The Trouble with Electromagnetic Radiation
Dr. Johansson, who is a professor at the renowned Karolinska Institute in Stockholm, Sweden, recently spoke in front of an audience of health professionals and medical practitioners at a seminar on Environment in Health in Barcelona. He opened his lecture by going over the known negative health effects of EMFs, which include:
- Hypersensitivity to EMFs
- Increase in allergies and allergy symptoms
- Potential link to certain cancers
- Reducing the efficacy of certain drugs (such as Tamoxifen, which is used to treat breast cancer)
- Radiation damage
- Long-term DNA fragmentation
Dr. Johansson also discussed the logical shortcomings of those who believe EMFs are harmless, such as the idea that electro-hypersensitivity is actually just a conjured media-driven psychosis. Johansson points to studies that have easily controlled for media-driven psychosis by using test subjects like rats.  These studies have shown that EMFs have a measurable effect and are not just psychosomatic.
The evidence presented by Dr. Johansson suggests exposure to EMFs, which are created by electronic devices, has long-term cumulative effects that go as far as changing our very DNA. Johansson argues the only way to reduce these negative effects is to make some major societal changes, such as only letting children under the age of 16 (who may be more sensitive to EMFs, according to research) use cell phones for emergency calls. Johansson notes that any major change will take time, but he is determined to continue presenting the findings from his research in order to encourage that change.If you’re interested in learning more about the potential hazards of EMFs and what you can do to reduce your risk, you can watch Dr. Johansson’s entire lecture below or read more about it right here. Electric and magnetic fields are invisible areas of energy (also called radiation) that are produced by electricity, which is the movement of electrons, or current, through a wire.
An electric field is produced by voltage, which is the pressure used to push the electrons through the wire, much like water being pushed through a pipe. As the voltage increases, the electric field increases in strength. Electric fields are measured in volts per meter (V/m).
A magnetic field results from the flow of current through wires or electrical devices and increases in strength as the current increases. The strength of a magnetic field decreases rapidly with increasing distance from its source. Magnetic fields are measured in microteslas (μT, or millionths of a tesla).
Electric fields are produced whether or not a device is turned on, whereas magnetic fields are produced only when current is flowing, which usually requires a device to be turned on. Power lines produce magnetic fields continuously because current is always flowing through them. Electric fields are easily shielded or weakened by walls and other objects, whereas magnetic fields can pass through buildings, living things, and most other materials.
Electric and magnetic fields together are referred to as electromagnetic fields, or EMFs. The electric and magnetic forces in EMFs are caused by electromagnetic radiation. There are two main categories of EMFs:
