  • My initial interest was directed to the possible etiologic effects of emf fields. (rife.org)
  • Reproductive toxicity has been defined as the occurrence of adverse effects on the reproductive system that may result from exposure to environmental agents. (iloencyclopaedia.org)

  • Our discussion will not include the effects of postnatal exposures on development. (iloencyclopaedia.org)

  • reproductive
  • In addition to reproductive toxicity, exposure to either parent prior to conception has the potential of resulting in developmental defects through mutagenesis, changes in the genetic material that is passed from parent to offspring. (iloencyclopaedia.org)
  • weaker
  • Modern flat screens do not have tubes and due to their design and operating mode they do not emit X-rays, and, moreover, their magnetic fields are considerably weaker than those of tube screens. (bfs.de)
  • cancers
  • Most cancers are related to environmental, lifestyle, or behavioral exposures. (wikipedia.org)
  • Millions of workers run the risk of developing cancers such as lung cancer and mesothelioma from inhaling asbestos fibers and tobacco smoke, or leukemia from exposure to benzene at their workplaces. (wikipedia.org)
  • currents
  • Exposure to electromagnetic fields , contact currents and induced currents through the limbs are treated separately. (emf-portal.org)
  • For this reason, in addition to the field strengths shown in the " Reference levels " table, a limit for currents through the limbs is defined in the BGV B11. (emf-portal.org)
  • Energy from RF currents in conductors can radiate into space as electromagnetic waves (radio waves). (wikipedia.org)
  • The induction of currents by oscillating magnetic fields is also the way in which solar storms disrupt the operation of electrical and electronic systems, causing damage to and even the explosion of power distribution transformers, blackouts (as occurred in 1989), and interference with electromagnetic signals (e.g. radio, TV, and telephone signals). (wikipedia.org)
  • electric
  • Studies concerning specific sources of exposure relative to fetal development and pregnancy outcome have included the use of electric blankets, heated waterbeds, power lines, video display terminals, and other occupational sources. (bmj.com)
  • Requirements related to emissions of electric and magnetic fields are contained in DIN regulations. (bfs.de)
  • Strong electric fields (from high voltages applied to small or pointed conductors) often produce violet-colored corona discharges in air, as well as visible sparks. (wikipedia.org)
  • waves
  • Also, the study authors acknowledged that since the research was not an experiment or a controlled trial, it does not establish a direct cause-and-effect relationship between electromagnetic waves and ALS, only a potential association. (hon.ch)
  • risk
  • Workplace exposure to electromagnetic fields is linked to a higher risk of developing the most common form of motor neurone disease. (stopumts.nl)
  • Results: The total risk of birth defects was not associated with parental exposure. (bmj.com)
  • The other occupational factors assessed were only weakly associated with ALS risk in both men and women, and there was no clear evidence of a linear increase in risk according to the amount of cumulative exposure. (bmj.com)
  • Other occupational factors were only weakly associated with ALS risk, and the researchers found no clear evidence that risk increased with higher levels of exposure. (hon.ch)
  • This study showed that electromagnetic fields could contribute to the 39 percent of risk attributable to as-yet-unknown environmental factors, he said. (hon.ch)
  • Occupational exposure to textile dust is associated with a more than doubling in the risk of developing rheumatoid arthritis, finds research published online in the Annals of the Rheumatic Diseases. (medicalxpress.com)
  • Applications of the PIMEX methods are various, focusing on work task analysis, training and risk communication, encouraging worker participation in and motivation for improvements in the workplace environment. (wikipedia.org)
  • It is a widely used in the Netherlands for risk communication in the field of chemical exposure and it has been proven to be a very strong communication tool. (wikipedia.org)
  • The primary risk factor for erethism is long-term exposure to mercury vapors and gasses at high levels. (wikipedia.org)
  • cumulative exposure
  • Furthermore, those in the top 30% of cumulative exposure (duration x intensity) were nearly twice as likely to develop the disease. (bmj.com)
  • People with the most cumulative exposure -- long periods combined with high intensity -- were nearly twice as likely to develop ALS. (hon.ch)
  • Vermeulen
  • This doesn't mean that folks should worry about exposure from using household appliances, Vermeulen said. (hon.ch)
  • regulations
  • At workplaces, special regulations apply. (emf-portal.org)
  • Employers Liability Insurance Associations have worked out accident and injury prevention regulations (abbreviated UVV for Unfallverh tungsvorschriften, Germany) for electromagnetic fields, referenced as BGV/BGR B11. (imst.com)
  • These regulations are designed to prevent occupational injuries to employees, but they also offer liability protection for employers who observe these rules. (imst.com)
  • Up to today, occupational regulations related to work with display screen equipment have been established solely for ergonomic reasons. (bfs.de)
  • sunlight
  • In this sense, the environment is not limited to the biophysical environment (e.g. exposure to factors such as air pollution or sunlight, encountered outdoors or indoors, at home or in the workplace), but also includes lifestyle, economic and behavioral factors. (wikipedia.org)
  • observational
  • The team have stressed that this study is observational - it has not proven that the fields themselves cause ALS, just that this factor is linked to a person's likelihood of developing the disease. (stopumts.nl)
  • mandatory
  • When carrying out work in this hazardous area, the wearing of personal protective equipment is mandatory and thus precludes impermissible exposures . (emf-portal.org)
  • SEARCH
  • Methods: First, a comprehensive literature search was performed for published and unpublished documents containing exposure measurements for the EMF sources identified, a priori as well as from answers of study subjects. (oregonstate.edu)
  • analysis
  • Lomen-Hoerth said it's too early to discount those other possible workplace exposures, since the analysis included so few people who died from ALS. (hon.ch)
  • Visualization of a good practice method In the Netherlands, the method is available to small and medium enterprises by the use of a half day workplace analysis or simple videos can be made. (wikipedia.org)
  • duration
  • The problem with mercury is that if humans are exposed to any of the forms of mercury, depending on the amount (dose), route (ingestion, skin contact, inhalation), duration (time) of exposure, it can be toxic. (wikipedia.org)
  • strengths
  • Rather than establishing an etiologic pathway between emf and cancer we found that the application of these fields in strengths comparable to what could be considered reasonably to be within range of environmental exposure to suppress the growth of cancer cells as well as their ability to invade as measured in standard invasion chambers. (rife.org)
  • scientific
  • The IOM was set up by Dr John Rogan, the Chief Medical Officer of the NCB, who had initiated the Pneumoconiosis Field Research (PFR), persuaded the then Chairman, Lord Robens, to found a scientific institute to take over the running of this research. (wikipedia.org)
