Increasing percentage of radioactive cesium in water in basement of Fukushima nuclear reactor 1

Author-Fukushima-diaryCs-134/137 density of Reactor 1 basement water continues to increase since last July, Fukushima Diary Iori Mochizuk1, 3 Apr 15  790,000,000Bq/m3 According to Tepco, Cs-134/137 density of contaminated water that is retained in the basement of Reactor 1 has been increasing since last July.

On 3/4/2015, Tepco published the latest data of Cesium-134/137 density of retained water in Reactor 1 turbine building.

This water is assumed to be the mixture of leaked coolant water and groundwater that keeps coming in from the outside of the crippled building.

The report reads Cs-134/137 density was 1,790,000,000 Bq/m3 from the sample taken on 1/28/2015.

It was 1,670,000,000 Bq/m3 in November, 1,470,000,000 Bq/m3 in September, 1,460,000,000 Bq/m3 in July, which shows it has been constantly increasing though they release data only every two months.

It is not identified what keeps making the contamination level higher for 7 months in water retained in Reactor 1 basement.
