Health Limits
Before You Begin
Within the United States, environmental guidelines regulating safe exposure levels are
issued by the Occupational Safety and health Administration (OSHA).
Section 1910.97 of OSHA Safety and Health Standards 2206 legislates a maximum
safe exposure limit of 10 milliwatts per square centimeter (mW/cm
minutes at both 915 and 2450 MHz.
Although not binding, other organizations such as the American National Standards
Institute (ANSI) have issued similar guidelines that are more restrictive than the
OSHA limits (ANSI C95.1). ANSI guidelines recommend a maximum safe power
2
density in mW/cm
of:
2 ) averaged over 6
Frequency
-------------------------------------------------------
Thus, the maximum permissible exposure for general population/uncontrolled
exposure at 915 MHz is 0.61 mW/cm2. The power limit is a 6-minute average.
The RF power density generated by Amtech® equipment was calculated using a maximum antenna gain of 14 dBi that is equivalent to that typically used in an AR2200
installation.
The antenna gain should not exceed 14 dBi. The antennas used for this transmitter
must not be collocated or operated in conjunction with any other antenna or transmitter.
At 1.6 W transmitted power and a distance of 22 inches (55 cm) from the antenna, the
maximum power density calculated was 0.6 mW/cm2. Install the antennas at least 22
inches (55 cm) from the general public. Maintenance personnel must remain at least
9.7 inches (24.5 cm) from antennas when system is operating.
The data confirms that the Amtech® system effectively meets OSHA requirements
and thus does not represent an operating hazard to either the general public or maintenance personnel.
