On the basis of the kinetic equation for interaction of the electromagnetic radiation quantums with rarefied gas the time dynamics of approach to equilibrium thermal radiation of quantum distribution function and density of radiation energy is investigated. It is shown, that in a seen interval of electromagnetic waves this process lasts some micro seconds. The deduction of the kinetic equation of interaction of quantums with atoms of rarefied gas is submitted. Some consequences from this equation are investigated.
