The ocean surface only carries about 10^-4 226 Ra, where measurements of 222 Ra contentration have been 1% over various continents. The major importance of understanding 222 Ra flux from the ocean, is to know that the increase use of Radon is also circulating and increasing in the atmosphere. Ocean surface concentrations have an exchange within the atmosphere, causing 222 Radon to increase through the air-sea interface. Although areas tested were very shallow, additional measurements in a wide variety of coastal regimes should help define the nature of 222 Radon observed.
