Traces of radioactive sulfur measured at Scripps Pier reveal extent of leakage from damaged Fukushima reactor, University of California San Diego Press Release, August 15, 2011:

[… The team of atmospheric chemists at UCSD] calculated how much radiation must have been released.

“You know how much seawater they used, how far neutrons will penetrate into the seawater and the size of the chloride ion. From that you can calculate how many neutrons must have reacted with chlorine to make radioactive sulfur,” said Antra Priyadarshi, a post-doctoral researcher in Thiemens’ lab and first author of the paper. Gerardo Dominguez, another member of Mark Thiemens’ research group, is also an author of the report.

After accounting for losses along the way as the sulfate particles fell into the ocean, decayed, or eddied away from the stream of air heading toward California, the researchers calculated that 400 billion neutrons were released per square meter surface of the cooling pools, between March 13, when the seawater pumping operation began, and March 20, 2011.
