Frequently Asked Questions

HOW IS RADIOFREQUENCY ENERGY USED?

OET -- RF Safety FAQ's
Probably the most important use for RF energy is in providing telecommunications services. Radio and television broadcasting, cellular telephones, personal communications services (PCS), pagers, cordless telephones, business radio, radio communications for police and fire departments, amateur radio, microwave point-to-point links and satellite communications are just a few of the many telecommunications applications of RF energy.

WHERE CAN I OBTAIN MORE INFORMATION ON POTENTIAL HEALTH EFFECTS OF RADIOFREQUENCY ENERGY?

OET -- RF Safety FAQ's
Although relatively few offices or agencies within the Federal Government routinely deal with the issue of human exposure to RF fields, it is possible to obtain information and assistance on certain topics from the following federal agencies. Most of these agencies also have Internet Web sites.

WHAT EQUIPMENT IS USED FOR RADIOFREQUENCY ABLATION?

Cancer Therapy - Radiofrequency Ablation
There are three basic types of systems used for RF ablation procedures. The specific RFA system and guidance method are chosen based on location and size of the tumor to be treated, proximity of large vessels, bleeding risk, the pathway that the needle-electrode has to take to enter the tumor, and the importance of minimizing collateral damage. The systems differ based on the length and configuration of the active tip of the needle-electrode.

Is radiofrequency (RF) energy safe for use on the eye?

Maloney Vision Institute: Conductive Keratoplasty Frequently...
Yes. The use of RF energy is one of today’s most advanced surgical techniques. In addition to its use in CK, RF technology is being used in prostate cancer therapy, back surgery, even cardiovascular procedures.

HOW HAVE PEOPLE USED GEOTHERMAL ENERGY IN THE PAST?

Geothermal Education Office - Power From the Earth's Heat
From earliest times, people have used geothermal water that flowed freely from the earth's surface as hot springs. The oldest and most common use was, of course, just relaxing in the comforting warm waters. But eventually, this "magic water" was used (and still is) in other creative ways. The Romans, for example, used geothermal water to treat eye and skin disease and, at Pompeii, to heat buildings.

Can roadside land and interstate medians be used for energy crops, and how tall are they?

Bioenergy and Biomass Frequently Asked Questions
Potentially these lands could be used for bioenergy crop production. This might be a good use of such lands because the crops would take up carbon dioxide, sequester carbon in their above and below-ground growth, remove other pollutants from the air, and minimize maintenance needs and fossil energy use for grass-cutting, etc. However, harvesting and removing the crops safely might present problems, and there may be no markets nearby for the biomass, making transport rather expensive.

How is the income from the sale of energy used?

Bureau of Reclamation: Lower Colorado Region - Hoover Dam Po...
To pay all operation and maintenance expenses and to repay the major part of the construction cost of the dam and powerplant, at interest not exceeding 3 percent. The cost of construction completed and in service by 1937 was repaid on May 31, 1987. All other costs, except those for flood control, will be repaid within 50 years of the date of installation or as established by Congress. Repayment of the $25 million construction cost allocated to flood control is currently deferred.

Can antimatter be used for energy storage?

Antimatter FAQ
Yes. For storing small amounts of energy in an extremely compact way, antimatter is very useful. The energy density stored in antimatter is about 1 billion times higher than in batteries. But: the amount of antimatter that is produced each year in big accelerator labs such as CERN or Fermilab corresponds to an energy that would allow a 100 W light bulb shine for 15 minutes.

What is 'AUXILLARY' energy used for?

National Calculation Method
The auxiliary energy figures for this system include an allowance for the fans in the fan coil units, (and there is a minimum acceptable performance figure in the HVAC guide - 0.8 based on the average of all fan coils). The SFP that users input should be just for the central plant - the fan coil allowance will be included automatically. Similarly, the flow rate should be for the central plant.

What is the energy drink and water that is used?

FAQ
The Marine Corps Marathon will ofofer Powerade and water at each water point as well as at the Hospitality tent, just past the finish line.

How is wind energy used?

Welcome to Fire Mountain Solar -Solar Electric Solar Panels ...
Wind turbines are very useful in almost any marine or household electrical system. In marine use, the movement of the boat will raise enough breeze to get the generator turning even when actual winds are fairly low, making them an extremely reliable source of onboard power. For residential systems, wind power can be a wonderful source of power during low-light winter months and even year-round, depending on the site.

How much water and energy is used per wash?

Netwash_HomePage
Answer: NO! When the pet is introduced for the first time to the cabin, naturally, it does not know what to expect. When water starts to spray on the pet from several directions, it will catch it by surprise. Once the pet realizes that it’s ONLY WATER, and that the warm pulsating streams actually feel good, it soon begins to relax and will either stand still or sit down and look out the window.

How much biomass is used for energy today?

Biofuels: an overview brought to you by Energylinx
Worldwide, biomass is the fourth largest energy resource after coal, oil, and natural gas. It is used for heating (such as wood stoves in homes and for process heat and steam in industries such as pulp and paper), cooking (especially in many parts of the developing world), transportation (fuels such as ethanol and biodiesel) and for electric power generation. It is estimated that there are about 278 Quadrillion Btu of installed biomass capacity worldwide.

HOW IS RADIOFREQUENCY RADIATION MEASURED?

OET -- RF Safety FAQ's
RF electromagnetic wave or RF "field" has both an electric and a magnetic component (electric field and magnetic field), and it is often convenient to express the intensity of the RF environment at a given location in terms of units specific for each component.

CAN RADIOFREQUENCY RADIATION CAUSE CANCER?

OET -- RF Safety FAQ's
Some studies have also examined the possibility of a link between RF and microwave exposure and cancer. Results to date have been inconclusive. While some experimental data have suggested a possible link between exposure and tumor formation in animals exposed under certain specific conditions, the results have not been independently replicated. In fact, other studies have failed to find evidence for a causal link to cancer or any related condition.

What is radiofrequency radiation?

Frequently Asked Questions
Radiofrequency (RF) fields are part of the electromagnetic (EM) spectrum. The EM spectrum is divided into ionizing and non-ionizing bands based on how the wave interacts with biological tissue. The non-ionizing portion, usually in the frequency range up to 300 GHz, doesn't affect biological tissue and includes the extremely low frequency (ELF) band, radio waves and microwaves in the radiofrequency communication band, and infrared and visible light.
