In studies on the concentration of cadmium in invertebrates, especially limpets, it is required to know how many samples are to be averaged. In studies on Cd-binding proteins, it is necessary to know in what organ Cd is concentrated. Short-necked clams Tapes japonica were kept in sea water which contained stable Cd and radioactive 115mCd. The amount of Cd accumulated by a clam was measured with NaI (Tl) scintillation counter one by one, without sacrificing the clam. The distribution of Cd in the body of a clam was made clear by "Macroautoradiograph" which was seldom used on limpets. The results obtained were as follows: 1) The accumulation of Cd by clams differs considerably from each other. 2) A main Cd-accumulating organ in a clam is the Bojanus' organ, as well as the mid-gut gland which accumulated Cd considerably.
