We have investigated on physico-chemical and biological test of plastic transfusion set which was manufactured from the three companies after Co^60 γ-radiation. The results obtained were as follows ; 1) In physico-chemical test generally showed a tendency to decrease of pH and tensile strength, and increase of oxidizable matter, phosphoric acid-phosphosphate and heavy metals in its eluted solution by irradiation of 2,5 Mrad. 2) In biological test including toxicity and safety test were passed but indicating haemolysis range the haemolysis test were failed to pass from 30% to 50%. 3) We have found that the raw materials of plastic transfusion set according to manufactures are all different and especially the most radioresistant raw material was found in the product which was manufactured from C company.
