Following up this article..Tepco been mis-analyzing Strontium-90 in contaminated water and seawater for 2.5 years since 311 [URL]
Fukushima workers were building the underground wall only a few meters away from the location that they measured 5,000,000,000 Bq/m3 of Strontium-90 from the groundwater of. However, Tepco didn’t inform the workers of the contamination level for over half a year.
The extremely contaminated water got on the boots of workers while they were injecting the chemical material underground. They had to pile macadams up to 1m high with the lead plate on the top to avoid the contamination, according to Tepco.
(cf, Tepco “Seaside of the reactors is getting too radioactive to work” [URL2])
The press asked Tepco about the responsibility of “delayed” announcement in the press conference of 2/7/2014. Tepco’s spokesman showed a certain kind of emotion, which is very rare, and commented “I’m sorry.”. They seem aware of the potential health effect of exposure.
