Environmental electromagnetic field

At very weak fields, it is sometimes possible to observe an increase in the rate of S-T mixing, which in Fig. 8.6 corresponds to an increase in geminate product yield. This is known as a low-field effect (LFE) and has been a topic of interest recently due to the interest in the effect of environmental electromagnetic fields on human health and... 

Electromagnetic fields (EMF) can exert biological effects. Epidemiological studies hypothesized that EMF exposure may be linked to an increased risk of leukemia and cancer. The production of reactive oxygen species (ROS) is considered a possible route for cellular damage in presence of environmental electromagnetic fields, through their effects on the spin procession rates of unpaired electrons with consequent effects on the radical lifetime. ...

I could feel and sense input from all manner of environmental elements and food and so forth. At the time I had no context for what was happening, and felt quite mad. Some of what I considered madness at the time was actually my having been acutely perceptive and acutely accurate about what I felt and sensed. Those of us with chemical and electromagnetic field sensitivities have extra senses. I have no way to accurately describe these to people who have never experienced it. It is a true advantage in many respects, but it s weird being that odd person who can sense trouble—that the power lines are leaking or the gas line is leaking. 

Find the structure parameters x and the properties y of a given compound at room temperature and pressure. What are the properties of the compound at elevated or lowered temperatures and pressures, as well as of other environmental variables, such as electromagnetic field and solar radiation, so that this search can be written as y = f x, T, P)1... 

The pace in the development of electromagnetic field (EMF) technologies and the ever-increasing number of commercial applications in all areas and activities of our life is breathtaking. This is particularly true of radio frequency wireless technologies and telecommunications. Nowadays, especially in urban environments, exposure to human-made EMFs is an unavoidable fact of life, and understanding its potential health effects and possible environmental impacts and risks, a priority.

To see that, let us focus on a couple of factors that mainly determine the economy of the EB remediation process i.e. a high power (by which high volumes of water can be rehabilitated daily), and the efficiency (which establishes the transfer rate ofthe accelerator nominal power into useful energy). To this respect, it is instructive to learn from Table 2 that DC and UHF machines (Chapter 2) best match with these requirements. In the DC type machines, electrons are accelerated by a direct-current field, while in the UHF type, acceleration occurs across an electromagnetic field oscillating at few hundreds MHz. These accelerators achieve high powers coupled with moderately-high efficiencies, and therefore represent the best choice for wastewater treatment. At present, the linear accelerators, which are based on a microwave field, show efficiencies and power below the others, such that they are not suitable for environmental purposes. 

In older literature, "electromotive force," which is voltage. In modem usage, it means "electromagnetic fields," which includes radio waves, magnetism from power transformers, and similar fields. Some environmental scientists say that it can be damaging to human beings, but others say it is harmless. 

The electric, magnetic, and electromagnetic fields became a serious factor of everyday life of all living systems, starting from occupational and everyday life of human population, as well as for the entire biosphere. While considering environmental impact of these factors, science must dedicate serious attention to potential benefit of using EMF for human health.
