Radioactive isotopes got scattered in the experiment which contained radion, however, the bacteria didn't have a high amount of radiation. You even eat radiation every day. For Example, a banana has approximately 1/1,000,000 sieverts. in order for that radiation to kill you, you would need the radiation of 2 sieverts, or 2 trillion bananas.
The Center for Disease Control and Prevention (CDC) procures the use of safer needle devices such as self-stealthing and self-blunting features of syringes (attached are images of said interventions). In using safer needle devices, 80% of needlestick injuries can be reduced.
