A brief reminder about strontium 90 and its dangers from the US EPA (although not mentioned here, it goes without saying that Strontium is present in relation to Fukushima):
“How does strontium-90 get into the environment?
Strontium-90 was widely dispersed in the 1950s and 1960s in fall out from atmospheric testing of nuclear weapons. It has been slowly decaying since then so that current levels from these tests are very low.
Strontium-90 is also found in waste from nuclear reactors. It is considered one of the more hazardous constituents of nuclear wastes. The accident at the Chernobyl nuclear power plant also introduced a large amount of Sr-90 into the environment. A large part of the Sr-90 was deposited in the Soviet Republics. The rest was dispersed as fallout over Northern Europe and worldwide. No significant amount of stronium-90 reached the U.S.
How does strontium-90 change in the environment?
As strontium-90 decays, it releases radiation and forms yttrium-90 (Y-90), which in turn decays to stable zirconium. The half-life of Sr-90 is 29.1 years, and that of Yttrium-90 is 64 hours. Sr-90 emits moderate energy beta particles, and Y-90 emits very strong (energetic) beta particles. Strontium-90 can form many chemical compounds, including halides, oxides, and sulfides, and moves easily through the environment.
How do people come in contact with strontium-90?
Everyone is exposed to small amounts of strontium-90, since it is widely dispersed in the environment and the food chain. Dietary intake of Sr-90, however, has steadily fallen over the last 30 years with the suspension of nuclear weapons testing. People who live near or work in nuclear facilities may have increased exposure to Sr-90. The greatest concern would be the exposures from an accident at a nuclear reactor, or an accident involving high-level wastes.
How does strontium-90 get into the body?
People may inhale trace amounts of strontium-90 as a contaminant in dust. But, swallowing Sr-90 with food or water is the primary pathway of intake.
What does strontium-90 do once it gets into the body?
When people ingest Sr-90, about 70-80% of it passes through the body. Virtually all of the remaining 20-30% that is absorbed is deposited in the bone. About 1% is distributed among the blood volume, extracellular fluid, soft tissue, and surface of the bone, where it may stay and decay or be excreted.
Health Effects of Strontium-90
How can strontium-90 affect people’s health?
Strontium-90 is chemically similar to calcium, and tends to deposit in bone and blood-forming tissue (bone marrow). Thus, strontium-90 is referred to as a ‘bone seeker’ Internal exposure to Sr-90 is linked to bone cancer, cancer of the soft tissue near the bone, and leukemia.
Risk of cancer increases with increased exposure to Sr-90. The risk depends on the concentration of Sr-90 in the environment, and on the exposure conditions“. http://www.epa.gov/radiation/radionuclides/strontium.html (some bold added for emphasis)
As seen above, strontium 90 is very problematic. It behaves like calcium in the body and hence incorporates itself into bone and teeth. Although half-life is considered short at 29 years, it will be in a person’s body in declining amounts for a lifetime, giving off ionizing radiation from within. Pretty scary thought.
In this context, low birthweight does not appear so important. But, what is particularly interesting about the correlation between low birthweights and strontium 90 is that it was in the post World War II economic boom years. Low birthweights are most often associated with poverty. Had it occurred during war-time when, even in the US, there was rationing of food, it would not be so visible or surprising, that ” In New York state the low birthweight percentage rose by nearly 40 percent from 1945 to 1965..”
As wikipedia explains and as many older folk know from experience: “The post–World War II economic expansion, also known as the postwar economic boom, the long boom, and the Golden Age of Capitalism, was a period of economic prosperity in the mid-20th century which occurred, following the end of World War II in 1945, and lasted until the early 1970s.” http://en.wikipedia.org/wiki/Post–World_War_II_economic_expansion

U.S.A. Newborn Deterioration in the Nuclear Age, 1945-1996

“FALLOUT AND THE PHENOMENON OF LOW BIRTHWEIGHT BABIES
The percentage of underweight live births is a far more sensitive indicator of radiation-induced harm to the newborn than either infant mortality or neonatal mortality, as established in The Enemy Within: The High Cost of Living Near Nuclear Reactors, and shown in figure 3.
In New York state the low birthweight percentage rose by nearly 40 percent from 1945 to 1965, when there had been a corresponding many-fold increase in strontium-90 found in American baby teeth. The postwar low birthweight rise is best revealed by New York, for which data begin in 1945. The low birthweight percentages are perfectly correlated with the measured geometric rise and fall in strontium-90 in the bone of New York adults for the years 1955-70. 
The low birthweight record for the USA and all states begins in 1950 and is seen to follow that of New York. After 1965 and the cessation of above-ground bomb tests, there was considerable improvement in the next decade in both the low birthweight percentage and the amount of strontium-90 found in humans. But since 1979 another slow rise has been observed in the USA low birthweight percentage in New York and every other state. This rise suggests that emissions from possibly corroding nuclear reactors may be contributing to the current deterioration of newborn viability, particularly after widespread fallout from the Chernobyl accident, which has been shown to account for otherwise inexplicable significant increases in newborn hypothyroidism, thyroid cancer and leukemia among children.

Radioactive water was found to be leaking from a storage tank at the plant last month
High levels of a toxic radioactive isotope have been found in groundwater at Japan’s Fukushima nuclear plant, its operator says. Tokyo Electric Power Company (Tepco) said tests showed Strontium-90 was present at 30 times the legal rate”.
