Study: Radiation affects birth sex ratio
Published: May 26, 2011 at 4:00 PM

MUNICH, Germany, May 26 (UPI) -- Exposure to nuclear radiation has a genetic effect on humans leading to an increase in male births relative to female births, German researchers say.

Hagen Scherb and Kristina Voigt of the Helmholtz Zentrum Munchen said their study shows radiation from atomic bomb testing before the Partial Test Ban Treaty in 1963, the Chernobyl accident and from living near nuclear facilities has had a long-term effect on the ratio of male to female human births, an article in the journal Environmental Science and Pollution Research reported.

Ionizing radiation from nuclear activity is known to have mutagenic properties and is likely to have detrimental effects on human reproduction, they said.

"Our results contribute to disproving the established and prevailing belief that radiation-induced hereditary effects have yet to be detected in human populations," Scherb and Voigt wrote. "We find strong evidence of an enhanced impairment of humankind's genetic pool by artificial ionizing radiation."

Nuclear Radiation Affects Sex of Babies, Study Suggests

ScienceDaily (May 27, 2011) — Ionizing radiation is not without danger to human populations. Indeed, exposure to nuclear radiation leads to an increase in male births relative to female births, according to a new study by Hagen Scherb and Kristina Voigt from the Helmholtz Zentrum München.

<snip>

Their analyses show a significant male-female gap in all three cases:
* Increases in male births relative to female births in Europe and the US between 1964-1975 are a likely consequence of the globally emitted and dispersed atmospheric atomic bomb test fallout, prior to the test ban in 1963, that affected large human populations overall after a certain delay.
* There was a significant jump of sex odds in Europe in the year 1987 following Chernobyl, whereas no such similar effect was seen in the US, which was less exposed to the consequences of the catastrophe.
* Among populations living in the proximity of nuclear facilities (within 35km or 22 miles), the sex odds also increased significantly in both Germany and Switzerland during the running periods of those facilities.

Taken together these findings show a long-term, dose-dependent impact of radiation exposure on human sex odds, proving cause and effect. What is less clear is whether this increase in male births relative to female births is the result of a reduced frequency of female births or an increased number of male births. The authors estimate that the deficit of births and the number of stillborn or impaired children after the global releases of ionizing radiation amount to several millions globally.

Among the conclusions in the paper:

5 Conclusions and outlook

Our observations add evidence to findings in the field of
radiation epidemiology indicating considerably underestimated
health risks of the so-called low-level (< 100 mSv)
ionizing radiation ...
This means that the internationally established radiation
risk concept based on average absorbed dose is in error at
three to four orders of magnitude or, more likely, it is
conceptually wrong.

Concealing the Consequences

Chernobyl 25 Years Later

2. MUST READ/REVIEW:

(This 349-page comprehensive survey of the scientific literature utilizes extensive citations of peer reviewed journal articles, including examination of changes in male/female sex ratios. My recollection is that fewer boys are born.)

http://www.strahlentelex.de/Yablokov%20Chernobyl%20book.pdf

Chernobyl: Consequences of the Catastrophe for People and the Environment

Yablokov, A.V., Nesterenko, V.B., and Nesterenko, A.V., Sherman-Nevinger, J.D., Consulting Editor, Chernobyl: Consequences of the Catastrophe for People and the Environment, New York Academy of Sciences, 1181:1-327, 2009.

EXCERPT:

"This book had been nearly completed when Prof. Vassily Nesterenko passed away on August 23, 2008. He was a great person who, like Andrey Sakharov, stopped his own bright professional nuclear career as the general design engineer of the Soviet Union’s mobile nuclear power plant “Pamir” and director of Belarussian Nuclear Center to devote his life’s efforts to the protection of humankind from Chernobyl’s radioactive dangers."

- ALEXEY V. YABLOKOV

3. RECENT SHORT ARTICLE OVERVIEW OF #2:

http://www.ratical.org/radiation/Chernobyl/CCofC25YL.html
Chernobyl: Consequences of the catastrophe 25 years later
by Janette D. Sherman, M.D., and Alexey V. Yablokov, Ph.D
San Francisco Bay View
April 27, 2011

EXCERPTS: This article was solicited by the Bulletin of Atomic Scientists in 2010, but after Dr. Sherman had responded to 42 queries and spent 30 hours writing it, it was rejected shortly before the deadline, apparently as too alarming. This paragraph is an ominous warning of the Fukushima catastrophe that occurred just a few months after it was written and a reminder of the urgent need for more public information such as is provided here. See also: Is the Fukushima nuclear plant breakdown worse than Chernobyl? by Janette D. Sherman, M.D.

<...>

Reproductive system:

A wide spectrum of reproductive function disorders and urogenital morbidity exists in those living in contaminated territories. These include abnormal development of the genitalia, sperm pathologies, including dead sperm, low sperm mobility, disorders of secondary sexual characteristics, degenerate changes of the placenta, delay in sexual maturation, primary infertility, complications during pregnancy and birth, and perinatal and neonatal deaths.

Significantly high levels of alpha radionuclides were found in bone tissue of aborted fetuses from mothers living in the contaminated territories in Ukraine. Changes in sex ratios at birth were documented in Denmark, Finland, Germany, Hungary, Norway, Poland and Sweden. (citations provided in 324 page PDF)

Genetic changes:

Chromosome aberrations in peripheral blood cells were among the first ominous signs of the Chernobyl catastrophe and revealed a correlation between the level of aberrations and a number of pathological conditions. Somatic chromosomal mutations were linked to congenital malformations and protein polymorphism. Mutations in mini-satellite DNA are only some of the genetic changes resulting from radionuclide exposure, but the overwhelming majority of Chernobyl-induced genetic changes will not become apparent for several generations.

Throughout her career, she has served as a medical-legal expert witness for thousands of individuals harmed by exposure to toxic agents. Dr. Sherman's primary interest is the prevention of illness through public education and patient awareness. She can be reached at toxdoc.js@verizon.net and www.janettesherman.com. Co-author Alexey V.

Debate over health effects of Chernobyl re-ignited

Controversy surrounding the true toll and disease burden caused by fallout from the Chernobyl nuclear disaster in 1986 has resurfaced following the release of a new study. Ed Holt reports

...Ukrainian authorities have designated 2·4 million Ukrainians, including more than 400 000 children, as having health problems related to the disaster. Wertelecki says that the most important thing now was to begin wide-scale studies to try to identify the cause of birth defects in the region and prevent them...

For the birth defects study see Pediatrics 2010; 125: 836–43

7. On the other hand ...
... if they were using either China or India as their data source,
they would have obviously concluded that both nations had suffered
from devastating nuclear accidents years ago ...
