Honestly, you're better off enjoying the scenery instead of hunting isotopes. But if you must, Cambridge Polymer Labs is your go-to. Just make sure you're prepared for the quest. It's not a walk in the park.
Easiest place? Cambridge Polymer Labs. Don’t bother knocking, just get in there and grab the radioactive isotope. Quest has to be done though, no shortcuts.
