A study of real-world exposure to non-ionizing radiation from magnetic fields in pregnant women found a significantly higher rate of miscarriage, giving new evidence with respect to their potential health risks.
In the journal Scientific Reports (Nature Publishing Group) the Kaiser Permanente study was published. Non-ionizing radiation from magnetic fields is produced when electric devices are being used and electricity is streaming.
It can be produced by various environmental sources, including electric appliances, electrical lines and transformers, wireless devices and wireless systems.
People are exposed to magnetic fields by means of close to these sources while they are being used. Women with the highest measured exposure level of magnetic field non-ionizing radiation had a nearly three times higher relative risk of miscarriage.’
De-Kun Li, MD, PhD, principal investigator of the study and a reproductive and perinatal epidemiologist at the Kaiser Permanente Division of Research in Oakland, California said, while the health hazards to people from non-ionizing radiation stays limited from ionizing radiation are settled and incorporate radiation sickness, cancer and genetic damage, the evidence of health risks.
Dr. Li said, “Few studies have possessed the ability to accurately measure exposure to magnetic field non-ionizing radiation”.
“Moreover, because of the current lack of research regarding this matter, we don’t have the biological idea about which problems may develop, and we additionally don’t yet understand the possible mechanisms for increased risks.”
In a new study funded by the National Institute of Environmental Health Sciences, researchers asked women over age 18 with confirmed pregnancies for 24 hours to wear a little (somewhat bigger than a deck of cards) magnetic field monitoring device.
Members additionally kept a journal of their activities on that day and were interviewed in person to better control for possible confounding factors, as well as how typical their activities were on the monitoring day.
Analysts controlled for numerous factors known to influence the risk of miscarriage, including nausea/vomiting, past history of miscarriage, liquor use, caffeine intake, and maternal fever and infections.
Objective magnetic field measurements and pregnancy results were obtained for 913 pregnant women, all individuals from Kaiser Permanente Northern California.
In 10.4 percent of the women, miscarriage occurred with the most minimal measured exposure level (first quartile) of magnetic field non-ionizing radiation on a normal day, and in 24.2 percent of the women with the higher measured exposure level (second, third and fourth quartiles), a nearly three times higher relative risk.
Dr. Li said the rate of miscarriage reported in the general community is between 10 and 15 percent.
He said, “This examination gives evidence from a human populace that magnetic field non-ionizing radiation could have adverse biological effects on human health”.
Qualities of this examination, Dr. Li noted, included that researchers utilized a target measuring device and studied a short-term result (miscarriage) instead of one that will happen years or decades later, for example, cancer or autoimmune diseases.
The study’s principal limitation is that it was not feasible for specialists to request that members carry the measuring device all through pregnancy. Dr. Li noticed that the potential health risk of magnetic field non-ionizing radiation needs more research.
“We hope that the finding from this examination will stimulate much-needed additional studies into the potential environmental risks to human health, including the health of pregnant women.”
