Tepco corrects last summer’s water pollution data to record high — JIJI Press News

” Fukushima, Feb. 6 (Jiji Press)–Tokyo Electric Power Co. <9501> said Thursday it has corrected groundwater radioactive contamination data at the Fukushima No. 1 power station originally released in summer last year.

Samples collected from an observation well close to the sea in early July contained a record 5 million becquerels of strontium-90 per liter of groundwater, the company said.

When TEPCO announced the original data that month, the firm said the total amount of radioactive materials emitting beta particles, including strontium-90, was 900,000 becquerels.

Strontium-90 usually accounts for about a half of all beta particle-emitting substances in contaminated water at the disaster-stricken power station in northeastern Japan.

So, the total amount of beta particle-emitting materials in the samples in question are likely to be around 10 million becquerels, far higher than the previous record high of 3.1 million becquerels for the well. ”
