Abstract Methods and parameters of calculating organ doses from immersion in a radioactive cloud released by nuclear facilities were investigated.T he effects on the organ doses of some facto rs such as the g round surface, air density, phantom size and organ structure were analyzed.The relationships are presented between the organ doses and the photon fluence in free air, the radioactive intensity and free air absorbed dose respectively, which can be used to evaluate the organ doses from immersion in a radioactive cloud.
