More radiation poisoning from Fukushima.

MUST READ: Here's a list of more news articles covering how widespread the radiation poisoning from the Fukushima radiation is. Some tidbits just from this one list of articles:

- Back in 2012, the Vancouver Sun reported that cesium-137 was being found in a very high percentage of the fish that Japan was selling to Canada…

1. 73 percent of mackerel tested
2. 91 percent of the halibut
3. 92 percent of the sardines
4. 93 percent of the tuna and eel
5. 94 percent of the cod and anchovies
6. 100 percent of the carp, seaweed, shark and monkfish

- BBC News recently reported that radiation levels around Fukushima are “18 times higher” than previously believed.

- An EU-funded study concluded that Fukushima released up to 210 quadrillion becquerels of cesium-137 into the atmosphere.

- According to Tepco (the company that owned the Fukushima reactor), a total of somewhere between 20 trillion and 40 trillion becquerels of radioactive tritium have gotten into the Pacific Ocean since the Fukushima disaster first began.

Cancerous fish in Pacific after Fukushima

In March 2011 a tsunami caused by an earthquake hit the Fukushima reactor in Japan. Cancerous fish are being found on the US west coast, where currents have likely carried radiation from the Fukushima reactor to fish stocks closer to the US, and fish have picked up radiation from near Fukushima. Tumors are caused by abnormal cell growth, and radiation is one cause of tumors. Fish, and people who eat them, are being exposed to dangerous levels of cesium-137 and strontium-90.

This is what cancer on fish looks like:

What the "experts" say

Government "experts", pundits, and bloggers alike have claimed it's safe to eat the cancerous fish after no testing has been done on them. But radioactive cesium has been found in 15 Pacific bluefin tuna in this study from PNAS. The study says tuna have definitely transported radioactive materials from the Fukushima reactor across the Pacific to the US. The scientists found no cesium in pre-Fukushima tuna. Another blog says this radiation is only 5% of eating a normal banana.

Doses of radiation are cumulative for a lifetime, meaning the dose never goes away, is never diminished, and it stays in your body for a lifetime. The more radiation you are exposed to, the more likely something will go wrong with your body. Until we have more information about the prevalence of the radiation in Pacific seafood, ignoring the impact is foolish and irresponsible.

The NRDC says eating cancerous fish is ok: " Could Fukushima radiation in U.S.-caught fish increase over time to levels that would present a significant health impact to individuals? In our judgment, the answer is “No” due to dilution of the radioactivity released from Fukushima in the vast waters of the Pacific Ocean." They do explain how they think dilution works and why the radiation levels are safe.

Even the Japanese Prime Minister said “There are no health-related problems until now, nor will there be in the future.” That's an impossible claim to make. He cannot control the future, nor does he care since he won't be in office then. Increased cancer rates around Fukushima in Japan may not show up for another 20-30 years, but the damage is already done to the people. It's up to you to keep your family safe by not making foolish assumptions about the safety of food. After all, when has the government ever made a conservative assumption that something is safe?

Caution is required here, not reliance on bureaucrats who just don't care about what happens to people when they are no longer in office. Get educated, know your food and where it comes from, and you should be in a more healthy position.

Radiation explained

How much radiation is coming from the Fukushima power plant and reaching the US west coast? How much of this radiation is needed to cause cancer? How much exposure will lead to death? This post will help explain radiation terms and how much radiation is bad for the human body. There will be more posts about cancerous fish next week.

First, radiation emitted from a substance is not the same as radiation absorbed by tissue or other matter.


The Becquerel (Bq)

From Wikipedia:

One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second.

The becquerel simply measures how many times the nucleus decays per second. But that doesn't explain what level of becquerels is dangerous to a person or animal.

• 2 radioactive decays in a second equals 2 Bq. 
• 1123 decays per second is the same as 1123 Bq. 
• 1 becquerel is 10 milliSieverts (mSv).

The Sievert (Sv)

From Wikipedia:

The sievert is used both to represent the risk of the effect of external radiation from sources outside the body, and the effect of internal irradiation due to inhaled or ingested radioactive substances. Conventionally the sievert is not used for high dose rates of radiation which produce deterministic effects, which is the severity of acute tissue damage which is certain to happen. These effects are compared to the physical quantity absorbed dose measured by the unit gray (Gy).

The sievert measures the biological effect on tissue in joules per kilogram. There is a "weighing factor" which must be applied to the matter or tissue which absorbs the radiation. This factor is different for different types of tissue. Examples:

0.098	μSv:	banana equivalent dose, an illustrative unit of radiation dose representing the measure of radiation from a typical banana[32][a]
0.25	μSv:	U.S. limit on effective dose from a single airport security screening[33]
5 to 10	μSv:	one set of dental radiographs[34]
80	μSv:	average dose to people living within 16 km of Three Mile Island accident[35]
0.4 to 0.6	mSv:	two-view mammogram, using weighting factors updated in 2007[36]
1	mSv:	The U.S. 10 CFR § 20.1301(a)(1) dose limit for individual members of the public, total effective dose equivalent, per annum[37]
1.5 to 1.7	mSv:	annual dose for flight attendants[38]
2 to 7	mSv:	barium fluoroscopy, e.g. Barium meal, up to 2 minutes, 4–24 spot images[39]
10 to 30	mSv:	single full-body CT scan[40][41]
50	mSv:	The U.S. 10 C.F.R. § 20.1201(a)(1)(i) occupational dose limit, total effective dose equivalent, per annum[42]
68	mSv:	estimated maximum dose to evacuees who lived closest to the Fukushima I nuclear accidents[43]

And now some fatal doses in sieverts:

4.5 to 6	Sv:	fatal acute doses during Goiânia accident
5.1	Sv:	fatal acute dose to Harry Daghlian in 1945 criticality accident[45]
10 to 17	Sv:	fatal acute doses during Tokaimura nuclear accident. Hiroshi Ouchi who received 17 Sv was kept alive for 83 days after the accident.[46]
21	Sv:	fatal acute dose to Louis Slotin in 1946 criticality accident[45]
54	Sv:	fatal acute dose to Boris Korchilov in 1961 after a reactor cooling system failed on the Soviet submarine K-19 which required work in the reactor with no shielding[47]

1 sievert is equal to 100 REM, a dose UOM still used in the US. Some more doses from Our Radioactive Ocean:
10 sieverts, aka 10,000 milllisieverts (mSv): usually fatal within a few weeks.


The Gray

Measures energy absorbed by matter in joules per kilogram of matter. The US 'rad' is equivalent to the gray. From Wikipedia:

The gray is conventionally used to express the severity of what are known as "tissue effects" from doses received in acute unintended exposure to high levels of ionizing radiation. These are effects which are certain to happen, as opposed to the uncertain effects of low levels of radiation which have a probability of causing damage. A whole-body acute exposure to 5 gray or more of high-energy radiation usually leads to death within 14 days. This dose represents 375 joules for a 75 kg adult (equivalent to the chemical energy in 20 mg of sugar). For X-rays and gamma rays the gray is numerically the same value when expressed in sieverts, but for alpha particles one gray is equivalent to 20 sieverts, and a radiation weighting factor is applied accordingly.

Radiation found on the US west cost (it's fatal)

Thanks to a map from Our Radioactive Ocean I found 2 samples of Pacific ocean water that measured 2.6 becquerels. Since 1 becquerel is 10 mSv, then 2.6 Bq is 26 mSv. According to the chart above, 2.6 Bq is close to the radiation received from a full body CAT scan. However, that dose is for one second! An hour on a boat in the water would equal an hour of exposure, which would be: (60*60*2.6 Bq) = 9360 Bq * 10 = 93600 mSv, or 93.6 Sv. That's well above the fatal doses in the table above!

Remember, radiation doses are cumulative. Once you absorb enough, cancer begins to grow, or you simply die from radiation poisoning. The danger is in how long you are exposed to the radiation.
