One of key factors of cryogenic systems is a heat transfer from room temperature. In some cases a heat transfer by radiation is dominant. A general calculation for heat transfer by radiation is given in this paper. Assumtion used is that all surfaces are of diffuse graybody. A heat transfer by radiation for straight dewars and its dependence on surface treatment of wall are discussed and compared with experimental results.
