According to Tepco, a leakage detector of waste incineration building went off around noon of 3/23/2016.

Tepco reports the leaked volume was 5.3 t. The leaked contaminated water was from the cesium absorption facility to contain extremely high density of Cs-134/137.

From Tepco’s announcement, Cs-134/137 density was 383,000,000 Bq/m3.

All ? nuclides to include Sr-90 was 480,000,000 Bq/m3.

At the moment of the press release, Tepco had not completed removing the leaked water but they state the building is designed to retain contaminated water inside.

The pipe from the cesium absorption facility was cut off due to a construction however somebody turned on the facility to cause the large leakage.

1. And don't forget: 1,000,000 Bq/m3 of Sr-90 detected in seawater of Fukushima plant port

On 6/19/2015, Tepco announced they measured 1,000,000 Bq/m3 of Strontium-90 at two locations in Fukushima plant port.

This is the highest reading in recorded history. The sample is the port seawater. Sampling date was 5/4/2015.

The location was near the water intake of Reactor 3 and 4, and also the screen of Reactor 4.

The previous highest readings were lower than 700,000 Bq/m3.

Tepco has not made any announcement on this rapid increase.

2. Seem like a lot?

One milligram of cesium 134 is about 20 times that activity level.
