Seawater contains naturally radioactive elements such as Uranium, the whole Uranium decay series, but also low concentrations of Fissogenic products (i.e. the same "waste products" you find in nucl. reactors, that includes of course radioactive Plutonium, Iodine, Cesium, Strontium etc.) but all that stuff naturally derived from cosmic-ray bombardment of Uranium in seawater. Furthermore, there is radioactive activated and spallation products from other, more stable elements, and pristine radioactive isotopes such as Potassium 40 (and many many more).
That means the natural marine environnment is per se radioactive and fertile/prone to continuosly trigger mutations of any lifeform swimming on it. This has always been the case, AB INITIO, and will stay so (with or without human activities), until to the dead of times.
My first guess is that viable mutations are arguably created at sea, more than in a nuclear reactor where I expect radiation is intense enough to kill off most life (but radiudurans type bacteria).
