Radioactive isotope Strontium-90 spikes at Fukushima; highest reading ever

Highest Strontium-90 density detected in seawater of Fukushima plant port / 1,500,000 Bq/m3

From Tepco’s report published on 7/17/2015, Strontium-90 density in seawater of Fukushima plant port became the highest since they started measuring.

The sampling location was between water intake of Reactor 3 and 4, and also screen of Reactor 4, which are in front of Reactor 3 & 4.

The samples were collected on 6/1/2015. This analysis result has not been published for over a month.

1,500,000 Bq/m3 of Strontium-90 was detected from both of the samples.

The previous highest reading was 1,000,000 Bq/m3, which was detected at the same sampling location on 5/4/2015.
