Electromagnetic Field Safety Meters

From Orbis these products are only available in Finland.

Personal safety is something we are all concerned about, including RF and electromagnetic fields and their effects on safety. There are more and more devices communicating by RF and their use has exploded.

Electromagnetic field is a challenge due to its nature: one can not feel, taste, smell or hear it. We as humans simply do not sense it (at least not until real tissue damage). The most dangerous frequency area to humans is between 30-300 MHz.

German based company NARDA Safety Test Solutions is a global leader in the development and production of measuring equipment for electric, magnetic, and electromagnetic fields, owning more than 95% of all published patents for measuring such fields. Narda safety products are designed for professional use.

Personal safety monitors are Nardalert and RadMan.


Electric field

  • E = Field strength
  • Unit = V / m

Magnetic Field

  • H = Field strength
  • A/m = unit (RF,HF)

Magnetic flux

  • B = field density
  • Tesla = unit (low frequency)

Typical SAR values (RF)

  • Limit value 10
  • ICNIRP field strength limit (for personnel) 0,4 W/kg
  • Limit value 5
  • ICNIRP field strength limit (public places) 0,08 W/kg

Effects of Radiation

Instant effects

  • Warming
  • Reflexes
  • Pacemaker dysfunction
  • Lens of Eye clouds
  • These are basis for most limits e.g. ICNIRP

Long-term effects

  • Immune system is weakened
  • Changes in hormone balance and psyche
  • Risk of cancer
  • Increase in cell growth
