The efficiency and correctness of the procedure of 
calculation of the optical characteristics of selectively radiating 
and absorbing media proposed by the authors earlier and making it 
possible to take into account with a high degree of accuracy the fine 
structure of the absorption line is illustrated with the example of 
calculation of a number of standard problems of radiative transfer. 
The reliability of calculation of the absorption coefficient (averaged 
over a finite spectral interval) of a selective medium is evaluated 
based on the comparison of the results obtained to the experimental 
and theoretical data given in the literature.
