[The dynamics of the radiation load on reindeer on Novaya Zemlya].

The ESR analysis was carried out aiming at studying the activity of radionuclides in the dental enamel, dentin, and mandible bone tissues of reindeer of Novaya Zemlya. Doses of absorbed ionizing radiation were assessed. It was determined that the doses obtained by reindeer during underground nuclear tests were ten times higher and the activity of 90Sr was greater than those for reindeer living after the nuclear tests were suspended.

[Individual features of rat behavior: manifestations of anxiety].

Motor agitation developing in some white rats during painful stimulation of other individual decreases under the action of phenasepam (the most effective drug used in clinic in cases of neurotic alarm). This effect is accompanied by strengthening of tendency to reside in closed space. After phenasepam injection, increased not goal-directed motor activity developing against the background of reduced alimentary reactions also decreases in a part of grey rats selected by their ability to extrapolate, while their alimentary behaviour intensifies.

[Comparison of the neutron- and gamma-radiation-induced transformations of 2-deoxy-D-ribose in aqueous solutions].

Effectiveness of neutron radiation (1 MeV) was nearly twice as low as that of electrons and gamma-quanta with regard to the formation of products of radiolysis of 2-deoxy-D-ribose in aqueous solutions. A change in the dose-rate of sparsely ionizing radiation by the order of 5-6, and variation in the concentration of 2-deoxy-D-ribose from 1 to 5 mM did not substantially influence the G products of radiolysis.
