Definitions

The properties and effects of non-ionising radiations are very diverse. For the purpose of this Policy non-ionising radiations include:

Extremely low frequency (ELF) radiation

Electromagnetic radiation with frequencies in the range 0 Hz (static fields) to 3 kHz, including the 50 Hz electric and magnetic fields associated with the domestic mains electricity supply such as in domestic electrical appliances, electricity supply substations and overhead power lines.

Radiofrequency (RF) radiation

Electromagnetic radiation with frequencies in the range 3 kHz to 300 GHz, which is produced by artificial sources such as visual display units and mobile phones.

Microwave (MW) radiation

Electromagnetic radiation with frequencies in the range 1 GHz to 300 GHz, which is produced by artificial sources such as in microwave ovens and by microwave communication devices. (This radiation is now considered part of Radiofrequency radiation.)

Infrared (IR) radiation

Electromagnetic radiation with wavelengths between 700 nm and 1 mm, which is present in sunlight and produced by artificial sources such as electric radiator heaters.

Visible light

Electromagnetic radiation with wavelengths between 400 nm (blue) and 700 nm (red), which is present in sunlight and produced by numerous artificial sources, including lasers.

Ultraviolet (UV) radiation

Electromagnetic radiation with wavelengths between 100 nm and 400 nm, which is present in sunlight as well as produced by artificial sources such as arc welding and sterilization lamps.

Electric fields

Magnetic fields

  1. Electric fields arise from voltage.
  2. Their strength is measured in Volts per metre (V/m)
  3. An electric field can be present even when a device is switched off.
  4. Field strength decreases with distance from the source.
  5. Most building materials shield electric fields to some extent.
  1. Magnetic fields arise from current flows.
  2. Their strength is measured in amperes per meter (A/m). Commonly, EMF investigators use a related measure, flux density (in microtesla (µT) or millitesla (mT) instead.
  3. Magnetic fields exist as soon as a device is switched on and current flows.
  4. Field strength decreases with distance from the source.
  5. Magnetic fields are not attenuated by most mat

SAFE WIRELESS INITIATIVE ALERT

Issued September 25, 2006
Washington, D.C. —- A new qualitative risk assessment conducted by SWI staff, prompted in part by the recent confirmation of severe lung disorders among first responders and firefighters following the World Trade Center terrorist attacks on September 11, 2001, indicates an urgent need for preventive intervention steps to be taken among these groups.  SWI is particularly concerned that firefighters – with jobs among the most hazardous in society – are in danger of suffering serious illness derivative of synergies among electro-magnetic radiation, toxic chemical exposures, biological disease agents, and debilitating post-traumatic stress.  The problem is further exacerbated by both the continually growing dependence of emergency responders on wireless communications and the tendency of current wireless infrastructure build-out to include firehouses and other emergency triage units.

“Research by the National Power Laboratories in Wisconsin shows that the average electronic machines modems, computers, etc.) experiences 3,000 transient events every month. Roughly 15% of all server crashes are caused by electromagnetic interference problems. These glitches cost U.S. industry $26 billion and the projected growth of this problem is at about 15% a year. Transients cause problems such as software crashes, hardware damage, and data loss or corruption. They all disrupt operations and cause economic losses. Transients can also have negative effects on human health. The greater the speed and the smaller microprocessors become, this makes them vulnerable to radiated and/or induced electromagnetic fields.

The internal configuration of the modern microprocessor is so compact that it is much more usceptible to electrical disturbances. The best way to cancel out the effects of undesirable transmissions is to screen electronic components from such sources. Organizations and applications ost affected by such problems include but are not limited to… Internet service providers, corporate
computer rooms, telecommunication and computer networks, e-Commerce facilities, electronic testing labs, banks, stock markets, industrial machinery, air-traffic control rooms, and many others.”

Thought-Styles….there are two fundamentally different approaches to doing science in the 1990s – two distinct scientific thought-styles. In the physical thought-style, the goal is to explain an observation by showing that it is compelled by basic physical laws or at least by phenomenological equations. In this thought-style, a scientific fact is a deduction from a relevant covering law made in the context of particular assumptions. The concept of causality does not occupy a central position in the physical thought-style because the necessary and sufficient cause of the observation to be explained – a force – is known in advance of the explanation.

In contrast, in the biological thought-style, the goal is to establish a scientific fact. In this thought-style, a scientific fact is a but-for cause of an observation established using orthodox measurement methods and appropriate statistical techniques. In the biological thought-style, covering laws are not employed and linkage with covering laws, even in principle, is not required as a precondition for accepting observations as valid. Scientific facts are generalizations that admit of exceptions.

… two distinct thought-styles were utilized to produce scientific facts applies equally well to all subsequently published issues of Science that I have considered…each report in any issue of Science that involves formal reasoning can be classified into one (or a combination) of the thought-styles described here. It can permissibly be concluded, therefore that there presently exist two distinct valid methods for producing scientific knowledge. Consequently, the scientific facts of the physicist and the biologist are fundamentally different objects. This analysis makes clear – I think for the first time – that there presently are two distinct pathways by which observations can rise to the level of scientific fact…. failure to distinguish between the thought-styles and to identify the applicable thought-style accounts, in part, for the present controversy regarding whether powerline EMFs affect human health.

It’s not either/or, folks. We need to put our heads together.

“..Electromagnetic radiation can be described in terms of a stream of photons, each traveling in a wave-like pattern, moving at the speed of light and carrying some amount of energy. … the only difference between radio waves, visible light, and gamma-rays is the energy of the photons. Radio waves have photons with low energies, microwaves have a little more energy than radio waves, infrared has still more, then visible, ultraviolet, X-rays, and gamma-rays.””Actually, the amount of energy a photon has makes it sometimes behave more like a wave and sometimes more like a particle. This is called the “ wave-particle duality” of light. …only in how it behaves. Low energy photons (such as radio) behave more like waves, while higher energy photons (such as X-rays) behave more like particles. …the electromagnetic spectrum can be expressed in terms of energy, wavelength, or frequency. Each way of thinking about the EM spectrum is related to the others in a precise mathematical way. The relationships are:
the wavelength equals the speed of light divided by the frequency
or
lambda = c / nu” http://imagine.gsfc.nasa.gov/docs/science/know_l2/emspectrum.html

“Biological effects of extremely low-frequency electromagnetic fields (ELF-EMF) on microcirculation were investigated in vivo by monitoring arteriole diameters in conscious mice. Measurements of blood vessel diameter were monitored 33 min non-stop before during and after exposure with ELF-EMF and every 389 ms blood vessel diameter were calculated….Since vessel diameters exhibit rhythmic variation expressed by vasomotion, for estimation of microcirculatory activity….. with the aim to evaluate possible changes in mean blood vessel diameter as a result of ELF-EMF action.”

 

“During EMF exposure and post-exposure periods, arteriole diameters increased significantly compared with the pre-exposure period, and the changes were larger during post-exposure. In contrast to sham exposure, vasodilatation of the microvasculature was significantly greater during exposure and post-exposure to 16 Hz EMF. These findings suggest that ELF-EMF may have potential therapeutic use benefit for treating vascular disorders.”

“Opposition is …strong in residential areas. Washington attorney….represents several cell phone companies, estimated that more than 500 cases have been heard nationwide involving efforts to stop cell phone towers and antennas. In most cases, the cell phone companies have won.”

“That’s in part because federal law eliminates one of the key arguments against cell sites — the health factor. No studies have shown conclusive evidence that radio-frequency emissions are harmful at levels allowed by the Federal Communications Commission. As a result, the law prohibits rejection of a tower based on health risk.

Yet fear of the uncertainty remains. A year ago, the International Association of Fire Fighters opposed the use of fire houses for cell sites “until a study with the highest scientific merit” proves they are safe.

“The American Cancer Society’s website says that because the technology is still relatively new, “we do not yet have full information on health effects.” However, the organization noted there was no known evidence of a link between low-level emissions and cancer.”

“Still, the perception of a health risk, combined with what some consider an eyesore, can lower property values for those living near a cell site, O’Brien said.”

“The EMF exposures for many jobs have not been measured, but the following table shows average exposures to magnetic fields for typical workers who use electric equipment. Exposures during a work shift vary with the strength of the magnetic field, the worker s distance from the EMF source, and the time the worker spends in the field. For comparison, the table also lists worker exposures off the job.”

“Average magnetic field exposures for various types of workers (in milligauss*)”

                                    Average daily exposures
        Type of worker                 Median**     Range
Workers on the job:
    Clerical workers without
       computers                       0.5       0.2 - 2.0
    Clerical workers with
       computers                       1.2       0.5 - 4.5
    Machinists                         1.9       0.6 - 27.6
    Electric line workers              2.5       0.5 - 34.8
    Electricians                       5.4       0.8 - 34.0
    Welders                            8.2       1.7 - 96.0
 
 Workers off the job
    (home, travel, etc.)               0.9       0.3 - 3.7

*Magnetic fields are often measured in gauss or milligauss (one thousandth of a gauss = 1 milligauss).
**The median is the middle measurement: half the workers have average daily exposures above this point and half below.”

“Every (electric) current going through a wire generates magnetic radiation which travels around the wire. There is continuing controversy regarding possible health effects of exposure to this radiation. The U.S. Environmental Protection Agency (EPA) and the U.S. Navy performed a study which reported that 5 out of 6 laboratories found increased levels of embryological changes in chickens when exposed to magnetic radiation. Other tests have shown biological effects on mice, miniature pigs, and humans. Recent articles claim or at least suspect that exposure to high levels of ELF radiation is a factor in leukemia in children….

“Magnetic radiation surveys measure Extremely Low Frequency (ELF) and Very Low Frequency (VLF) fields which have nothing to do with high frequency radioactivity such as radon, X-rays, and so-called ionizing radiation… Magnetic radiation is produced by high tension power lines, but also by ordinary secondary lines, power transformers, household wiring, certain electric radiant heating devices, improperly grounded appliances.”
