Electro Magnetic Fields Overview

-EMF-

What is EMF?

Electro Magnetic Fields (EMF) emissions are created whenever electrical power flows through a wire, conductor or appliance; they can not be seen, felt or heard, but they are present in and around all electric lines and devices. EMF emissions are measured in units called milliGauss(mG). Thestrength of the EMF can vary and is measurable by use of this K-ll EMF Meter.

Why Measure EMF?

EMF emissions are recognized as an environmental agent that are a potential threat to public health. Some scientific evidence suggests links of the biological effects of EMF to childhood leukemia, brain cancer, miscarriages and fetal abnormalities. We are exposed to EMF at home, in the workplace and even outdoors everyday.

What Levels are Safe?

Many studies have determined that the relationship between field strength and health risks also involves other factors which make it impossible to assign exact danger level limits based only on field strength.

Though the US government has not yet provided exact danger level limits, other countries and many states have already set standards for exposure based on field strengths. In general a target of 2 to 3 milliGauss is believed to be a reasonable maximum level for continuous exposure.

The EMF METER measures magnetic field strength. GREEN LED's indicates normal everyday levels of exposure, the higher more suspect field strength readings are indicated by the YELLOW, ORANGE and RED LED displays

What can we do about it?

The easiest thing is to try to reduce your exposure to the fields by practicing "prudent avoidance". Measure all of the electrical appliances and devices at home, at work and when you travel, noting the results on the attached Exposure Log. Then try to avoid the YELLOW / ORANGE / RED range readings by staying far enough away from the appliance to remain in theGREENrange. Rearranging your furniture or appliances, or by using timers on some appliances to reduce exposure when operating can also be effective in reducing your exposure.

Continue to check field sources around and in your home, as well as in the schools or your workplace on a routine basis since fields may change (ie: appliances may change due to age or pending failure). Use the EMF METER when you travel, are looking at real estate or when shopping for new appliances.

DESCRIPTION

The EMF Meter is a compact and easy to use Magnetic Field strength meter. The EMF Meter can be used indoors or outdoors for measuring any electric device or power lines. There are 5 LED's, each represents a field strength range as follows:

OPERATION

1) Hold the EMF METER with your thumb on the switch

2) Point it toward the EMF source, then depress and hold down the switch (a short flash of the

  LED's will occur)

3) The LED will indicate the range of the EMF at that level

4) Moving the device from side to side or rotating it may change the reading; the highest reading is most accurate

5) Move closer or further away to the EMF source to determine the "Normal" zone, as indicated by the Green LED

Helptul Hints:

- Record the readings on the enclosed Exposure Log, repeat periodically, since fields can change in strength

- If the GREEN LED (Normal) doesn't light, the battery is low

- To change battery remove the two screws, replace 9V battery
