  3. ម៉ារី ថា:

    Current researches show that cellular radio radiation doesn’t pose any health threats. Network as well as electronic equipment is made by conforming to safety requirements. Manufacturers already set the limit for maximum radio radiation to meet the requirements.

    You can find more information at:

    http://www.fcc.gov/oet/rfsafety/cellpcs.html
    http://www.fcc.gov/cgb/cellular.html

    In conclusion, there is no worry.

    They know the radio radiating from the base station antenna.
    Mobile phone system (2G-3G) operate at the frequency from 800Mhz-2100Mhz, which is called non-ionizing radiation. It doesn’t cause any harmful effect on human health. Please also refer to the links.

    From FCC, US:
    “In the case of cellular base station transmitters, at a frequency of 869 MHz (the lowest frequency used), the FCC’s RF exposure guidelines recommend a maximum permissible exposure level of the general public (or exposure in “uncontrolled” environments) of about 580 microwatts per square centimeter (µW/cm2), as averaged over any thirty-minute period. This limit is many times greater than RF levels typical found near the base of typical cellular towers or in the vicinity of other, lower-powered cellular base station transmitters. For example, measurement data obtained from various sources have consistently indicated that “worst-case” ground-level power densities near typical cellular towers are on the order of 1 µW/cm2 or less (usually significantly less). Calculations corresponding to a “worst-case” situation (all transmitters operating simultaneously and continuously at the maximum licensed power) show that in order to be exposed to levels near the FCC’s limits for cellular frequencies, an individual would essentially have to remain in the main transmitting beam (at the height of the antenna) and within a few feet from the antenna. This makes it extremely unlikely that a member of the general public could be exposed to RF levels in excess of these guidelines from cellular base station transmitters.”

    http://www.fcc.gov/oet/rfsafety/cellpcs.html

    From ARPNSA, Australia:
    “The exposure levels of RF radiation are measured in microwatts per square centimeter (abbreviated as μW/cm2). One μW is a millionth of a watt. The maximum exposure levels measured adjacent to the base station towers are less than 2 μW/cm2. The exposure level decreases with increasing distance from the base of the tower.

    These levels can be compared with 450 μW/cm2, which is the exposure limit at 900MHz for members of the public (that is, unlimited exposure duration)”
    http://www.arpansa.gov.au/RadiationProtection/Factsheets/is_antenna.cfm

    From MIC, Japan:

    “The radio waves currently used for telecommunication or broadcasting are electromagnetic waves (non-ionizing radiation) which do not have enough energy to ionize atoms from materials. Although some of the electromagnetic waves, such as ionizing radiation including X-ray or gamma-ray, have high frequencies and strong energy that ionize atoms, they are very different from the radio waves we are dealing with; that is non-ionizing radiation.”

  7. ម៉ារី ថា:

    Although there is no published report on the exposure level of mobile base station antennas in Cambodia, it is very unlikely that it would exceed the allowed level specified by various countries when all operators are deploying the standardized cellular systems developed by recognized industries.

    For example, the allowed max transmitted power for Wireless LAN system is no greater than 1watt. Although engineers want to increase it more than this, it is still impossible because products from Avarion for instance won’t allow this.

    Cellular systems need more careful power control specified in its standards adopted by all manufacturers to have optimum communications.

    In short, engineers can’t do anything more than the given max values of equipments from manufactures, which are supposed to conform to international standards and safety requirements specified by WHO and organizations concerned.
