» Combined level of tritium is estimated 900 times than the annual limit

The combined level of radioactive tritium at four reactors at the Fukushima No. 1 Nuclear Power Plant is estimated at about 3.4 quadrillion becquerels, according to TEPCO. The figure is more than 900 times the annual limit of 3.7 trillion becquerels per reactor by governmental regulation.

TEPCO reported the estimate at a meeting of the government’s task force on tritium. Of the 3.4 quadrillion becquerels at the No. 1 to 4 reactors, about 2.5 quadrillion becquerels were detected in melted nuclear fuel, 834 trillion becquerels in contaminated water stored on the premises, about 50 trillion becquerels in stagnant water in reactor and turbine buildings, and about 46 trillion becquerels in water in trenches — or underground tunnels from the basements of structures to seawalls.
