In this work, mathematical modeling of a complex of processes occurring in a tungsten target under irradiation with high-energy electrons with an energy of 100 MeV: an electromagnetic shower, the production of photo-neutrons, and particle transport along the target, damage from neutrons of the subcritical assembly. It was found that the greatest contribution to the rate of damage formation in a tungsten target give the elastic scattering of high-energy electrons on nuclei.

The inhibition of multiplication of one poliomyelitis virus by a poliomyelitis virus of another immunologic type has been established by using tissue cultures of monkey testes. The degree of interference varied from none, to partial, to complete, depending upon the time between inoculation of the interfering and the challenge viruses, and the amount of each virus inoculated. Reciprocal interference was demonstrated between Types 1, 2, and 3 poliomyelitis viruses. Under conditions which resulted in complete suppression of the growth of one poliomyelitis virus by another, interference by poliomyelitis virus with the multiplication of four antigenically distinct "orphan" viruses and of three antigenically related strains of Coxsackie virus could not be demonstrated. Poliomyelitis virus rendered non-infective by formalin or by irradiation with high energy electrons or with ultraviolet light, or treated so that only traces of residual active virus remained, failed to interfere with the propagation of active homologous virus.

Main Input

In this work, the rate of radiation damage production in a uranium target of the neutron source at NSC KIPT un-der electrons irradiation with an energy of 100 MeV was estimated. The contribution of elastic and inelastic proc-esses is determined: high-energy electrons and gamma quanta, photo-neutron production, fragments arising from photo-fission, damage from neutrons. It was found that the main input into damage production in a uranium target give fragments of photo-fission.
