Abstract
In order to monitor the radiation environment, radiometric instruments were accomodated aboard the “Mir” and most of the “Salyut” space stations. These instruments registered the neutron flux in the energy range from thermal to several MeV. This paper briefly describes the instrument and contains results of the neutron flux measurements performed during 1975–1980. The results reported here were compared with measurements obtained on board the OGO-6 orbital observatory. Measurement data obtained aboard the Salyut-6 space station allowed determination of the integrated neutron flux distribution (mainly local) in the region of the South Atlantic magnetic anomaly and estimation of the albedo neutron flux on the geomagnetic equator (0.06 ± 0.02 cm-2 s-1) and on the 45° and 60° geomagnetic latitude (0.43 ± 0.1 and 0.58 ± 0.15 cm-2 s-1, respectively). The angular distribution of albedo neutrons is described by the following expression: f(θ) = 1 + 0.615 cos4θ.
