Another important factor is the distance between the worker and the source of radiation. In the case of arc welding, infrared radiation decreases rapidly as a function of distance, so that farther than three feet away from where welding takes place, it does not pose an ocular hazard anymore but, ultraviolet radiation still does. This is why ...
The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).
EMF stands for electric and magnetic fields, which, according to the National Institute of Environmental Health and Sciences, are invisible areas of energy often referred to as radiation.
The BioInitiative Report is a report on the relationship between the electromagnetic fields (EMF) associated with powerlines and wireless devices and health. It was self-published online, without peer review, on 31 August 2007, by a group "of 14 scientists, researchers, and public health policy professionals".
Martin L. Pall is professor emeritus of biochemistry and basic medical sciences at Washington State University.He is a specialist in Chronic Fatigue Syndrome, multiple chemical sensitivity, and the effects of low-intensity microwave frequency electromagnetic fields (MWV-EMF) on the human body.
Specific energy absorption rate (SAR) averaged over the whole body or over parts of the body, is defined as the rate at which energy is absorbed per unit mass of body tissue and is expressed in watts per kilogram (W/kg). Whole body SAR is a widely accepted measure for relating adverse thermal effects to RF exposure. [9]

In electromagnetic radiation (such as microwaves from an antenna, shown here) the term radiation applies only to the parts of the electromagnetic field that radiate into infinite space and decrease in intensity by an inverse-square law of power, such that the total energy that crosses through an imaginary sphere surrounding the source is the ...
