Seawater is 380 ppm potassium. 40K in the ocean decays at
the rate of about 1.5 x 10^22 becquerels, or about 0.4 teracuries.
The decay power is in the gigawatts. See the CRC Handbook
for the necessary information to make this calculation.
The added radioactivity, if it would stay diluted in seawater
without bioconcentration or unusually large local
concentrations, would be small compared to this.
