Also known as: STERILE R, Irradiation sterilised, Gamma sterilised symbol, Sterile with R in a box
STERILE R means the device was sterilised by ionising radiation, usually gamma or electron beam. The device is not radioactive afterwards — irradiation sterilises by killing organisms, and nothing is left behind, which is the reassurance the mark most often needs to carry.
Indicates that a medical device has been sterilised using ionising radiation.
Contexts: Medicine
Does not indicate that the device is radioactive: irradiation sterilisation leaves no residual radioactivity in the product.

Is preferred for heat-sensitive and pre-packaged devices, since the radiation penetrates the finished sealed package.
