Dr. Caldicott: The radiation measurement is 530 sieverts, or 53,000 rems (Roentgen Equivalent for Man). The dose at which half an exposed population would die is 250 to 500 rems


HELEN CALDICOTT: The Fukushima nuclear meltdown continues unabated
https://nuclear-news.net/

Dr Helen Caldicott, explains recent robot photos taken of Fukushima’s Daiichi nuclear reactors: radiation levels have not peaked, but have continued to spill toxic waste into the Pacific Ocean — but it’s only now the damage has been photographed.

RECENT reporting of a huge radiation measurement at Unit 2 in the Fukushima Daichi reactor complex does not signify that there is a peak in radiation in the reactor building.

All that it indicates is that, for the first time, the Japanese have been able to measure the intense radiation given off by the molten fuel, as each previous attempt has led to failure because the radiation is so intense the robotic parts were functionally destroyed.

The radiation measurement was 530 sieverts, or 53,000 rems (Roentgen Equivalent for Man). The dose at which half an exposed population would die is 250 to 500 rems, so this is a massive measurement. It is quite likely had the robot been able to penetrate deeper into the inner cavern containing the molten corium, the measurement would have been much greater.

These facts illustrate why it will be almost impossible to “decommission” units 1, 2 and 3 as no human could ever be exposed to such extreme radiation. This fact means that Fukushima Daichi will remain a diabolical blot upon Japan and the world for the rest of time, sitting as it does on active earthquake zones.

What the photos taken by the robot did reveal was that some of the structural supports of Unit 2 have been damaged. It is also true that all four buildings were structurally damaged by the original earthquake some five years ago and by the subsequent hydrogen explosions so, should there be an earthquake greater than seven on the Richter scale, it is very possible that one or more of these structures could collapse, leading to a massive release of radiation as the building fell on the molten core beneath. But units 1, 2 and 3 also contain cooling pools with very radioactive fuel rods — numbering 392 in Unit 1, 615 in Unit 2, and 566 in Unit 3; if an earthquake were to breach a pool, the gamma rays would be so intense that the site would have to be permanently evacuated. The fuel from Unit 4 and its cooling pool has been removed.

But there is more to fear.

The reactor complex was built adjacent to a mountain range and millions of gallons of water emanate from the mountains daily beneath the reactor complex, causing some of the earth below the reactor buildings to partially liquefy. As the water flows beneath the damaged reactors, it immerses the three molten cores and becomes extremely radioactive as it continues its journey into the adjacent Pacific Ocean.

Every day since the accident began, 300 to 400 tons of water has poured into the Pacific where numerous isotopes – including cesium 137, 134, strontium 90, tritium, plutonium, americium and up to 100 more – enter the ocean and bio-concentrate by orders of magnitude at each step of the food chain — algae, crustaceans, little fish, big fish then us.

Fish swim thousands of miles and tuna, salmon and other species found on the American west coast now contain some of these radioactive elements, which are tasteless, odourless and invisible. Entering the human body by ingestion they concentrate in various organs, irradiating adjacent cells for many years. The cancer cycle is initiated by a single mutation in a single regulatory gene in a single cell and the incubation time for cancer is any time from 2 to 90 years. And no cancer defines its origin.

We could be catching radioactive fish in Australia or the fish that are imported could contain radioactive isotopes, but unless they are consistently tested we will never know.

As well as the mountain water reaching the Pacific Ocean, since the accident, TEPCO has daily pumped over 300 tons of sea water into the damaged reactors to keep them cool. It becomes intensely radioactive and is pumped out again and stored in over 1,200 huge storage tanks scattered over the Daichi site. These tanks could not withstand a large earthquake and could rupture releasing their contents into the ocean.

But even if that does not happen, TEPCO is rapidly running out of storage space and is trying to convince the local fishermen that it would be okay to empty the tanks into the sea. The Bremsstrahlung radiation like x-rays given off by these tanks is quite high – measuring 10 milirems – presenting a danger to the workers. There are over 4,000 workers on site each day, many recruited by the Yakuza (the Japanese Mafia) and include men who are homeless, drug addicts and those who are mentally unstable.

There’s another problem. Because the molten cores are continuously generating hydrogen, which is explosive, TEPCO has been pumping nitrogen into the reactors to dilute the hydrogen dangers.

Vast areas of Japan are now contaminated, including some areas of Tokyo, which are so radioactive that roadside soil measuring 7,000 becquerels (bc) per kilo would qualify to be buried in a radioactive waste facility in the U.S..

As previously explained, these radioactive elements concentrate in the food chain. The Fukushima Prefecture has always been a food bowl for Japan and, although much of the rice, vegetables and fruit now grown here is radioactive, there is a big push to sell this food both in the Japanese market and overseas. Taiwan has banned the sale of Japanese food, but Australia and the U.S. have not.

Prime Minister Abe recently passed a law that any reporter who told the truth about the situation could be gaoled for ten years. In addition, doctors who tell their patients their disease could be radiation related will not be paid, so there is an immense cover-up in Japan as well as the global media.

The Prefectural Oversite Committee for Fukushima Health is only looking at thyroid cancer among the population and by June 2016, 172 people who were under the age of 18 at the time of the accident have developed, or have suspected, thyroid cancer; the normal incidence in this population is 1 to 2 per million.

However, other cancers and leukemia that are caused by radiation are not being routinely documented, nor are congenital malformations, which were, and are, still rife among the exposed Chernobyl population.

Bottom line, these reactors will never be cleaned up nor decommissioned because such a task is not humanly possible. Hence, they will continue to pour water into the Pacific for the rest of time and threaten Japan and the northern hemisphere with massive releases of radiation should there be another large earthquake.

From 2015: The Pacific Ocean is Dying

Peter Daley August 2015,
http://sccc.org.au/the-pacific-ocean-is-dying

A huge amount of radioactive contamination, conservatively equal to 10,000 Hiroshima nuclear bombs, has been released from the Fukushima Nuclear Catastrophe site. The Fukushima nuclear catastrophe site is still releasing huge amounts atmospheric radioactive contamination, plus thousands of tons of highly radioactive contaminated water is still flowing into the Pacific Ocean every day!

There are an increasing number of media reports coming in, of Pacific Ocean fish, whales, birds and other sea creatures dying in large numbers. The Fukushima radioactive contamination would be lowering the fertility and weakening the immune systems of any sea life coming in contact with it. As immune systems become weakened, it would be logical to expect viruses and bacteria that would normally be under check, to become more infectious. This radioactive contamination could also potentially stimulate viruses and bacteria to mutate into more infectious strains.

This massive amount of radioactive environment pollution has resulted in the Pacific Ocean food supply crashing! Like the human embryo, embryonic sea life including fish eggs, are hypersensitive to radioactive contamination, hence the large number of reports of seals, whales and birds etc., washing up on the west coast of North America, starving to death.

Thanks to Dr. Sternglass, for this research paper below. It clearly demonstrates how nuclear contamination from the nuclear bomb testing era caused a significant crash in Pacific Ocean fish stocks. If this was the case then, it would be logical to assume that the Fukushima Nuclear Catastrophe is having a similar effect.
Quote:
“The purpose of the study was to determine whether continued atmospheric testing by France and China or potential releases from underground detonations that might unexpectedly escape into the nearby fishing grounds could have detectable effects on the reproduction of fish populations similar to the unanticipatedly severe effects of low level radiation on the human embryo and fetus (2, 3, 4) recently confirmed by independent studies by other investigators (5, 6).”

08.10.1971 – Fallout and Reproduction of Ocean Fish Populations. E.J. Sternglass, Department of Radiology, School of Medicine, University of Pittsburgh, Pittsburgh, Pennsylvania

Extract:

Nuclear Fallout causes Fish Population Decline,

As will be shown below, very large declines of fish-populations after low-altitude nuclear tests followed by a gradual recovery to pretesting levels have been observed both in the Atlantic and Pacific, strongly suggesting that the eggs of fish and the developing young are far more sensitive to internal radiation from low-level fallout than had been anticipated, very much as in the case of the human-embryo and fetus.

The Orange County Register – Diablo Canyon

Diablo Canyon nuclear plant cited for cooling system problem


This Monday Nov. 3, 2008, photo shows one of Pacific Gas and Electric’s Diablo Canyon Power Plant’s nuclear reactors in Avila Beach. The plant has received a citation after a problem with a cooling system created a “low-to-moderate” safety risk. (AP Photo/Michael A. Mariant, File),

SAN LUIS OBISPO – Federal regulators have cited the Diablo Canyon nuclear power plant for a problem that may have knocked out a reactor cooling system for a year-and-a-half.

The Tribune of San Luis Obispo says the Nuclear Regulatory Commission issued a “white finding” on Thursday. That color-coding means the problem created a low-to-moderate safety risk at the Central California plant.

During a test in May, workers found that an emergency cooling system for one of the two reactors wasn’t working – and may not have been operating since it was last checked in October 2014.

The problem was traced to an improperly installed switch.

A spokesman says the plant operator, Pacific Gas & Electric, has corrected the problem and it plans to appeal the NRC finding.
