Radiofrequency and Microwave Radiation
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. Research
continues on possible biological effects of exposure to RF/MW radiation from radios, cellular phones,
the processing
and cooking of foods, heat sealers, vinyl welders, high frequency welders, induction
heaters, flow solder machines, communications transmitters, radar transmitters, ion
implant equipment, microwave drying equipment, sputtering equipment and glue
curing.
There are no specific standards for radiofrequency
and microwave radiation issues.
Standards
This section highlights OSHA standards,
standard interpretations (official interpretation of the standards), other
federal, national consensus, and foreign national standards relevant to
radiofrequency and microwave radiation.
OSHA
Note: Twenty-five states, Puerto Rico and the Virgin
Islands have OSHA-approved State Plans and have adopted their own standards and
enforcement policies. For the most part, these States adopt standards that are
identical to Federal OSHA. However, some States have adopted different standards
applicable to this topic or may have different enforcement policies.
General Industry (29 CFR
1910)
-
1910 Subpart
G, Occupational health and environmental control
- 1910.97,
Nonionizing radiation. The exposure limit in this standard (10 mW/sq. cm.) is
expressed in voluntary language and has been ruled unenforceable for
Federal OSHA enforcement. The standard does specify the design of
an RF warning sign. Newer designs are also acceptable. [related topic

that workers
near RF sealers may be unaware of their exposure to RF emissions,
because the RF energy from sealers and heaters can penetrate deeply into
the body without activating the heat sensors located in the skin. The
results of a NIOSH study indicate that the majority of the workers
surveyed were exposed to RF energy at levels exceeding values citable by
OSHA. An extensive list of occupations involving the use of RF sealers

in 1995 and 1996.
Magnetic Resonance Imaging (MRI)
Hazard Locations and Solutions
In recent years there has been
considerable discussion and concern about the possible hazards of RF/MW radiation.
Extensive research on this topic is underway in many countries. Natural
low-frequency EM fields come from two main sources: the sun, and thunderstorm
activity, but man-made fields at much higher frequencies have altered this
natural EMF. At sufficiently high power densities, RF/MW energy can cause thermal effects
that can cause blindness, and sterility. Non-thermal effects, such as
alteration of the human body's circadian rhythms, immune system and the nature of the
electrical and chemical signals communicated through the cell membrane have been
demonstrated.
However, none of the research has
conclusively proven that low-level RF/MW radiation causes adverse health
effects.

Interference with Medical Devices
- Human Exposure to Radio Frequency and Microwave Radiation from Portable and Mobile Telephones and Other Wireless Communication Devices.
Institute of Electrical and Electronics Engineers (IEEE) Committee on Man
and Radiation (COMAR), (2000, September). Reports that sufficiently high levels of RF energy
can interfere with other electronic equipment. This problem is more likely to
occur with pulsed energy, which characterizes digital cellular telephones.
Studies have shown that handheld cellular phones can affect the operation of
heart pacemakers or defibrillators if the phone is placed directly over the
device, and there have been reports of interference between cell phones and
hearing aids. Individuals with pacemakers, implantable defibrillators, or
other body-mounted medical electronic devices, should consult with their
physician and/or the phone manufacturer to determine what precautions, if any,
should be taken. Some manufacturers recommend that cell phones be used on the
other side of the body from the implanted pacemaker.
-
Electromagnetic Compatibility - EMC. Food and Drug Administration (FDA),
Center for Devices and Radiological Health (CDRH).
- Update on Cellular phone Interference with Cardiac Pacemakers.
(1995, November 1). Reports interference with the
pacemaker's normal delivery of pulses can occur when
some cellular phones are placed very close to implanted cardiac pacemakers, The
type of interference under study is called "electromagnetic interference", or
"Emi". The CDRH concludes that interference issues are limited
to TDMA-type digital technologies, and further, that a distance separation of
~6 inches (~15 cm) is sufficient to mitigate EMI.

If a mobile-phone user wants to reduce his or her
exposure to RF energy, for whatever reason, he or she can:
- Limit the duration of calls
- Use a digital handset instead of an older
analog model. In most, but not all cases, digital handsets operate
at lower power levels than analog models. (The actual power level,
however, depends on local conditions and can vary greatly.)
- Use "hands-free kits", which move the handset
away from the body.
- Human Exposure to Radio Frequency and Microwave Radiation from Portable and Mobile Telephones and Other Wireless Communication Devices.
Institute of Electrical and Electronics Engineers (IEEE) Committee on Man and Radiation
(COMAR), (2000, September). Indicates that local SARs produced by hand-held, transportable, and
mobile transceivers and cellular telephones normally do not exceed FCC
and other safety limits. Present scientific evidence, as reviewed by
standards setting organizations and other expert groups, does not
demonstrate health or safety risks from cellular and other
communications transceivers. A potential exists for interference between
hand-held units and some medical devices that may be located in close
proximity to them (within a few centimeters).
- Physical Agents Data Sheets (PADs) - Radiofrequency/Microwave Radiation.
Alaska Department of Labor and Development. Requires employers who have people working around
devices which produce radiofrequency/microwave radiation ensure
that those devices are properly shielded to prevent leakage of
radiation. The State of Alaska in its Alaska Occupational Safety and
Health Standards has specified for incident electromagnetic energy
frequencies from 10 MHz to 100 GHz, a Permissible Exposure Limit (PEL) of 10 mW/cm
as averaged over any possible six-minute period.
Heating and Sealing Devices
-
Radiofrequency (RF) Sealers and Heaters. OSHA, the US Department of Health and Human Services (DHHS), and the National
Institute for Occupational Safety and Health (NIOSH) Joint NIOSH/OSHA
Current Intelligence Bulletin No. 33, (1979, December 4). Recommends that precautionary measures be
instituted to minimize the risk to workers from unwarranted exposure to RF
energy. The following controls are recommended:
- Properly design and install shielding material.
- Maximize the distance between the worker and the source of RF energy
emission should be maximized. Examples of means to accomplish this include
the use of automatic feeding devices, rotating tables, and remote materials
handling.
- Tune the equipment electronically to minimize the stray power emitted.
- Whenever possible, equipment switch off equipment when it is not being
used. Maintenance and adjustment of the equipment should be performed only
while the equipment is not in operation.
- After the performance of maintenance or repair, all machine parts,
including cabinetry, should be reinstalled so that the equipment is intact
and its configuration is unchanged.
- Post warnings and information.
- Develop a medical surveillance program tailored to the expected degree
of employee use of RF equipment and potential for exposure to RF energy.
- Take exposure measurements at regular intervals.
-
Physical Agents Data Sheets (PADs) - Radiofrequency/Microwave Radiation - Safety and Health Precautions. Alaska Department of Labor and Workforce Development. Reports radiofrequency sealers and heaters have been among the
major sources of employee exposure to radiofrequency/microwave radiation.
- When these machines are used, employees should use
mechanical or electrical devices that allow them to stay as far away form the
source of radiation as possible.
- Whenever possible, these sealers should be turned off
when not being used. Maintenance and adjustment of this type of equipment
should be performed only by trained technicians and only when the machines are
turned off.
- Warnings should be posted to keep everyone away from
the source of radiation except for those workers who are absolutely essential
to performing the job.
Microwave Ovens
-
Microwave Ovens and their Hazards. Canadian Centre for Occupational
Health and Safety (CCOHS).
Identifies old or faulty door
seals as the most common causes of microwave radiation leakage. Mechanical
abuse, a build-up of dirt, or simple wear and tear of continued use can cause
door seals to be less effective. Theoretically, there will be small amounts of
leakage through the viewing glass but measurements have shown this to be
insignificant. Safety tips for installation and maintenance of microwave ovens
include:
- Take special care to ensure that no damage occurs to the part of the
oven making contact with the door or door seals.
- Ensure that the microwave is unplugged or disconnected from electrical
power before reaching into any accessible openings or attempting any
repairs.
- Ensure that the adjustment of applied voltages, replacement of the
microwave power generating component, dismantling of the oven components,
and refitting of waveguides are undertaken only by persons
who have been specially trained for such tasks. The services of a qualified
repairman should be sought when any malfunction is suspected.
- Do not by pass the door interlocks.
- Do not test a microwave power generating component without an
appropriate load connected to its output. The power generated must never be
allowed to radiate freely into occupied areas.
-
Microwave Oven. Food and Drug Administration (FDA), Center for Devices and
Radiological Health (CDRH). Contains FAQs about

-
Occupational Exposure of Police
Officers to Microwave Radiation from Traffic Radar Devices.
National Institute for Occupational Safety and Health (NIOSH),
National Technical Information Service (NTIS) Publication No. PB95-261350, (1995,
June). Recommends police officers take some simple steps which
will sharply reduce their exposure to the low-level microwave radiation which
these devices emit.
- Always point the device away from the police officer's body, or his/her partner's body,
while it is turned on.
- Mount fixed radar antennas so that the beam is not pointed at any
occupant of the patrol car.
- Whenever possible, turn off a hand-held unit when it is not in use. If
the police officer's unit has a "standby" mode, always use it when not measuring the speed
of a vehicle. Never rest the unit against the officer's body when it is turned on.
- When it is on, try to avoid pointing the device toward metal surfaces
inside the police officer's car, such as the floor or a door, to avoid microwave reflection.
Evaluating RF and Microwave Exposure
RF energy includes frequencies ranging from about
3000 cycles per second (3 kHz) to 300 billion cycles per second (300 GHz).
Microwaves are a subset of radio waves and includes frequencies ranging from around
300 million cycles per second (300 MHz) to 3
GHz. RF exposures are directly linked to
absorption and distribution of RF energy in the body, and the absorption and
distribution are strongly dependent on body size and orientation and on
frequency and polarization of the incident radiation. A common measure of exposure is the Specific Absorption Rate
(SAR), the rate of energy absorption in tissue, measured in watts per kilogram
of tissue.

The FCC's New RF-Exposure Regulations. Describes the FCC regulations which identify
Maximum Permissible Exposure (MPE) derived from the Specific Absorption Rate
(SAR) at which tissue absorbs RF energy, expressed in watts per kilogram (W/kg).
From a safe SAR, the Standards and regulations set MPEs that vary with
frequency. Human-body resonances fall in the frequency range from 30 to
300 MHz and are the most strictly controlled. The regulations define two primary
RF-exposure environments "controlled/occupational" and "uncontrolled/general
public." In a "controlled" RF environment people know that RF is present and can
take steps to control their exposure. This applies to areas where you control
access. The limits for controlled environments are evaluated differently (less
stringent) than those for uncontrolled environments.
