N2  - The thesis work presents the results of theoretical studies of different scenarios for the propagation
and the radiation of ultrarelativistic particles depending on the environment determined
by the magnetic and low energy radiation fields.
First, using the analytical solution of Boltzmann equation in the small-angle approximation,
we have accurately calculated the angular, energy, and time distributions of the ultrahigh
energy protons, gamma rays produced by synchrotron radiation of secondary electrons and
positrons, and secondary neutrinos from the source of cosmic rays embedded in the magnetized
environment of the level of B ? 10^(?9) G.
The second part considers the scenario explaining TeV gamma radiation from distant blazars
by secondary gamma rays produced by cosmic rays along the line of sight in the weak magnetic
field of the level of B ? 10^(?15) G. We have studied the possibility of detection of TeV radiation
from blazars with redshifts greater than z = 1.
Finally, the last chapter of the work is addressed to the radiation of charged particles in the
extremely strong magnetic fields of compact objects such as pulsar and black hole. We have
studied the synchrotron and curvature radiation regimes and transition between them showing
the strong sensitivity of radiation spectra on the pitch angle.
