Our exposure to wireless radiation is steadily increasing. This radiofrequency (RF) radiation is currently classified as a Group 2B Possible Human Carcinogen by the International Agency for Research on Cancer at the WHO as of 2011. Many scientific experts who work in the field of EMR feel there is clear evidence of harm from long term, low level exposure to this pulsating and penetrating non-ionizing radiation which warrants an upgrade to the IARC classification to a Group 1 Known Carcinogen (Hardell and Carlsberg 2018).

It is important to be able to read the scientific literature, however, it can be confusing as there are different units of measurements (μW/cm2, μW/m2, W/m2, V/M). In addition, harm from radio frequency exposure varies with power, distance, device, modulation (pulsations and wave design), polarization and length of exposure.  Wall et al demonstrated that with a weak reception phone signal  radiation is magnitudes higher. The peak power and pulsation, rather than the averaged power, are the  important aspects of cellular injury.

It is important to keep in mind that the current thermal (heat) RF exposure standards vary in different countries. The biologically toxic (oxidative/membrane) RF exposure levels, shown to produce harm at non-thermal levels, are far below current U.S. RF guidelines (See BioInitiative Report). More lenient current U.S. FCC standards put large populations at risk for a diverse array of long term health issues.  We list several exposure standards and limits along with the short conversion chart to enable easier reading of the scientific literature.  The Austrian Medical Association Guidelines of 2016  are also posted below. Scientific references on exposure measurements are listed at the end (Ambient, Children, Skin and Body Exposures, Occupational)

Industry Standardization Worldwide?

Industry is trying to standardize all countries to allow higher levels of RF that are consistent with current IEEE & ICNIRP guidelines (Same as US and Canada) which do not take into account non thermal biological effects, only heat. Here is a slide presentation that helps to understand industry strategy. If this moves forward countries who wish to use lower precautionary limits will be unable to do so. TIA-MWF PowerPoint for FCC Labs and OET Meeting

Russia set lower standard than the U.S. and have not raised them. It is interesting to find that Russian researchers  looked at RFR exposures and immune dysfunction over 2 decades ago and because of these robust studies which were replicated in 2006-2009 they set their upper limit of RFR at 10 μW/cm2.

Here is a thorough discussion from the telecom industry, Preparing for 5G: Evolution of RF Compliance Standards and Regulations for Mobile Devices.

The Lancet Publishes Article on Planetary RF Exposures

A December 2018 article on planetary radio frequency (RF) exposures was published in the prestigious medical journal, The Lancet. Titled Planetary electromagnetic pollution: it is time to assess its impact, the authors discuss the flaws in current exposure guidelines, and show a graph indicating the changes in exposure levels of different frequencies over time. They call for this topic to be included with other critical issues related to planetary health, including climate change and rising levels of chemical toxins.

Austrian Medical Association (AMA) Exposure Limits

“In general, a wide variety of forms of EMF exposure (e.g. from cordless phones, wireless internet access, electrical installations and electrical devices in the building, mobile phone base stations, radio and TV transmitters, high-voltage lines or transformer stations) may be the root causes of health problems….Irrespective of the ICNIRP recommendations for acute effects, the following benchmarks apply to regular exposure of more than four hours per day…” AMA

The EUROPEAM EMF GUIDELINES 2016  for the prevention, diagnosis and treatment of EMF-related health problems and illnesses is based on the Austrian Medical Association Guidelines and  gives an “overview of the current knowledge regarding EMF-related health risks and provides recommendations for the diagnosis, treatment and accessibility measures of EHS to improve and restore individual health outcomes as well as for the development of strategies for prevention.” List of scientific references given. Here are their recommendations.

High-frequency electromagnetic radiation (as power flow density)

0.001
μW/cm2   to  0.1 μW/cm2   (10-1000 μW/m2) (0.01-1 mW/m2)- Far above normal

Less than 0.000,1 μW/cm2   (≤1 μW/m2) (≤0.001 mW/m2) – Within normal limits

“The benchmarks listed are intended to be applied to individual types of radiation, e.g. GSM, UMTS, WiMAX, TETRA, radio, TV, DECT or WLAN, and refer to peak levels [not averaged levels]. The benchmarks do not apply to radar, which must be evaluated separately. Highly critical types of radiation, such as periodic signals (mobile telephony, DECT, WLAN, digital broadcasting…), should be critically evaluated, especially if levels are far above normal, while less critical types, such as non-pulsed or non-periodic signals (USW, shortwave, medium and long wave, analogue broadcasting), may be considered more leniently.” AMA- Here are the EUROPEAM EMF Guidelines 2016 EHS – PDF to print or download.

Low-frequency Alternating Electric Fields

≥10 V/m  Very far above normal

1.5-10 V/m -Far above normal

0.3-1.5 V/m- Slightly above normal

≤0.3 V/m – Within normal limits

*The benchmarks (potential-free measurement) are intended to be applied to the range up to and around 50 Hz; higher frequencies and distinct harmonics should be more critically evaluated.

SAR Radiofrequency Radiofrequency Radiation Limits

SAR or Specific Absorption Rate is, according to the FCC,  a value that corresponds to the relative amount of RF energy absorbed in a biological tissue in watts per kilogram. This value is used as a government standard for lower frequencies of radiofrequency radiation exposures for portable and mobile wireless devices.

For the general population the FCC public exposure limit for  the  cellular telephones to the head is a SAR level of 1.6 watts per kilogram (1.6 W/kg) and averaged over 1 gram of tissue.  The FCC limit for the hand is  SAR of 4.0 W/kg and is measured at an average of 10g tissue. The FCC limit for general population/uncontrolled whole body exposure is 0.08 W/kg, as averaged over the whole body. Note “Exposure may be averaged over a time period not to exceed 30 minutes to determine compliance with general population/uncontrolled SAR limits”

Occupational limits for whole body exposure is  0.4W/kg and spatial pen SAR of 8W/kg averaged over 1 gm of tissue. Spatial peak SAR limits for hands, wrists, feet and ankles shall not exceed 20 W/kg, as averaged over any 10 grams of tissue (defined as a tissue volume in the shape of a cube).

Distances from Devices such as personal computers/laptops listed on page 15 and page 73  in FCC EOET Bulletin 65 . Occupational exposure limits listed on page 75.

Note: FCC– “The selection of the 20-cm value for differentiating between “portable” and “mobile”devices is based on the specification in the 1992 ANSI/IEEE standard that 20 cm should be the minimum separation distance where reliable field measurements to determine adherence to MPEs (maximum exposure limits) can be made.”

Note: FCC page 43- “The localized SAR criteria used by the FCC, and specified in the ANSI/IEEE 1992 standard, only apply at operating frequencies between 100 kHz and 6 GHz.” Above these frequencies power densities are used.

Exposure Limits Have Never Considered Long Term Exposure or Non-Thermal Bio-Effects

Here is a 1999  letter (posted on EHTrust.org), 1999-radiofrequency-interagency-workgroup,  from US Health and Human Services Radiofrequency Interagency Working Group to the Industry IEEE.  It states, “There is a need to discuss and differentiate the criteria for guidelines for acute and chronic exposure conditions. The past approach of basing the exposure limits on acute effects data with an extrapolation to unlimited chronic exposure durations is problematic. There is an extensive data base on acute effects with animal data, human data (e.g. MRI information), and modeling to address thermal insult and associated adverse effects for acute exposure (e.g., less than one day). For lower level (“non-thermal”), chronic exposures, the effects of concern may be very different from those for acute exposure (e.g., epigenetic effects, tumor development, neurologic symptoms). It is possible that the IEEE RF radiation guidelines development process may conclude that the data for these chronic effects exist but are inconsistent, and therefore not useable for guideline development. If the chronic exposure data are not helpful in determining a recommended exposure level, then a separate rationale for extrapolating the results of acute exposure data may be needed. In either case (chronic effects data that are useful or not useful), a clear rationale needs to be developed to support the exposure guideline for chronic as well as acute exposure.”

Exposure Limits for Radio frequency Energy: Three Models

Ken Foster, University of Pennsylvania, Philadelphia

This article points out that different long term exposure limits in different countries are due to their different models of reasoning.

  • Heat: The U.S. uses science based studies but only those that examine heat based adverse effects. They do not take into account studies on non-thermal adverse effects.
  • Non-Thermal Effects:  Russia and China use science based studies on non-thermal effects.
  • Precautionary: Switzerland, Italy and many other countries use precautionary language for their long term exposure limits

“Thus, Russian (and Eastern European) limits clearly reflect the conviction that long-term (hours or more) exposures at levels far below Western limits result in adverse health effects. Indeed, the Russian and Eastern European medical literature contains many reports of health effects from low-level exposure to RF energy. These include, for example, nonspecific problems (such as headaches, fatigability, irritability, sleep disorders, and dizziness) in workers in radio factories, who are exposed to RF energy at undetermined levels11 12. The Chinese literature contains similar reports.13 The Russian literature contains references to a “microwave disease” characterized by “asthenic, asthenovegetatic, and hypothalamic syndromes”14 The disease is not recognized in Western medicine, and its diagnostic criteria would undoubtedly strike many Western physicians as vague and nonfalsifiable. Even some Eastern European physicians have complained about the nonspecificity of these criteria as well.15 16″

  • High ambient radiofrequency radiation in Stockholm city, Sweden. (2019) Carlberg M et al. Oncology Letters. December 3, 2018. Pages: 1777-1783.  https://www.spandidos-publications.com/ol/17/2/1777    “The total mean level was 5,494 µW/m2 (median 3,346; range 36.6‑205,155). The major contributions were down links from LTE 800 (4G), GSM + UMTS 900 (3G), GSM 1800 (2G), UMTS 2100 (3G) and LTE 2600 (4G). Regarding different places, the highest RF radiation was measured at the Hay Market with a mean level of 10,728 µW/m2 (median 8,578; range 335‑68,815). This is a square used for shopping, and both retailers and visitors may spend considerable time at this place. Also, the Sergel Plaza had high radiation with a mean of 7,768 µW/m2. All measurements exceeded the target level of 30‑60 µW/m2 based on non‑thermal (no heating) effects, according to the BioInitiative Report.”
  • Radiofrequency radiation from nearby base stations gives high levels in an apartment in Stockholm, Sweden: A case report. (2018) Hardell L et al.  Oncology Letters. March 16, 2018. https://www.spandidos-publications.com/10.3892/ol.2018.8285 “The total mean RF radiation level was 3,811 µW/m2 (range 15.2‑112,318 µW/m2) for the measurement of the whole apartment, including balconies…. Due to the current high RF radiation, the apartment is not suitable for long‑term living, particularly for children who may be more sensitive than adults.”

Occupational Exposures

The Center for Construction Research and Training  in Maryland works to reduce or eliminate safety and health hazards that construction workers face on the job. They have compiled an abundance of useful information on the hazards for RF exposures as well as identifying RF exposures with different antenna. This is a great resource for information on cell antennae and FCC requirements.

Their Radiofrequency (RF) Radiation Awareness Guide for the Construction Industry is especially useful. https://www.cpwr.com/wp-content/uploads/publications/RF_Radiation_Awareness_Program_Guide_8_2016.pdf
