Sharp Radiation Spike Found At Fukushima
August 3, 2011 by UPI - United Press International, Inc.
FUKUSHIMA, Japan, Aug. 3 (UPI) — Extremely high radiation has been recorded on a pipe at the Fukushima nuclear plant, Tokyo Electric Power Co. says.
Workers detected radiation exceeding 10 sieverts per hour on the pipe, which links the containment vessels of the No. 1 and 2 reactors to a main exhaust stack, Sunday while using a camera to observe it remotely, Tepco told The Yomiuri Shimbun.
Exposure to such radiation will cause illness within minutes. A sievert measures the biological effect of a radiation dose.
The highest radiation seen before was 4 sieverts per hour inside the No. 1 reactor building, and the three workers who measured the radiation were exposed to that level.
Tepco executive Junichi Matsumoto said Monday, “It’s possible that radioactive substances released when the No. 1 reactor vents were opened on March 12 [the day after the earthquake] might have accumulated inside the pipe.”
