5 New Russian Studies Non-Ionizing Radiation 3.30.11

March 30, 2011
New Studies by Prof. Yuri Grigoriev et al, Biophysics, 2011, Chairman of the Russian National Committee on Non-Ionizing Radiation Protection, Moscow (Russian Federation)

Five new papers have been published on radiobiology and radioecology that address non-thermal (low-intensity) radiofrequency radiation exposures at cell phone and wireless frequencies. Dr. Yuri Grigoriev is a highly regarded research scientist who has a long history of publishing in the area of biologic and human health impacts from non-ionizing radiation.

Grigoriev was also a contributing author to the Seletun Scientific Statement (Seletun, Norway, 2009).  As Chairman of the Russian National Committee on Non-Ionizing Radiation, he was an early advocate of limiting cell phone use in pregnant women and children back as early as 2002.

Part 5.  Study of the Influence of Blood Serum from Rats Exposed to Low-Level Electromagnetic Fields on Pregnancy and Fetal and Offspring Development.

The objective of this 2005-2007 research program profiled here was to repeat experimental studies done by Shandala, Vinogradov Rudnev, Dumanskyi et al between 1974 and 1991.  Those studies reported effects on the immume system and on reproductive outcomes in animal studies with exposure to low-level, nonthermal RF EMF. 

The Grigoriev et al studies were conducted according to the World Health Organization protocol from the International EMF Program, with oversight by external experts including WHO EMF Program Manager Michael Repacholi.  The experimental results and general conclusions were endorsed by the WHO and the International Advisory Committee.

In his five-part series of papers in Biophysics, Grigoriev et al has validated research findings of the earlier Soviet studies.  Effects on immunological and reproductive functions from long-term, low-level exposure of rats to radiofrequency electromagnetic fields (RF EMF) were replicated.
Grigoriev writes,  “(T)he results of this work, along with investigations concerning chronic, low-level EMF exposure, can be used for the evaluation of the danger of RF EMF of base stations on public health.”

Part 1 covers general conclusions of the research, and confirms that experimental results previously obtained in the USSR showing possible adverse effects of serum of rats irradiated with RF EMF (30 days, 7 h a day, RF exposure of 500 uW/cm2)* on pregnancy and fetal and offspring development.  Induction of autoimmune response (the formation of antibodies to brain tissues) were also reported under the same exposure conditions.

Part 1 also provides measurements of mobile communication base station RF EMF exposures.  Tables 1 and 2 have measurements from 220 stations taken before 2004.  Table 3 has newer measurements from 2008 for 118 base stations.

Part 2 describes the conditions for handling and exposure of the test animals (rats) to RF EMF at 500 uW/cm2 at 2450 MHz for 30 days, 7 h per day.   Methods for verifying exposures are described.  On the 7th and 14th days after completion of RF EMF exposure, the rat tissues were subjected to immunological and teratology tests.  Parts 3,4 and 5 summarize the results of tests.

Part 3 reports that long-term, nonthermal exposure resulted in a statistically significant increase in the level of antibodies in brain and liver tissues in blood serum.

Part 4 reports that RF EMF exposure as described above resulted in a significant increase in the amino acids and antibodies that are clear markers for cellular stress.  The data indicate that long-term exposure to low-level RF EMF triggers the stress response of the organism.  “It may well be that irradiation causes formation of antibodies against the compounds yielded by interactions of the reactive oxygen species and nitric oxide with intracellular molecules.  The maximum effect was observed on the seventh day after exposure to microwave-frequency EMF.”

Part 5 reports that blood serum from rats exposed to RF EMF for one month, 7 h per day, had changes in their blood serum, so that when this blood was injected into another group of pregnant rats, the result was adverse effects on fetal and offspring development, and higher in utero and postnatal mortality.  In other words, simply injecting blood serum from RF EMF-exposed animals into other, pregnant animals negatively affected pregnancy and fetal development.

Negative effects included lower fertility, disturbances in the birthing process, trauma to the newborns, more fetal deaths, more deaths among the newborn, and delayed physical development of the offspring.

 “Thus, comparative analysis of the data indicate that the injection of 1 ml of blood serum of animals subjected to long-term exposure to RF EMF into rats in their tenth day of pregnancy negatively influences pregnancy and fetal development.”

“Analysis of cross-feeding of irradiated and control offspring allow us to conclude that the processes (immune and other) which appear in the organism of females (mother) due to introduction of blood serum from irradiated EMP animals exert a pronounced embryotoxic effect on fetal development.”

Not only have the Grigoriev et al papers validated earlier Soviet research findings but perhaps have provided understanding of the findings of some newer studies.
For example, in Divan et al, 2008, the authors reported that maternal use of a cell phone during pregnancy resulted in a statistically significant increase in behavioral problems and learning in the children by the time they were of school age.

RF EMF has been demonstrated to affect immune status and function in women, and to cause allergic reactions and stress responses (heat shock proteins or hsp).  The BioInitiative Report (Chapter 8 – Immune Function) reports a long history of studies documenting allergic and inflammatory conditions with EMF exposure in general. Inflammatory responses to illness in mothers during pregnancy has been suggested as a plausible biological mechanism for altered brain development in the child, with potential impacts on mental health (Scientific American, April 2008, Melinda Wenner).
 *Footnote: These exposures at 500 UW/cm2 are far higher than recent studies of base stations, but reflect some very high measured exposures characteristic of some Russian cities.  The eight or so studies of populations living near ‘masts’ reported by Kundi, 2009 have average RF exposures of a fraction of a microwatt/cm2 to several microwatts/cm2.
