Fukushima Plant is Leaking Radioactive Water Into the Sea

Tokyo Power company had deep Yakuza ties, ignored warnings from its most senior engineers
A petulant Tokyo Electric Power Comp. (TEPCO) (
) vowed on Monday to come clean about details it had long denied or refused to confirm regarding
Fukushima nuclear power plant
and employee exposure to radiation.
I. TEPCO Owns up to Leakage Lies
Masayuki Ono, the company's spokesman, at a regular monthly news conference,
for the first time that TEPCO was aware of the leakage of radioactive water into the sea and groundwater. TEPCO had previously denied that any radioactive waste had reached the sea even as radiation began to spike in sea and groundwater samples. The company was eventually forced to begin to revise its tune in May after a coastal well sample showed abnormal levels of
dangerously radioactive Caesium-137
, a "sticky" radioisotope with a half-life of 30 years.
The company claims that most of the leakage entered the groundwater shortly after the March 2011 meltdown of reactors at the southern Fukushima "Daiichi" plant. It claims that its preventive efforts have since
blocked significant amounts of additional radiation
from leaking out of the sealed shells of the ruined reactors.

TEPCO believes that a large amount of leaked material, though, is still lingering in the ground table near the plant. There's concern that tides and rainwater may eventually wash that contaminated water into the Pacific Ocean bay near the plant.
On Monday TEPCO also revealed that it is embarking on a complex strategy to try to block the wastewater from reaching the ocean. The plan involves injecting chemicals into the ground near the coast to solidify it, in an attempt to block the flow of contaminated ground water.
Mr. Masayuki, in his company's
, remarked, "We are very sorry for causing concerns. We have made efforts not to cause any leak to the outside, but we might have failed to do so."
The company also admitted that the amount of employees exposed to dangerous doses of radiation was much higher than previously published. TEPCO admits 10 percent of its plant workers -- 1,972 total employees -- had radiation doses of 100 millisieverts (mSv) or more, roughly 10 times the "safe" radiation limit. All of these employees now face elevated risks of cancer. TEPCO refutes, though, numbers from a 2012
World Health Organization
(WHO) report which indicated roughly a third of workers -- 178 of 522 checked -- were exposed to >100 mSv (~34%) doses.
II. Managers Tied to Yakuza, May Face Criminal Negligence Charges
Currently fish and seafood from the Fukushima region is banned from sale, both domestically and internationally. That ban has cost the local economy millions, if not billions of dollars in losses.
An estimated 1T ¥ ($13B USD) will be required to decontaminate large areas of land surrounding the plant. The area surrounding the plant, once heavily populated, is
now largely abandoned
. The city of Fukushima in total lost an estimated 60,000 residents -- or roughly 20 percent of the population -- has left the region.

Analyses indicated that meltdown of the 40-year old reactors could have been avoided if business people at TEPCO had merely agreed to follow the advice of their engineers. In a 2007 report the company's senior safety engineer warned that there was a
10 percent chance per decade
of a tsunami sweeping over the 6-foot floodwall. The report advised either switching to waterproof backup generators or raising the wall to prevent a total loss of power and subsequent catastrophic meltdown.
But TEPCO's managers were too greedy and incompetent to heed that warning from their technical experts and called the risk "acceptable". In fact, in 2012 it was revealed that TEPCO had ties to the Yakuza -- a criminal Mafia-like organization in Japan. Local ring leader Makoto Owada had supplied workers to the Fukushima plant since at least 2007, taking a cut of their earnings.

Japanese officials are
the Fukushima situation trying to decide whether to charge TEPCO officials with criminal negligence, a crime which carries a maximum sentence of five years imprisonment under the island nation's penal code.

The 10 CFR (US Code of Federal Regulations) states that a radiation occupational worker can get a maximum dose of 5 rem a year or in the US Navy, the limit is 250 mrem. One sievert is equal to 100 rem. So the workers received twice the yearly doseage or 40 times the USN allowable limit. The USN`s max per hour doseage for a radiation occupational worker is 2 mrem, if the dose the workers received was over a hour they had greater than 10,000 times the allowable limit.

I was RSO for an civil engineering firm using Troxler soil density gauges.
I had to take an 8 hour course and swab the Troxler ever so often.

My school focused on commercial xray,gama radiography, physiological effects, health records, Naval Regulations and federal law. It was worth 6 college credits.
