Abstract
We derive the rate at which photons in an optically thick line are absorbed by cold dust. This rate is approximately equal to the dust optical depth to the cloud center times the rate at which the photons escape from the cloud. Our derivation is in response to a recent article by Strel'nitskii in which he incorrectly criticized our previous application of this result to models for the pumping of cosmic masers. Strel'nitskii now agrees that his criticism was unjustified.
