Solar cycle variations of MIR radiation environment as observed by the LIULIN dosimeter

Evaluation of the neutron radiation environment inside the International Space Station based on the Bonner Ball Neutron Detector experiment

“…This result is consistent with the albedo neutron measurements reported by Dudkin et al (1992), and the neutron radiation environment inside the ISS predicted by Armstrong and Colborn (2001), which is mainly due to solar-activity variation, namely the anti-correlation of GCR flux and trapped-proton flux with solar activity (e.g. Dachev et al, 1999).…”

Effects of solar activity on noise in CALIOP profiles above the South Atlantic Anomaly

“…This anticorrelation is due to heating of the exo-and thermosphere during maximum solar activity, which leads to a higher neutral density in the altitudes below affected by the SAA (e.g., Qian et al, 2006). This increases the absorption and deflection of trapped particles, resulting in a lower particle flux compared to when the solar activity is minimum (Dachev et al, 1999). Thus during maximum solar activity the flux of energetic particles below CALIOP is smaller.…”

Overview of the Liulin type instruments for space radiation measurement and their scientific results

“…3) was launched to the Russian segment (RS) of the ISS in September 2005. It contains four MDUs with control and interface units and displays and was used in the Service Radiation Monitoring System of the RS of the ISS (Dachev et al, 1999b). The following information can be displayed: current dose in μGy h −1 , current event rate (flux) cm −2 s −1 , accumulated dose mGy initiated by the "Switch ON".…”
