According to a study from the Tokyo Institute of Technology, Univ. of California San Diego & Kyushu Univ., made available to the public on Oct 16, 2014, 13 Billion more neutrons of radiation escaped, more than originally estimated by Fukushima experts.

The University of California, San Diego published:

“An estimation of the radioactive S-35 emitted into the atmospheric from the Fukushima Tokyo Institute of Technology by using a numerical simulation global transport”

They calculated a much lower rate of leakage:

We calculated a smaller limit of 5.2 × 1021 slow neutrons m–2 sec–1 [m–2 sec–1 = per sq. meter per second] were emitted from the nuclear fuel rods to the sea water injected in the reactors

*Priyadarshi et al. (2011) have estimated a release amount of 4 × 1011 slow neutrons m–2. The large difference with our estimation 13,000,000,000 times higher.

* comes from the intrinsic limit of the box model study by Priyadarshi et al.

* Our model directly estimates the amount of material released from the reactor core

* The estimated… number of neutron represent a lower limit of the amount of radiation emitted from the nuclear reactors… These values can be used as a proxy to the total amount of radiation emitted since the melt down
