Radiation from cordless phones

When cordless phones first came out they were pretty harmless, they were analog models. Some of the early ones worked on frequencies of 40/50 megaHz with power outputs in the 5-25 milliwatt range. These were emitting  signals at fairly low frequency. Soon these were replaced by digital versions which operate broadly in 800/900 megaHz range but they are equipped with Digital spread spectrum (DSS) technology for better performance. This results in  higher frequencies and higher power outputs.

Few years later they digital enhanced cordless phones (DECTs) was introduced which operate at 2.4 GHz – frequency at which a microwave oven “cooks” food. These new cordless phones operate on frequencies of  up to 5800 megaHz with power outputs up to 250 milliwatts.

How To Reduce Your Exposure

  1. Throw cordless phone out and use a wired phone.
  2. Put cordless phone base station at least 6 feet away from where you.
  3. Keep your calls short.
  4. Plug your cordless phone only when you use it. Once charged these modern day DECTs work for at least 4/5 days.
  5. Unplug your cordless phone at night.
  6. Like cell phone use the speakerphone and keep the phone away from your head as much as possible.
