The structure of nonthermal radio emissions in the Galaxy at a frequency of 150 MHz

It is assumed that there is a stationary source of electrons near the center of the Galaxy and that there is no intense 'radio halo'. A three-component model of nonthermal radio emission comprising a stationary nucleus, an inhomogeneous radio disk, and shell-like objects is found to give satisfactory agreement with observational data. The directions in which minima are observed are given. Assuming that the brightness temperature of the extragalactic component of the cosmic radio emission is 60-90 K, it is possible to ignore the Galaxy's radio halo. At latitudes greater than or equal to 30 deg, the role played by loop objects within 1 kpc of the sun is significant. When an allowance is made for the anisotropy of the galactic magnetic field, this distance is 15-17 kpc, and the disk becomes thinner (average thickness, 0.8-1.0 kpc). The metagalactic component of the cosmic radio emission at 150 MHz is 90 K when no allowance is made for the anisotropy of the galactic magnetic field and 60 K when an allowance is made.
