We consider issues related to the determination of integral characteristics of the scattering phase function for media with a highly forward directed scattering function. We show that, as a rule, the standard method of calculation of the average cosine of the scattering angle does not take into account the contribution that is important for scattering in the direction of small angles. We present a technique that makes it possible to obtain necessary corrections for the integral scattering characteristics in this case.
