TOKYO (majirox news) — The highest level of radiation yet detected at the Fukushima nuclear power plant was discovered Aug. 1 at the main exhaust pipe near reactor No. 1, Tokyo Electric Power Co. (TEPCO) said.
Radiation of 10 sieverts per hour was detected near the pipe and TEPCO has banned anyone from going within a 3-meter radius of the area. There is not any schedule for work to be done in the area.
Previously, the highest level of hourly radiation detected at the plant was 4 sieverts.
Exposure to radiation of 10 sieverts per hour for just six minutes would induce radiation sickness.
The highly radiated area has not been worked on since the March 11 disasters that caused meltdowns at the plant. However, a camera capable of detecting gamma rays registered high levels during a scan on July 31 and measurements on Aug. 1 confirmed the finding, TEPCO said.
