French researchers have confirmed that childhood leukemia rates are shockingly elevated among children living near nuclear power reactors.
The “International Journal of Cancer” has published in January a scientific study establishing a clear correlation between the frequency of acute childhood leukemia and proximity to nuclear power stations. The paper is titled, “Childhood leukemia around French nuclear power plants – the Geocap study, 2002-2007.”
This devastating report promises to do for France what a set of 2008 reports did for Germany — which recently legislated a total phase-out of all its power reactors by 2022 (sooner if the Greens get their way).
The French epidemiology — conducted by a team from the Institut National de la Santé et de la Recherche Médicale, or INSERM, the Institut de Radioprotection et de Sûreté Nucléaire, or IRSN, and the National Register of hematological diseases of children in Villejuif, outside Paris — demonstrates during the period from 2002-2007 in France the doubling of childhood leukemia incidence: the increase is up to 2.2 among children under age five.
The researchers note that they found no mechanistic proof of cause and effect, but could identify no other environmental factor that could produce the excess cancers.
Without getting overly technical, the case-control study included the 2,753 cases of acute leukemia diagnosed in mainland France over 2002-2007, and 30,000 contemporaneous population “controls.” The children’s last addresses were geo-coded and located around France’s 19 nuclear power stations, which operate 54 separate reactors. The study used distance to the reactors and a dose-based geographic zoning, based on the estimated dose to bone marrow related to the reactors’ gaseous discharges.
All operating reactors routinely spew radioactive gases like xenon, krypton and the radioactive form of hydrogen known as tritium. These gases are allowed to be released under licenses issued by federal government agencies. Allowable limits on these radioactive poisons were suggested to governments and regulatory agencies by the giant utilities that own the reactors and by reactor operators themselves. This is because their reactors can’t even function without regularly releasing radioactive liquids and gases, releases required to control pressure, temperature and vibrations inside the gigantic systems. (See: “Routine Radioactive Releases from Nuclear Power Plants in the United States: What Are the Dangers?” from BeyondNuclear.org, 2009)
In Germany, results of the 2008 KiKK studies — a German acronym for Childhood Cancer in the Vicinity of Nuclear Power Plants — were published in both the International Journal of Cancer (Vol. 122) and the European Journal of Cancer (Vol. 44). These 25-year-long studies found higher incidences of cancers and a stronger association with reactor installations than all previous reports. The main findings were a 60 percent increase in solid cancers and a 117 percent increase in leukemia among young children living near all 16 large German nuclear facilities between 1980 and 2003. These shocking studies — along with persistent radioactive contamination of Germany from the Chernobyl catastrophe — are largely responsible for depth and breadth of anti-nuclear public opinion all across Germany.
Similar leukemia spikes have been found around U.S. reactors (European Journal of Cancer Care, Vol. 16, 2007). Researchers at the Medical University of South Carolina analyzed 17 research papers covering 136 reactor sites in the UK, Canada, France, the U.S., Germany, Japan and Spain. The incidence of leukemia in children under age 9 living close to the sites showed an increase of 14 to 21 percent, while death rates from the disease were raised by 5 to 24 percent, depending on their proximity to the nuclear facilities.
When the U.S. public owns up to the dangers of nuclear power, we too can get around to its replacement and phase-out.
