  2. Personal RF safety monitor - Wikipedia

    en.wikipedia.org/wiki/Personal_RF_safety_monitor

    Usually, the alarm of most RF personal monitors is triggered by instant values, however, standard limits are specified as time-averaged values. Some RF monitors have the possibility to trigger alarms based on average values, which is a better indication of the real exposure situation (as an example, an instant value can be at 200% while the ...

  3. High-intensity radiated field - Wikipedia

    en.wikipedia.org/wiki/High-intensity_radiated_field

    An RF electromagnetic wave has both an electric and a magnetic component (electric field and magnetic field), and it is often convenient to express the intensity of the RF environment at a given location in terms of units specific to each component. For example, the unit "volts per meter" (V/m) is used to express the strength of the electric ...

  4. Specific absorption rate - Wikipedia

    en.wikipedia.org/wiki/Specific_absorption_rate

    In comparison to the short term, relatively intensive exposures described above, for long-term environmental exposure of the general public there is a limit of 0.08 W/kg averaged over the whole body. [2] A whole-body average SAR of 0.4 W/kg has been chosen as the restriction that provides adequate protection for occupational exposure.

    The FCC limits for maximum permissible workplace exposure to shortwave radio frequency energy in the range of 3–30 MHz has a plane-wave equivalent power density of (900/ f ‍ 2) mW/cm 2 where f is the frequency in MHz, and 100 mW/cm 2 from 0.3 to 3.0 MHz.

  6. Radio spectrum - Wikipedia

    en.wikipedia.org/wiki/Radio_spectrum

    A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.

  7. Wireless device radiation and health - Wikipedia

    The HPA also says that due to the mobile phone's adaptive power ability, a DECT cordless phone's radiation could actually exceed the radiation of a mobile phone. The HPA explains that while the DECT cordless phone's radiation has an average output power of 10 mW, it is actually in the form of 100 bursts per second of 250 mW, a strength comparable to some mobile phones.

    The public exposure limit is 1 mSv in a year. [11] Emergency exposurelimits given for occupational and public exposure; Existing exposure – reference levels for all persons exposed; The public information dose chart of the USA Department of Energy, shown here on the right, applies to USA regulation, which is based on ICRP recommendations.

  9. Occupational exposure limit - Wikipedia

    en.wikipedia.org/wiki/Occupational_exposure_limit

    An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by competent national authorities and enforced by legislation to protect occupational safety and health .
