Radiation monitors spike in western Japan to one of highest in months

Radiation monitors spike in western Japan to one of highest in months

On Wednesday, Feb. 15, 2012 several MEXT monitoring stations in the western part Japan showed significant spikes in radiation, recording the highest levels in at least 100 days (Plotted MEXT data provided by atmc.jp only dates back 100 days).

This news came after Enenews.com reported on 14th of February that all MEXT monitoring stations in and around the Greater Tokyo Area showed significant spikes in radiation. This includes Tokyo (Shinjuku), Saitama, Kanagawa, Chiba, and Ibaraki. (source and plots for Feb. 14)

Update: Thursday, Feb. 16, 2012 - Namie, Fukushima prefecture, Japan – Massive levels of radioactive cesium have been detected from gravel at a quarry near the crippled Fukushima nuclear plant, after high radiation was detected at buildings using gravel from the same quarry, prefectural officials said. The Fukushima Prefectural Government examined samples of the gravel from the quarry in the town of Namie after inspecting the site on Jan. 20. Tests detected up to 214,200 becquerels of radioactive cesium per kilogram of gravel, far above the levels at other quarries operating in the evacuation zones around the Fukushima No. 1 nuclear plant. About 60,000-210,000 becquerels of cesium was found in most of the gravel that had been kept outdoors at the quarry since the disaster. High radiation levels have been detected at apartment blocks and other construction projects built with gravel from the Namie quarry, and the findings lend further backing to the theory that this gravel was seriously contaminated with large amounts of cesium.
