| The distribution of
the count rate of neutrons (per second) near the Earth’s surface for two
directions: towards the Earth and away from it, is studied using the
experimental data, obtained in Moscow during 1996. The analysis shows that
the mathematical approximation of the neutron count rate distribution can
be described by a sum of two functions: a Poison distribution and a
log-normal distribution. This is in agreement with the two known sources
of the total neutron flux near the Earth’s surface: generation of
neutrons in nuclear interactions of high-energy cosmic ray particles with
the Earth’s atmosphere and neutron production in the Earth’s crust.
The log-normal distribution describes the contribution of the Earth’s
crust to the total neutron flux near the Earth. Therefore, these dynamic
processes in the Earth’s crust change the parameters of the log-normal
distribution. |
