United Federation Of Teachers - Are Computers Hazardous to your Health?

 i  Stress & Electromagnetic Fields & Radiation
 i  In addition, computers emit " low frequency" (ELF) electromagnetic fields. i  Q: Is exposure to electromagnetic fields & radiation a health hazard?  i  However, there is an open question about the long-term effects of the lower frequency, less powerful non-ionizing radiation associated with computers & microwave ovens & the low frequency electromagnetic fields associated with electrical current.  i  But recent research has shown that some types of low frequency electromagnetic energy can harm lab animals. In addition, some epidemiological research (...) has suggested that workplace exposure to low frequency electromagnetic fields & radiation may be associated with miscarriages, birth defects & cancer. i 
 i  Q: Are there any government standards to protect workers against exposure to electromagnetic fields & non-ionizing radiation from computers?  i 
 i  A: According to Mark Pinsky’s The EMF Book: What You Should Know About Electromagnetic Fields, Electromagnetic Radiation & Your Health, screens that fit on the front of the monitor aren't effective in reducing electromagnetic emissions. i 
 i  Q: You said that low frequency (ELF) electromagnetic fields are produced by all electrical equipment & appliances. i

VDT Guide: Radiation

 i  Another issue of concern for the VDT operator is whether the emission of non-ionizing radiation (...) & ionizing radiation (...) pose a health risk. Throughout the 1980's, many epidemiological studies were performed to determine the health hazards related to VDT use. The studies to date don't provide any conclusive evidence that the low levels of radiation emitted from VDTs pose a health risk to VDT operators. The threat from X-ray exposures is largely discounted as of the low emission levels. The radio frequency & low frequency electromagnetic fields emitted by VDTs aren't considered a problem for VDT users by most experts. However, potential health effects from exposure to electromagnetic fields, particularly those associated with high voltage systems, eg ?  high voltage overhead electrical lines, continue to be studied. The individual most sensitive to radiation effects is the developing fetus. In 1991, a long awaited National Institute of Occupational Safety & Health (NIOSH) study was published offering reassurance to women who work with VDTs. The researchers found that occupational VDT use was not associated with increased risk for spontaneous abortion. i

 i  For our research project we will analyze the effect on low level EMF frequencies upon various species of plant lifes root systems. This closely relates to every day life as these low level EMFs are similar to those put out by house hold appliances. i  The news media regularly covers many areas of the controversy over the possible health effects of electromagnetic fields. i  Sometimes electromagnetic radiation is called EMR, while electromagnetic fields are frequently referred to as EMF. EMR & EMF refer to the entire range of the electromagnetic spectrum, from low frequencies to radio waves. i  In news reports & articles written for the general public EMF is used loosely to indicate the low frequency electromagnetic fields coming from power lines, home wiring, appliances, TVs & computer displays. i  Electric power lines produce low frequency fields & appliances operating at a frequency of 60 Hz.Low-frequency energy is forms of non-ionizing radiation. i  This chamber was set-up to be a thin terrarium like environment that would allow observation of the continued progress of the root system with the electromagnetic waves being produced from a low powered device. An electronic device that has been know to create low frequency EMFs, in this case an electric train transformer, was placed on a timer to submit the plants to a 5 hour period of radiation on daily intervals. i

Computer Monitors, Radiation & You

 i  Studies are conflicting, but some research has identified potential health hazards from long-term exposure to non-ionizing electromagnetic radiation in the low frequency (ELF) & low frequency (VLF) range. VDTs, like television sets, give off non-ionizing electromagnetic radiation, which is composed of electric (...) & magnetic (...) fields. i  OCLI sponsored a 1994 Electric Field Shielding Effectiveness Test to determine how well OCLI GlareGuard filters block E-field radiation. Testing shows that the GlareGuard® Maximum +ª filter blocks up to 99.9% of the ELF/VLF electric field radiation, while the GlareGuard® Maximum filter blocks up to 99% of the ELF/VLF E-field radiation. Magnetic Field Shielding Effectiveness of Anti-Radiation/Anti-Glare Filters As of the questions surrounding VDT magnetic radiation & anti-radiation filters, OCLI sponsored a 1990 "Magnetic Field Shielding Effectiveness" study. i  The testing indicates that anti-radiation screens do NOT block magnetic fields at the ELF/VLF levels. Changes must be made within the computer monitor itself to reduce low frequency magnetic radiation. "None of the anti-glare/anti-radiation screens tested show any sign of magnetic field attenuation in the major frequency range of concern, that is, the low frequency range of 30Hz to 30kHz," reported Daryl Gerke of Kimmel Gerke Associates, .  i   i

Electromagnetic Waves: How Real a Hazard?

 i  excerpts from the “Harvard Medical School Health Letter”   The term “electromagnetic field” applies to a type of energy that is beamed through the air. i  Both types of electromagnetic radiation can kick electrons out of their normal orbits & thus are called ionizing. Nobody thinks that low-frequency fields from power lines or appliances produce such drastic damage; they are nonionizing & simply aren’t energetic enough.   At sufficiently high frequency, electromagnetic radiation agitates water molecules, thereby generating heat. i  But these fields fall to low levels a few inches away from the motor, & as smaller appliances tend to be used only briefly, they aren't believed to contribute much to the total human exposure to 60-hertz fields.   Dr. Tenforde, who is now the Chief Scientist of the Life Sciences Center at Battelle Pacific Northwest Labs, also points out that these effects are sometimes seen at lower field strengths rather than higher ones. i  One explanation consistent with the existing data is that, if tissues respond at all to low-frequency fields, they respond only to quite narrow bands of frequency & field strength.   Home Newsletter Clustered Water Optimal Health Products Bio Photanical products Health Reports Total Body Modification Visit the Office Sound Therapy Qualified Leads Postcards Malls

 i  Few data are available on the risk associated with low-dose exposure, the effects of different types of radiation &, in particular, the risks associated with the prolonged exposure of concern for the general population. i  Non-Ionizing radiations include those radiations & fields which don't have enough energy to cause ionization in tissues, but which may cause adverse health consequences in other ways, e. i  Although solar UV radiation has been established as a human carcinogen (IARC Monographs, Volume 55: Solar & Ultraviolet Radiation), the evidence for other parts of the electromagnetic fields (EMF) spectrum (in particular radiofrequency radiation emitted by mobile telephones & low frequency fields emitted by electricity transmission lines & electrical appliances)..   i 
The programme studies the carcinogenic effects of radiations, in particular, low doses of ionizing radiation, in relation to the type of radiation, patterns of exposure, & host & environmental factors. The aim of this work is twofold: to strengthen the scientific bases of radiation protection (...), & to increase our understanding of biological mechanisms of carcinogenesis.

Radiofrequency and Microwave Radiation in the Workplace-Ontario Ministry of Labour

 i  As well, the lower-frequency boundary of RF radiation is often extended to 10 kHz, or even to 3 kHz, in order to include emissions from commonly used devices.
The frequency of electromagnetic fields is measured in Hz (hertz), or cycles per 2nd.
 i  This guideline gives advice on preventing overexposure to RF/MW radiation in the workplace & sets out Occupational Exposure Limits which are enforced in Ontario workplaces by the Ministry of Labour under the general duty clause (section 25(2)(h) of the Occupational Health & Safety Act ). i  The nature & the degree of the health effects of overexposure to RF/MW fields depend on the frequency & intensity of the fields, the duration of exposure, the distance from the source, any shielding that may be used, & other factors. i  Some lab studies have reported biological effects from RF/MW radiation at field levels which are too low to cause tissue heating. i  Although we are constantly exposed to weak RF fields from radio & television broadcasting, no health risks have been identified from this low-level exposure. i  Since the RF/MW energy absorbed by the body varies with the frequency of the fields & since the rate of energy absorption is difficult to measure directly, the exposure limits are expressed in terms of frequency-dependent, root-mean-square (RMS) electric & magnetic field strengths, or in power density units (...). i  This can be achieved by reducing stray fields & installing appropriate insulation & grounding, or by ensuring that the electric current flowing between a worker & an object energized by electromagnetic fields doesn't exceed the values in Table II. i

  • Some nonionizing radiation can interfere with the operation of heart pacemakers & other medical devices, as well as critical equipment in aircraft.
  • High levels of radio frequency & microwave radiation can heat tissue & if the temperature increase is high enough, can adversely affect health.
 i  low-frequency electric & magnetic fields (EMFs) surround electrical machinery, home appliances, electric wiring, & high-voltage electrical transmission lines & transformers. i  Alternating-current (AC) electricity, with a frequency of 60 cycles per 2nd, falls into the low frequency range on the electromagnetic spectrum (Figure 1) & thus has far too little energy to cause ionization.   i  A majority of the panel found "limited evidence that residential exposure to low frequency magnetic fields may increase the risk of childhood leukemia." i  The NIEHS did conclude, however, in its 1999 Report to Congress, that-low-frequency EMF exposure cannot be recognized as entirely safe as of weak scientific evidence that exposure may pose a leukemia hazard; the associations reported for childhood leukemia & adult chronic lymphocytic leukemia cannot be dismissed easily as random or negative findings.   i  As hand-held cellular telephones become increasingly popular, people are understandably concerned about potential health effects from exposure to high-frequency radio waves. The radio waves used by analog & digital cellular phones are much higher frequency than the electric & magnetic fields produced by power lines, so their biological effects are different from the possible effects of EMFs.   i

Scientific American Article:

Medicine What is the current understanding regarding the health effects of low-frequency electromagnetic radiation, eg ?  that from high-voltage power transmission lines? "There have been hundreds of studies of the health implications of exposure to low-frequency electromagnetic fields. A committee of the National Academy of Sciences recently reviewed this literature & concluded that there is no consistent & convincing evidence of adverse health effects from residential exposures. But the positive ones havn't been replicated, & no consistent picture of health risk emerges. "One of the most difficult areas to study is the possible relation between childhood leukemia & exposure to electromagnetic fields (EMFs), which has turned up in a number of epidemiological studies (...). The problem is that these same studies found no association between the measured strength of EMFs & the leukemia incidence. In other words, living near power lines seems to be associated with leukemia, but the measured field strength is not.

Computer Use-- Radiation Issues

 i  Lower energy electromagnetic radiation is referred to as non-ionizing radiation. i  Man-made sources of ionizing electromagnetic radiation include X-rays from medical & radiographic equipment, therapeutic & diagnostic radiochemicals, & nuclear power. i  Low Frequency [VLF] & Low Frequency [ELF] : Circuits within the monitor are responsible for the horizontal (...) & vertical (...) movement of the electron beam. i  The MIT Radiation Protection Office (RPO) has measured electromagnetic field intensities from representative models of several manufacturers of monitors in use at MIT. Computer monitor users have expressed concerns about the possible health effects from the electromagnetic radiation that monitors produce. i  Current available scientific information doesn't identify a health risk from exposure to the electromagnetic fields associated with the use of computer monitors.    i  Although the electromagnetic radiation field intensities are measurable, they aren't substantially above background office levels. i  The present consensus of experts is that there are no data to suggest a health risk from exposure to the electromagnetic fields associated with the use of monitors. i
