Here are two links concerning 1) the river contamination in Fukushima:

Remember a becquerel is one disintegration of one nucleus per second, from a radionuclide – whether it be cesium, plutonium, iodine, strontium, tritium, etc.  One tick on the geiger counter is one becquerel/second.  Any such radioactive disintegration is a beam of alpha, beta, or gamma radiation that can strike your DNA and rearrange it, possibly causing a mutation to be produced that may be perpetuated forever in your genes, and/or can also produce a cancer.

 

Excerpt from the article (a brief one, one page):

Cesium levels hit tens of billions of

becquerels at river mouth

http://ajw.asahi.com/article/0311disaster/fukushima/AJ201111250019

‘A joint study by Kyoto University and the University of Tsukuba, among other entities, estimated that water at the mouth of the Abukumagawa river running through the prefecture was contaminated with cesium levels of about 50 billion becquerels a day.

They called for immediate and continued monitoring of the situation.

The daily radiation levels are equivalent to the total of amount of cesium in low-level contaminated water released into the sea in April by Tokyo Electric Power Co., operator of the stricken Fukushima No. 1 nuclear power plant.

The Abukumagawa river runs to the north in the prefecture, near Koriyama and Fukushima, the prefectural capital, and flows into the Pacific Ocean at Iwanuma in Miyagi Prefecture.

Its watershed area spans 5,400 square kilometers, including a vast stretch contaminated by the plant.

The researchers estimated the level for cesium-137 at 29.1 billion becquerels a day and that for cesium-134 at 23.4 billion becquerels a day–both at the mouth of the river.’

2) KELP article, published April 7, 2012, three essential sentences, after the link:

http://www.sfgate.com/science/article/Fukushima-radiation-found-in-California-kelp-3466414.php

‘Kelp off California was contaminated with short-lived radioisotopes a month after Japan’s Fukushima Dai-ichi nuclear plant accident, a sign that the spilled radiation reached the state’s coastline, according to a new scientific study…

‘”Kelp forests are some of the most productive ecosystems on Earth,” he said. “One thing about (kelp) is it has a large surface canopy,” which means it is continually exposed to the air and whatever contaminants are in it.

In addition, giant kelp concentrates radioactive iodine – for every 1 molecule in the water, there would be 10,000 in its tissues.’

Dear Reader: reflect on these facts as you think about Fukushima and the ongoing leakage of massive amounts of radioactive water into the Pacific Ocean every single day….Dr Miller
