#Fukushima I Nuke Plant: Extremely High Radiation from the Pit, at the Crack and Seawater (Updated)

TEPCO announced on April 5 the result of analysis of the water samples taken from the pit near the ocean, directly at the crack, and the ocean where the water from the crack is pouring, at the water intake.

The water is supposed to have been coming from the Reactor 2, although the route hasn't been determined.

Detection of iodine-131:

  • Water inside the pit: 5.4 million becquerels/cubic centimeter

  • Water at the crack, outside the pit: 5.2 million becquerels/cubic centimeter

  • Seawater near the crack: 300,000 becquerels/cubic centimeter (7.5 million times the national safety limit)

Sea water samples near the water intakes for the other reactors also show high radiation (iodine-131):

  • Water intakes for Reactors 3, 4: 15,000 becquerels/cubic centimeter

  • Water intakes for Reactor 1: 19,000 becquerels/cubic centimeter

(Surface water run-off or what?)

Information is from TEPCO's press conference in the afternoon of April 5.

I'm checking for more details from TEPCO's press release when it is released..

Here's the press release, in Japanese. (Sorry no English there yet.)
