Our experimental results with amifostine and cystamine, both of Czechoslovak production, indicate that not only intravenous or intraperitoneal injections but also intramuscular or subcutaneous administrations of protectors induced a good protective effects against gamma irradiation on the level of radiosensitive tissues as well as on the level of whole organism of different small and high laboratory animals.

Analysis of extreme Solar events during long-term measurements on board of aircrafts
Ploc, Ondřej ; Spurný, František
Extreme Solar events can rapidly change radiation field in atmosphere of the Earth. These events are hardly predictable; calculations of their effects are at the beginning. One of the applicable methods is direct measurement by means of the active detector long-term placed on board of the aircraft. Results of semiconductor spectrodosimeter Liulin are discussed in this contribution. Liulin was repeatedly placed on board of aircraft during years 2001, 2002, 2005 and 2006. One GLE and several Forbush decreases have been registered during this period.
