In this tutorial I will focus on several topics which are sometimes neglected, or shadowed, in textbooks, but are essential for a deeper understanding of radiation processes in accelerator physics. They include the notions of longitudinal and transverse formation lengths in the process of radiation, coherent versus incoherent radiation, effect of correlations of particles' positions on radiation, fluctuations of the spectrum, and radiative reaction forces. Importance of these concepts is illustrated with analysis of synchrotron, undulator and transition radiation. I try to avoid complicated equations throughout the lecture relying instead on order of magnitude estimates.
