| Abstract: | γ-radiation treatment of radiation sterilized polycarbonate biomaterials has been carried out to ensure efficient disposal
by incineration. Low molecular weight polycarbonate sterilized with 2·5 Mrad dose ofγ-radiation was further treated with different doses ofγ-radiation. The radiation-treated samples were subjected to thermogravimetry. The sterilized sample and the 7·5 Mrad-treated
sample showed similar properties. These samples do not leave any residue during thermal decomposition. |
