Non-ionizing Radiation from Magnetic Fields and Their Health Risks

A find out about of real-world publicity to non-ionizing radiation from magnetic fields in pregnant ladies discovered a considerably upper price of miscarriage, offering new proof relating to their possible well being dangers. The Kaiser Permanente find out about used to be revealed these days within the magazine Scientific Reports (Nature Publishing Group).


Non-ionizing radiation from magnetic fields is produced when electrical units are in use and electrical energy is flowing. It may also be generated by way of quite a few environmental assets, together with electrical home equipment, energy strains and transformers, wi-fi units and wi-fi networks. Humans are uncovered to magnetic fields by the use of shut proximity to those assets whilst they’re in use.

‘Women with the highest measured exposure level of magnetic field non-ionizing radiation had a nearly three times higher relative risk of miscarriage.’

While the well being hazards from ionizing radiation are well-established and come with radiation illness, most cancers and genetic injury, the proof of well being dangers to people from non-ionizing radiation stays restricted, stated De-Kun Li, MD, PhD, essential investigator of the find out about and a reproductive and perinatal epidemiologist on the Kaiser Permanente Division of Research in Oakland, California.

“Few studies have been able to accurately measure exposure to magnetic field non-ionizing radiation,” Dr. Li stated. “In addition, due to the current lack of research on this subject, we don’t know the biological threshold beyond which problems may develop, and we also don’t yet understand the possible mechanisms for increased risks.”

Study Overview

In a brand new find out about funded by way of the National Institute of Environmental Health Sciences, researchers requested ladies over age 18 with showed pregnancies to put on a small (a little greater than a deck of playing cards) magnetic-field tracking tool for 24 hours. Participants additionally stored a diary in their actions on that day, and have been interviewed in individual to higher keep an eye on for imaginable confounding elements, in addition to how conventional their actions have been at the tracking day. Researchers managed for a couple of variables identified to steer the chance of miscarriage, together with nausea/vomiting, previous historical past of miscarriage, alcohol use, caffeine consumption, and maternal fever and infections.

Objective magnetic subject measurements and being pregnant results have been bought for 913 pregnant ladies, all contributors of Kaiser Permanente Northern California. Miscarriage took place in 10.four p.c of the ladies with the bottom measured publicity stage (1st quartile) of magnetic subject non-ionizing radiation on a standard day, and in 24.2 p.c of the ladies with the upper measured publicity stage (second, third and 4th quartiles), a just about thrice upper relative chance. The price of miscarriage reported within the normal inhabitants is between 10 and 15 p.c, Dr. Li stated.

“This study provides evidence from a human population that magnetic field non-ionizing radiation could have adverse biological impacts on human health,” he stated.

Strengths of this find out about, Dr. Li famous, integrated that researchers used an purpose measuring tool and studied a non permanent result (miscarriage) somewhat than one that may happen years or a long time later, similar to most cancers or autoimmune illnesses. The find out about’s major limitation is that it used to be now not possible for researchers to invite contributors to hold the measuring tool during being pregnant.

Dr. Li famous that the possible well being chance of magnetic-field non-ionizing radiation wishes extra analysis. “We hope that the finding from this study will stimulate much-needed additional studies into the potential environmental hazards to human health, including the health of pregnant women.”
