About Cordless Phones (DECT) EMF

  • -That cordless phone sitting in your kitchen or living room may seem like a harmless relic from the pre-smartphone era, but it's actually one of the most potent sources of radiofrequency (RF) radiation in your home.
  • -DECT phones (Digital Enhanced Cordless Telecommunications) operate at 1.9 GHz, continuously transmitting RF signals between the handset and base station even when you're not making calls.
  • -Think of it like having a mini cell tower running 24/7 in your house, except this one sits just inches from your head during conversations and often much closer to your body throughout the day.

Effect on the immune system of mice exposed chronically to 50 Hz amplitude-modulated 2.45 GHz microwaves.

Elekes, E, Thuroczy, G, Szabo, LD · 1996

Researchers exposed male and female mice to microwave radiation at 2.45 GHz (similar to microwave ovens and WiFi) for 3 hours daily over 6 days to test effects on immune function. They found that both continuous and pulsed microwave exposure significantly increased antibody production in male mice (37-55% increases), but had no effect on female mice. This suggests that microwave radiation can stimulate immune system activity, with males appearing more sensitive than females.

Effect of continuous-wave and amplitude-modulated 2.45 GHz microwave radiation on the liver and brain aminoacyl-transfer RNA synthetases of in utero exposed mice.

Kubinyi G, Thuroczy G, Bakos J, Boloni E, Sinay H, Szabo LD, · 1996

Pregnant CFLP mice were exposed to 2.45 GHz microwave radiation for 100 minutes each day throughout gestation in an anechoic chamber. Brain aminoacyl-tRNA synthetase activity decreased significantly after continuous-wave exposure but not after amplitude-modulated exposure. Liver enzyme activity increased after both continuous-wave and amplitude-modulated exposure, while body and organ weights were unaffected.

Modification of lethal radiation injury in mice by postradiation exposure to low-intensity centimeter-band radio frequency waves

Akoev IG, Mel'nikov VM, Usachev AV, Kozhokaru AF, · 1994

Researchers studied whether exposure to low-intensity radiofrequency radiation after a lethal dose of gamma-radiation could modify the resulting injury in mice. The radiofrequency exposure lasted up to 23 hours at an intensity of 5 plus or minus 1.5 microwatts per square centimeter, covering frequency ranges of 2-8, 8-18, and 19-27 GHz with a swing frequency of 12-14 Hz. A clearly pronounced modification of acute radiation injury was obtained when the radiofrequency exposure was applied immediately after the gamma-radiation.

Immune SystemNo Effects Found

Antibody responses of mice exposed to low-power microwaves under combined, pulse-and-amplitude modulation.

Veyret B et al. · 1991

French researchers exposed mice to low-power pulsed microwaves (similar to radar frequencies) for 10 hours daily over five days to test effects on immune system function. They found that simple pulsed signals had little effect, but when the signals included additional amplitude modulation, the mice showed significant changes in antibody production - some frequencies strengthened immune responses while others weakened them.

DNA & Genetic DamageNo Effects Found

A chromosomal study of workers with long-term exposure to radio-frequency radiation.

Garson OM, McRobert TL, Campbell LJ, Hocking BA, Gordon I. · 1991

Researchers studied chromosome damage in 38 radio-linemen exposed to radio-frequency radiation and 38 matched controls. They analyzed Two hundred metaphases per person, scored blind, and found the rate of aberrant cells was the same in both groups. There were no statistically significant differences in the types of chromosome aberrations.

Neoplastic transformation of C3H/10T1/2 cells following exposure to 120-Hz modulated 2.45-GHz microwaves and phorbol ester tumor promoter.

Balcer-Kubiczek EK, Harrison GH. · 1991

Researchers exposed actively growing cultures of C3H/10T1/2 cells for 24 hours to 2.45-GHz microwaves pulse-modulated at 120 Hz. The electromagnetic fields alone had no effect on cell survival or induction of neoplastic transformation. When combined with the tumor promoter TPA, the enhancement of transformation was highly significant and ranged up to a level equivalent to that produced by 1.5 Gy of X rays. The frequency of neoplastic transformation was dependent on the level of electromagnetic exposure and was additive with doses of X rays given as a cocarcinogen.

Reduced exposure to microwave radiation by rats: frequency specific effects.

D'Andrea JA, DeWitt JR, Portuguez LM, Gandhi OP. · 1988

Two experiments tested whether frequency-specific hotspot formation in the body and tail of rats would have behavioral consequences. Rats were placed in a cage where occupying one side triggered microwave exposure and occupying the other side ended it. Reduced exposure to 360-MHz and 2450-MHz microwaves at 1, 2, 6 and 10 W/kg were significantly different from 700-MHz microwaves. A second experiment found the threshold for reduced exposure to 2450-MHz microwaves fell between whole-body SARs of 2.1 and 2.8 W/kg.

Federal Radiation Protection Guidance; Proposed Alternatives for Controlling Public Exposure to Radiofrequency Radiation; Notice of Proposed Recommendations

Unknown authors · 1986

The EPA proposed four alternative approaches to limit public exposure to radiofrequency radiation. Three options are regulatory and would set whole-body average SAR limits of 0.04, 0.08, and 0.4 W/kg for frequencies above 3 MHz. For frequencies below 3 MHz, the regulatory options would limit electric field intensity to 87, 275, and 614 V/m and magnetic field intensity to 0.23, 0.73, and -1.63 A/m respectively. The fourth option is nonregulatory and would use information and technical assistance programs instead of adopting Federal Guidance.

WEST GERMANY PUBLISHES EMF EXPOSURE STANDARD

Thomas C. Rozzell · 1984

The article reports that West Germany published its first official human-exposure guidelines for electromagnetic fields, applicable to both workers and the general public. The German standard covers frequencies from 0.01 MHz to 3900 GHz, which is wider than the ANSI standard’s 0.1 MHz to 100 GHz range.

Environmental Health Criteria 16: Radiofrequency and Microwaves

Sol M. Michaelson · 1982

The review evaluates the World Health Organization's Environmental Health Criteria 16 document on radiofrequency and microwave fields from 100 kHz to 300 GHz. The reviewer finds the publication unbalanced because it accepts nonthermal interaction literature with cursory critique while neglecting refuting evidence. The review notes that the document's designations of high, medium, and low power densities are ambiguous and ignore the frequency dependence of bioeffects. It points out specific errors in Table 10 frequency designations and an incomplete discussion of chronic cataract studies that omitted rabbit and monkey data showing no ocular damage. The reviewer concludes the document does not meet the high scientific caliber and accuracy of usual WHO publications.

Radio-Frequency and Microwave Radiation

Howard Bassen · 1980

This 1980 FDA research by H. Bassen examined radio-frequency and microwave radiation exposure measurement and safety standards. The study focused on how these electromagnetic fields are absorbed by human tissue and established methods for assessing exposure levels. This represents early foundational work in understanding RF/microwave radiation effects on human health.

A Study To Investigate Federal Regulation of Microwave Standards

Leonard David · 1980

The study outlines the historical background of U.S. microwave exposure guidelines and identifies the lead federal agencies. No federal standards exist to protect workers or the public, only a voluntary 10 mW/cm² guideline from 1966. Regulatory trends point toward more stringent occupational and public exposure limits, possibly as low as 1 mW/cm². The SPS system would deliver 23 mW/cm² at the rectenna center, 1 mW/cm² or less at the edge, and 0.1 mW/cm² at the buffer zone boundary. Current data show no morbid effects from 2,450-MHz radiation below 1 mW/cm², but long-term exposure studies are lacking.
