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 publication is designed to provide factual information to the public by answering some of the most commonly asked questions. The phrase fully aware in the context of applying these exposure limits means that an exposed person has received written and/or verbal information fully explaining the potential for RF exposure resulting from his or her employment. Frequencies are a combination of 850 and 1900 or 900 and 1800 MHz. Each writer is expressing his or her own opinions and they are not necessarily the opinions of the group at large or of any employer of individuals of the group. These are pulsed signals and  used in the first digital cell phones. The FCC’s multipronged effort is divided into four parts:  Resolution of Notice of Inquiry and closure of ET Docket No. These criteria for SAR evaluation are similar to those recommended by the National Council on Radiation Protection and Measurements (NCRP) in “Biological Effects and Exposure Criteria for Radiofrequency Electromagnetic Fields,” NCRP Report No. Occupational exposure limits listed on page 75. The new guidelines for cellular base stations are identical to those recommended by the National Council on Radiation Protection and Measurements (NCRP) discussed on page 2 of the FCC information sheet. 1G – Analog- Advanced Mobile Phone Service (AMPS) was commercially introduced in the 1980’s and operated with voice only at 800 MHz with a continuous wave signal. 2G – Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA), are variants of 2G systems, introduced in 1990’s providing text messaging, multimedia messaging and internet access. 1.1307(b), 1.1310, 2.1091, 2.1093]. 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. Once you are there you will see instructions for inserting the FCC ID number. EU standards have changed and there may be mandated lower limits. https://www.fcc.gov/general/oet-bulletins-line, Electronic Code of Federal Regulations (e-CFR), Chapter I. (4) Both the MPE limits listed in Table 1 in paragraph (e)(1) of this section and the SAR limits as set forth in paragraphs (a) through (c) of this section are for continuous exposure, that is, for indefinite time periods. Radiofrequency (RF) and microwave (MW) radiation are electromagnetic radiation in the frequency ranges 3 kilohertz (kHz) - 300 Megahertz (MHz), and 300 MHz - 300 gigahertz (GHz), respectively. 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.”. The Lancet Publishes Article on Planetary RF Exposures. Peter Sierk. Prof. Yu. MRI information), and modeling to address thermal insult and associated adverse effects for acute exposure (e.g., less than one day). The FCC is required by the National Environmental Policy Act of 1969, among other things, to evaluate the effect of emissions from FCC-regulated transmitters on the quality of the human environment. With the exception of transient persons, this phrase also means that an exposed person has received appropriate training regarding work practices relating to controlling or mitigating his or her exposure. The peak power and pulsation, rather than the averaged power, are the  important aspects of cellular injury. 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). Wall et al demonstrated that with a weak reception phone signal  radiation is magnitudes higher. (c) The SAR limits for general population/uncontrolled exposure are 0.08 W/kg, as averaged over the whole body, and a peak spatial-average SAR of 1.6 W/kg, averaged over any 1 gram of tissue (defined as a tissue volume in the shape of a cube). These SAR limits to be used for evaluation are based generally on criteria published by the American National Standards Institute (ANSI) for localized SAR in Section 4.2 of “IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz,” ANSI/IEEE Std C95.1-1992, copyright 1992 by the Institute of Electrical and Electronics Engineers, Inc., New York, New York 10017. The past approach of basing the exposure limits on acute effects data with an extrapolation to unlimited chronic exposure durations is problematic. In the Report and Order and a Memorandum Opinion and Order, the FCC adopts several issues since they were initiated in 2003 and further extended by proposals in 2013 that revise and update its regulations implementing NEPA. Several organizations, such as the American National Standards Institute (ANSI), the Institute of Electrical and Electronics Engineers, Inc. (IEEE),and the National Council on Radiation Protection and Measurements (NCRP) have issued recommendations for human exposure to RF electromagnetic fields. (3) General population/uncontrolled exposure limits apply in situations in which the general public may be exposed, or in which persons who are exposed as a consequence of their employment may not be fully aware of the potential for exposure or cannot exercise control over their exposure. 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. This technical bulletin was issued to provide guidance in the implementation of the Commission's new exposure limits and policies. The LSGAC and the FCC have developed this guide to aid local governmental officials and citizens in understanding safety issues related to radio frequency emissions from telecommunications towers. Please see the SAR information page on the Consumer & Governmental Affairs Bureau for links to cellular phone manufacturers. 47 CFR § 1.1310 – Radiofrequency radiation exposure limits listed here. Wireless Exposure Limits in Different Countries The limits are for frequencies between 300Mhz-300GHz in microwatts/cm2 Limit guidelines in U.S. are from 200 uW/cm2 to 1000 uW/cm2 (2 W/m 2 to 10 W/m2) for RF radiation depending on frequency. © 2016 Physicians for Safe Technology (mdsafetech.org). In the frequency range from 100 MHz to 1500 MHz, these MPE exposure limits for field strength and power density are also generally based on criteria recommended by the ANSI in Section 4.1 of “IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz,” ANSI/IEEE Std C95.1-1992, copyright 1992 by the Institute of Electrical and Electronics Engineers, Inc., New York, New York 10017. For phones and devices authorized between about mid-1998 and June 2000, detailed information on SAR levels is typically found in the "exhibits" associated with the grant of equipment authorization. 13-84, a Report and Order and a Memorandum Opinion and Order and closure of ET Docket No. More lenient current U.S. FCC standards put large populations at risk for a diverse array of long term health issues. Countries developed different standards based on either  *Thermal Effects *Non-Thermal Effects or *Precautionary Considerations. Scientific references on exposure measurements are listed at the end (Ambient, Children, Skin and Body Exposures, Occupational), 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. Even some Eastern European physicians have complained about the nonspecificity of these criteria as well.15 16″, http://www.who.int/peh-emf/meetings/day2Varna_Foster.pdf. Go to the following Web site: Equipment Authorization. f = frequency in MHz. 3G – Universal Mobile Telecommunications Service (UMTS)– Introduced in 1998 with broadband features providing data transfer, mobile internet and video calling. For portable phones and devices authorized since June 2, 2000, maximum SAR levels should be noted on the grant of equipment authorization. Limit guidelines in U.S. are from 200 uW/cm2 to 1000 uW/cm2 (2 W/m2 to 10 W/m2) for RF radiation depending on frequency. The FCC has divided this process into three parts:  a Report and Order (Order) and a Further Notice of Proposed Rulemaking (Further Notice) in ET Docket No. This value is used as a government standard for lower frequencies of radiofrequency radiation exposures for portable and mobile wireless devices. This section should contain the value(s) for typical or maximum SAR for your phone. The grant of equipment authorization for this particular ID number should appear. 56: Questions and Answers About Biological Effects Potential Hazards of Radio frequency Electromagnetic Fields (Fourth Edition, August 1999). The Austrian Medical Association Guidelines of 2016  are also posted below. 65: Evaluating Compliance With FCC Guidelines for Human Exposure to Radio frequency Electromagnetic Fields. In the frequency range from 100 MHz to 1500 MHz, exposure limits for field strength and power density are also generally based on the MPE limits found in Section 4.1 of “ IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz,” ANSI/IEEE C95.1-1992 (IEEE, 1992, and approved for use as an American National Standard by the American … The FCC ID number is usually shown somewhere on the case of the phone or device. This article points out that different long term exposure limits in different countries are due to their different models of reasoning. Then click on "Start Search." [Acrobat | News Release]. High-frequency electromagnetic radiation (as power flow density), 0.1 μW/cm2   (≥1000 μW/m2 ) (≥1 mW/m2)—Very  far above normal Here is a thorough discussion from the telecom industry, Preparing for 5G: Evolution of RF Compliance Standards and Regulations for Mobile Devices. The bulletin provides acceptable methods of determining compliance to Commission limits through the use of mathematical and empirical models. 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. MDSafeTech.org is therefore not liable for damages resulting from the use of information obtained from this site or from sites linked to it. * = Plane-wave equivalent power density. = 0.000,000,01 μW/cm2, 0.000,614 V/m = 0.614 mV/m = 0.001 μW/m2. Specific Absorption Rate (SAR) for Wireless Phones and Devices Available at FCC Web Site. Russia set lower standard than the U.S. and have not raised them. The FCC looks forward to developing a complete record by soliciting the input of qualified expert agencies and organizations and the public, to determine whether the current rules and policies should remain unchanged, or should be relaxed or tightened. Table 1 to § 1.1310(e)(1) - Limits for Maximum Permissible Exposure (MPE). For devices that only expose part of the body, such as mobile phones, different exposure limits are specified (see below). The FCC adopted guidelines for hand-held RF devices, such as cellular telephones, that are the same as those recommended by the 1992 ANSI/IEEE guidelines, discussed on page 4 of the information sheet.
