In view of the neutron flux enhancements observed in thunderstorms, a contribution of thunderstorm neutrons to atmospheric radiocarbon (isotope 14 6 C) production is analyzed in connection with the archaeometry. Herein, estimates of neutron fluence per lightning electromagnetic pulse in regions with severe thunderstorm activity, at which a local rate of the 14 6 C production is comparable to the observed rates, are shown to be consistent with the measured magnitudes of thunderstorm neutron fluence. At present, available observations of atmospheric neutron and parent gamma ray flashes correlated with thunderstorms do not allow making final conclusions about thunderstorm contributions to 14 6 C production. For this, numerous studies of high-energy phenomena in thunderstorms are required, especially in the tropical belt where the thunderstorm activity is especially severe and where the 14 6 C production by galactic cosmic rays is almost independent of the solar activity disturbing the Earth's magnetic field shielding the Earth from cosmic rays. Plain Language Summary Decay of radiocarbon accumulated in fossil biota is widely used in archaeometry. A capture by atmospheric nitrogen nuclei of neutrons, produced by cosmic rays, is causal to the radiocarbon production. In view of that thunderstorms produce neutrons their contribution in the radiocarbon production is analyzed. In regions with severe thunderstorm activity, evaluated neutron numbers per unit area (fluence) per lightning required for a rate of the radiocarbon production by thunderstorms to be comparable to the measured rate magnitudes are consistent with the measured magnitudes of thunderstorm neutron fluence. Available data on thunderstorm neutrons and parent to them gamma ray flashes do not allow making final conclusion about the thunderstorm deposition in the radiocarbon production. For this, numerous observations are required, especially in tropics where the thunderstorm activity is extremely strong and where the radiocarbon production is almost independent of the solar activity disturbing the Earth's magnetic field shielding the Earth from cosmic rays.
