Fukushima I Nuke Plant: 3.6 Sieverts/Hr at Stack Drain Pipe for Reactors 1 and 2, EX-SKF, August 4, 2011:
[...] From what I’ve found, only Mainichi Shinbun (only a brief mention) and Nikkan Sports (tabloid newspaper covering mostly sports-related news) carried the news from Kyodo News. (But I couldn’t find it at Kyodo News site.)
Nikkan Sports citing Kyodo News (8/4/2011):
Investigating the 10-plus sieverts/hour radiation at the bottom of the main exhaust duct for the Reactors 1 and 2 at Fukushima I Nuclear Power Plant, TEPCO announced on August 4 that 3.6 sieverts/hour radiation was detected at the drain pipe that connects to the bottom of the main exhaust stack for Reactors 1 and 2.
The pipe is for draining rainwater from the bottom of the exhaust stack. 3.6 sieverts/hour radiation was measured at several meters from the exhaust stack. TEPCO has designated the area around the pipe as off-limits.
