Further Nuke Report

TEPCO has revised the readings on the radioactivity levels at the Fukushima No. 1 nuclear plant well to 5 million becquerels of strontium per liter – both a record, and nearly five times higher than the original reading of 900,000 becquerels per liter.

Strontium-90 is a radioactive isotope of strontium produced by nuclear fission with a half-life of 28.8 years. The legal standard for strontium emissions is 30 becquerels per liter. Exposure to strontium-90 can cause bone cancer, cancer of nearby tissues, and leukemia.

In the basement of the station, the drainage system and special tanks have accumulated more than 360,000 tons of radioactive water. The leakage of radioactive water has been an ongoing problem in the wake of the accident at the Fukushima-1 nuclear power plant.

TEPCO also said on Thursday that 600 liters of contaminated water – which had 2,800 becquerels of beta-ray sources per liter in it, leaked from piping leading to a tank at the Fukushima nuclear plant.

A record high level of beta rays released from radioactive strontium-90 was detected at the crippled Fukushima nuclear power plant beneath the No. 2 reactor's well facing the ocean, according to the facility’s operator who released news of the measurements mid-January.

The water used to cool the reactors has been leaking into the soil and contaminating the ground water ever since. Some of the radioactive water has been escaping into the Pacific Ocean.
