Laptop computer Electromagnetic Fields (EMFs), also known as Electromagnetic Radiation (EMR), are harmful to users and a particular health risk to pregnant women and their unborn fetuses. In 2012, a European journal released a study that links radiation emissions from laptop computers to low currents in the human body thus, increasing the potential for health problems. The study suggests that there should be actions taken by standards organizations and users to reduce these exposures. In the meantime, consider radiation protection from laptops as well as tablets and other handheld electronic devices.
Early in 2012, the Environmental & Occupational Health Publication published the article Exposure to Electromagnetic Fields From Laptop Use of “Laptop” Computers. The abstract says that laptop computers are often used in close contact with the body. They conclude that laptops generate Electromagnetic Radiations (EMRs), also known as a magnetic flux, that induce currents in the body. This study investigates if there are health concerns when exposed to these fields, with particular emphasis on women and their fetus. The study concluded that Swedish EMF standards were exceeded by 71–483% which, by the standard’s definition, increases risk for tumor development. They also say that laptops are contacting the body in a very delicate area close to skin, bones, blood, genitals, and, in pregnant women, close to the fetus. These laptops have electrical circuits and power supplies that produce Electromagnetic Radiation (EMR) causing detectable impairment to the health of the exposed individual or his or her offspring.
Five laptop computers from different manufacturers were studied in a laboratory to determine radiation emissions. Measurements were taken using highly specialized and sensitive testing equipment to find the field density, a measurement of power and strength. The higher the density, the more likely currents are created in the body. The researchers correlated their findings into a large database of average pregnant woman developed by National Institute of Information and Communications Technology and Ciba University. This merge of data enabled the study to acutely determine, with statistical significance, how patterns of exposure impact the health of pregnant women and their fetus.
The study concludes that a mother and fetus are exposed to higher amounts of EMRs by laptops than those found in close proximity of high-voltage power lines or video screens. EMF values were higher than the values recommended by 2 recent guidelines for computer monitor magnetic field emissions and considered a risk for the development of blood tumors.
The authors reviewed study data from many sources and concluded that the effects of Electromagnetic Radiation (EMR) in some studies failed to link low-intensity Electromagnetic Radiation (EMR) and tumors while others reports found clear adverse effects impacting heart rate, sleep, and other health concerns. In part, they observe, that the studies that found no links, were never intended to find links.
The authors recommend reducing exposure to Electromagnetic Radiation (EMR) and agree with World Health Organization (WHO) recommendations that devices, like laptops should be reengineered to lower emissions. They go on to say that laptops are a source of increased EMR exposure and that users should be aware of increased health risks, particularly during pregnancy.
Consider laptop radiation protection and other hand-held devices until technologies are developed to emit less Electromagnetic Radiation (EMR).
