 Cordless Phones
Cordless phones also use radiofrequency radiation to transmit  signals  According to the Bioinitiative Report of 2007, a 600+ page report written by a team of 14 scientists throughout the world, use of cordless phones predominantly on the same side of the head for more than 10 years increases people's risk of a malignant glioma (brain tumor) by 470%.  If a cordless phone is used on both sides of the head for more than ten years, your risk of a malignant glioma is 220% higher.
The base station of the most recent digitally enhanced cordless technology (DECT) cordless phones constantly emits radiofrequency radiation.  Although cordless phones have been used in homes for decades, those cordless phones radiated only when you were on the phone.  In the past few years, cordless phones for sale in stores became digital and constantly radiate. Basically all cordless telephones sold in the US use the 900 MHz, 1.9 GHz, 2.4-GHz, or 5.8 GHz bands.  In October 2005, the 1.9 GHz frequency band was allocated in the United States and is now used by the popular DECT cordless phones. The 1.9 GHz band is considered more secure than the other shared frequencies.  Today’s cordless phones operate in a higher frequency band and expose us longer to radiofrequency radiation than in earlier decades. 
Placing an electrosmog detector (which turns levels of radiofrequency radiation into sound) near the base of a 6.0 DECT phone, causes the electrosmog detector to sound like an alarm.  View a demonstration in our video vault.

Dr. Magda Havas of Trent University, created a 7 minute video that demonstrates radiation from a cordless (DECT) phone can interfere with the heart.  It also shows that non-thermal exposure, at levels well below federal guidelines in most countries (0.3% of the 1000 microW/cm2), has biological and health effects.   

Another 2.5 minute video by Dr. Havas demonstrates the effect on blood before and after using a computer and cordless phone.
