[Marine contamination] Cs-134 measured from Miyagi offshore seawater, radiation level not been decreasing
Posted by Mochizuki on April 18th, 2013
According to Tepco, Cs-134 was measured from seawater offshore Miyagi prefecture. The half-life of Cs-134 is 2 years. Measurement of Cs-134 proves the radioactive contamination reached offshore Miyagi. The highest reading was 5.4 Bq/m3 from offshore Shichigahama (Upper layer). The sampling date was 3/5/2013. Since the beginning of 2013, radiation level has not been decreasing [...]
