It is shown, that good conditions for the neutron flashes observation are provided from the 3 km altitude, and, possibly, the neutrons can be registered at ground level. We also found that thunderstorm-neutron-related effective dose can reach the value of 0.5 mSv in the region close to the TGF source if it is located at an altitude of 10 km.
