  • threshold

  • Based upon a criterion modeled suppression level of 5% for a "cool white" light (6500 K), a corneal light exposure of 30 lux for 30 minutes from "white" light sources used in most architectural lighting applications is proposed as a conservative hypothesized working threshold for nocturnal melatonin suppression.

  • Once you know your required APF, you can narrow down your choices to those respirators that can reduce exposure to below the OEL. (3m.com)
  • The health threat from radon can be addressed by identifying geographic areas that could produce elevated levels of indoor radon, developing strategies to reduce exposure, conducting research on effective remedial measures to be taken in buildings, and providing educational programs for health officials and the public. (cdc.gov)
  • Changes in usage patterns of high-radon areas in a home, such as the basement, and the control of future construction in geographic areas high in uranium deposits can reduce exposure. (cdc.gov)
  • lung
  • Therefore, the exact causative agent of lung disease from airborne exposure to food flavorings remains unknown until further research can demonstrate conclusive findings. (ohsonline.com)

  • investigate
  • The objectives of this study were to investigate the pollution level of PM 10 -bounded PAHs in summer in a new urban area of Nanjing, the main sources of PAHs in PM 10 , and the ILCR caused by particulate PAHs for local population groups of different age and gender. (hindawi.com)
  • requires
  • Specifically, the Federal Communications Commission (FCC) in the United States requires that phones sold have a SAR level at or below 1.6 watts per kilogram (W/kg) taken over the volume containing a mass of one gram of tissue that is absorbing the most signal. (westonaprice.org)
  • Requires exposure monitoring for students and teachers when working with hazardous materials, especially formaldehyde-based products. (isd742.org)
  • employers
  • Most employers can limit harmful dust exposure by using equipment that is widely available - generally using water to keep dust from getting into the air or a ventilation system to capture dust where it is created. (dol.gov)
  • Affect
  • Exposure to bright electric lighting at night or dim electric lighting during the daytime, however, can affect the timing of SCN and, thus, circadian rhythms. (omicsonline.org)
  • found
  • Defenders of Wildlife found the highest levels of mercury in tuna from Ecuador and Mexico -- countries known for setting nets where dolphins are seen to catch large tuna swimming below. (enn.com)
  • The lab found higher levels of mercury even in light tuna, which the Food and Drug Administration considers to be low in mercury. (enn.com)
  • Particle levels found in the test zone can be compared to those in a control zone. (slideserve.com)
  • This research has found effects at every level of organization of life, from the behavior and performance of humans and animals down to the molecular and genetic levels. (westonaprice.org)
  • These findings were confirmed in 2012 when Arnie Gundersen analysed five random soil samples from Tokyo sidewalks, parks and playgrounds - and found levels of contamination up to 7,000 Bq/kg. (willthomasonline.net)
  • determine
  • It was not possible to determine whether any of the reported medical problems resulted from exposure to ELF. (cdc.gov)
  • Step Three: Determine level of protection needed. (3m.com)
  • below
  • If your employee exposure levels are below the OEL, then respirators aren't legally required, though you may still want to offer respirators for voluntary use. (3m.com)
  • light
  • Defenders of Wildlife said people should limit light tuna to one meal each week, instead of two, and avoid canned tuna that says it is imported from Latin America on the label. (enn.com)
  • Retinal light exposures can decrease melatonin production at night. (omicsonline.org)
  • One blood sample was drawn in dim light at midnight and another blood sample was drawn after 60-minute exposure to each light condition (including dark). (omicsonline.org)
  • Since the biophysical characteristics of light affecting our visual system are markedly different than those affecting our circadian system, exposure to electric lighting, day and night, may disrupt the natural 24-hour circadian cycle. (omicsonline.org)
  • To estimate which light exposures throughout the solar day are and are not effective for stimulating the circadian system, it is necessary to characterize the spectral and absolute sensitivities of the human circadian system to retinal light exposures. (omicsonline.org)

  • As noted by Klinghardt, "Unfortunately, the membranes around the womb have that strange effect in significantly concentrating the ambient EMFs that the mother is in, reaching levels that are not sustainable for human development. (mercola.com)
