Prudent Avoidance Principle
Prudent avoidance is a precautionary principle in risk management. It states that reasonable efforts to minimise potential risks should be taken when the actual magnitude of the risks is unknown. The principle was proposed by Prof. Granger Morgan of Carnegie Mellon University in 1989 in the context of electromagnetic radiation safety (in particular, fields produced by power lines). A report for the Office of Technology Assessment of the US Congress described prudent avoidance of power line fields as: The principle has been adopted in a number of countries, for example Sweden, Denmark, Norway, Australia and New Zealand. While not adopted by any regulatory body at the national level in the USA, the principle has been adopted in some form by a number of local regulatory bodies, for example the public utility commissions in California, Colorado, Connecticut and Hawaii. The Colorado Public Commission states: {{quote, The utility shall include the concept of prudent avoi ...

Precautionary Principle
The precautionary principle (or precautionary approach) is a broad epistemological, philosophical and legal approach to innovations with potential for causing harm when extensive scientific knowledge on the matter is lacking. It emphasizes caution, pausing and review before leaping into new innovations that may prove disastrous. Critics argue that it is vague, self-cancelling, unscientific and an obstacle to progress. In an engineering context, the precautionary principle manifests itself as the factor of safety, discussed in detail in the monograph of Elishakoff. It was apparently suggested, in civil engineering, by Belindorde Bélidor, Bernard Forest, La science des ingénieurs, dans la conduite des travaux de fortification et d'architecture civile, Paris: Chez Claude Jombert 1729 in 1729. Interrelation between safety factor and reliability is extensively studied by engineers and philosophers. The principle is often used by policy makers in situations where there is the poss ...

Electromagnetic Radiation
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum. Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields. Depending on the frequency of oscillation, different wavelengths of electromagnetic spectrum are produced. In a vacuum, electromagnetic waves travel at the speed of light, commonly denoted ''c''. In homogeneous, isotropic media, the oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. The position of an electromagnetic wave within the electromagnetic spectrum can be characterized ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

US Congress
The United States Congress is the legislature of the federal government of the United States. It is bicameral, composed of a lower body, the House of Representatives, and an upper body, the Senate. It meets in the U.S. Capitol in Washington, D.C. Senators and representatives are chosen through direct election, though vacancies in the Senate may be filled by a governor's appointment. Congress has 535 voting members: 100 senators and 435 representatives. The U.S. vice president has a vote in the Senate only when senators are evenly divided. The House of Representatives has six non-voting members. The sitting of a Congress is for a two-year term, at present, beginning every other January. Elections are held every even-numbered year on Election Day. The members of the House of Representatives are elected for the two-year term of a Congress. The Reapportionment Act of 1929 establishes that there be 435 representatives and the Uniform Congressional Redistricting Act requi ...

Connecticut
Connecticut () is the southernmost state in the New England region of the Northeastern United States. It is bordered by Rhode Island to the east, Massachusetts to the north, New York to the west, and Long Island Sound to the south. Its capital is Hartford and its most populous city is Bridgeport. Historically the state is part of New England as well as the tri-state area with New York and New Jersey. The state is named for the Connecticut River which approximately bisects the state. The word "Connecticut" is derived from various anglicized spellings of "Quinnetuket”, a Mohegan-Pequot word for "long tidal river". Connecticut's first European settlers were Dutchmen who established a small, short-lived settlement called House of Hope in Hartford at the confluence of the Park and Connecticut Rivers. Half of Connecticut was initially claimed by the Dutch colony New Netherland, which included much of the land between the Connecticut and Delaware Rivers, although the first ...
