Electromagnetic shielding is the process of lowering the electromagnetic field in an area by barricading it with conductive or magnetic material. Copper is used for radio frequency (RF) shielding because it absorbs radio and other electromagnetic waves. Properly designed and constructed RF shielding enclosures satisfy most RF shielding needs ...
Drolet's 1990 Rhumart system, a PEMF device. Pulsed electromagnetic field therapy ( PEMFT, or PEMF therapy ), also known as low field magnetic stimulation ( LFMS) is the use of electromagnetic fields in an attempt to heal non-union fractures and depression. [1] By 2007 the FDA had cleared several such stimulation devices.

Extremely low frequency ( ELF) is the ITU designation [1] for electromagnetic radiation ( radio waves) with frequencies from 3 to 30 Hz, and corresponding wavelengths of 100,000 to 10,000 kilometers, respectively. [2] [3] In atmospheric science, an alternative definition is usually given, from 3 Hz to 3 kHz. [4] [5] In the related magnetosphere ...
A new law in California will require bars and clubs to offer drug-testing devices in an effort to protect patrons from drinks spiked with "date rape drugs." The law, Assembly Bill 1013 , took ...
Covered California is the health insurance marketplace in the U.S. state of California established under the federal Patient Protection and Affordable Care Act (ACA). The exchange enables eligible individuals and small businesses to purchase private health insurance coverage at federally subsidized rates. It is administered by an independent ...
An EMF meter is a scientific instrument for measuring electromagnetic fields (abbreviated as EMF). Most meters measure the electromagnetic radiation flux density (DC fields) or the change in an electromagnetic field over time (AC fields), essentially the same as a radio antenna, but with quite different detection characteristics.
