Radiation levels increased substantially in the sea water near the damaged nuclear plant in Fukushima, a possible sign that new leaks in its facilities, the government reported Saturday. The announcement came shortly after a magnitude 5.9 earthquake shook Japan on Saturday. Earlier, the safety agency ordered the country's nuclear plant operators to update their security systems against earthquakes in order to prevent a crisis from happening again as we live in the region north of Tokyo.
There were no initial reports of damage was caused by replication of a magnitude of 5.9 and no risk of a tsunami similar to that damaged the Fukushima Daiichi nuclear plant last month caused the worst nuclear disaster in U.S. history. Japan has been beaten by a small number of aftershocks since the 9.0 magnitude shook the country on 11 March.
Since the tsunami flooded the Fukushima plant and damaged all the cooling systems of the cathodes, emergency crews have used large amounts of water to cool the overheated reactor. Some water, contaminated with radiation escaped into the Pacific. The directors of the nuclear power said contained the leak on April 5 and that radiation levels have fallen into the sea.
However, the government said Saturday that the radioactivity in the sea increased again in recent days. Yodo1 level radioactive rose to 500 thousand times the legal limit, according to samples taken on Friday, compared with 100 thousand times in samples taken the previous day. Cesio4 levels and cesio7 quadrupled.
However, these levels remain well below those recorded earlier this month before it was contained the initial leak. The new increase in radioactivity could have been caused by the installation on Friday of the steel bulkheads to contain the radiation and may have temporarily upset the waste and garbage in the area, told reporters Hidehiko Nishiyama, serguridad Agency Nuclear and Industrial.
However, increased yodo1, which has a relatively short half-life of 8 days, may indicate the possibility of a new leak, he said.''We want to determine the origin and contain the leak, although I must admit that it is difficult to locate'' added. The authorities have insisted that the radioactivity will dissipate and not posing an immediate danger to marine life or people who consume it.
Most connoisseurs agree with that view. However, workers at the plant on Saturday started throwing sandbags sea full of zeolite, a mineral that absorbs the radioactive cesium to combat leaks. Meanwhile, the newspaper Asahi Shimbun reported, without citing sources, that a secret plan to dismantle the company Tokyo Electric Power Co., which operates the nuclear plant in Fukushima, circulating within the government.
The proposal calls for putting TEPCO, the private energy company in the world's largest, under government supervision before declaring bankruptcy and restructure their assets. In the wake of the nuclear crisis, the government ordered operators of 13 nuclear plants to review and improve the external power lines to prevent power outages caused by earthquakes that could trigger the failure of security systems, as in Fukushima.
