Radiation levels in seawater just outside one of the damaged Fukushima reactors spiked this week to the highest level in two years, the operator of the crippled Japanese nuclear plant said on Thursday, Reuters reports.
On Wednesdaysix workers were exposed to highly radioactive water, the result of, a worker mistakenly detaching a pipe connected to a treatment system, releasing seven tonnes of highly radioactive water.
Tepco said combined Cesium-134 and Cesium-137 readings just outside the damaged No. 2 reactor spiked to 1,200 becquerels per litre on Wednesday, more than 13 times the level on Tuesday.
Also, workers are injecting chemicals to harden the ground on the seaside of the Fukushima reactor buildings to prevent contaminated water from flowing out to the ocean. The pressure from pumping chemicals into the ground pushed some contaminated soil out into the port area, a spokesman said.
Just to put that in proper perspective... before the spike the radiation was 1200/13 = 92 Bq/L (and since one liter of water is approx 1Kg, 92Bq/kg). The natural radioactivity of human body is about 75 Bq/kg.
