title: [Radiation-induced changes of circadian dynamics in the behavioral reactions of rats in the "open field"].
abstract: The interaction of daily motor activity rythm within daily changes of early transient neurological disorders (ENTD) symptoms has been evaluated. The highest frequency of five ENTD symptoms was mainly observed in that daily periods when behavior reactions were minimal. A difference was distinguished in circadian radiosensitivity of some behavior reactions in "open field" (gamma-irradiation 60Co, 62.5 Gy). The most radiosensitive ENTD symptoms were "vertical set", "immobility" and "motion on the spot", characterized emotional state and orienting-locomotor animal reactions. Certain changes of orto- and paraphases of these behavior reactions biorythms due to irradiation have been revealed.
