Federal Reserve System, central banking system of the United States, popularly called the Fed. A central bank serves as the banker to both the banking munity and the government; it also issues the national currency, conducts moary policy, and plays a major role in the supervision and regulation of banks and bank holding panies. In the U.S. these function are the responsibilities of key officials of the Federal Reserve System: the Board of Governors, located in Washington, D.C., and the top officers of 12 district Federal Reserve banks, located throughout the nation. The Fed’s actions, described below, generally have a

significant effect on U.S. interest rates and, subsequently, on stock, bond, and other financial markets.

The Federal Reserve’s basic powers are concentrated in the Board of Governors, which is paramount in all policy issues concerning bank regulation and supervision and in most aspects of moary control. The board enunciates the Fed’s policies on both moary and banking matter. Because the board is not an operating agency, most of the day-to day implementation of policy decisions is left to the

district Federal Reserve banks, stock in which is owned by the mercial banks that are members of the Federal Reserve System. Ownership in this instance, however, does not imply control; the Board of Governors and the heads of the Reserve banks orient their policies to the public interest rather than to the benefit of the private banking system. The U.S. banking system’s regulatory apparatus is plex; the authority of the Federal Reserve is shared in some instances for example, in mergers or the examination of banks with other Federal Deposit Insurance Corporation (FDIC). In the critical area of regulating the nation’s money supply in aordance with national economic goals, however, the Federal Reserve is independent within the government, Ine and expenditures of the Federal Reserve banks and of the board of governors are not subject to the congressional appropriation process; the Federal Reserve is self-financing. Its ine ($20.2 billion in 1992) es mainly from Reserve bank holdings of ine-earning securities, primarily those of the U.S. government. Outlays ($1.5 billion in 1992) are mostly for operational expenses in providing services to the government and for expenditures connected with regulation and moary policy. In 1992 the Federal Reserve returned 416.8 billion in earnings to the U.S. treasury.

The food irradiation process is a simple one. The new U.S. plant, Vindicator of Florida Incorporated in Mulberry, Fla., uses a material called cobalt 60 to irradiate food. Cobalt 60 is radioactive isotope (form) of the metallic element cobalt. Cobalt 60, which gives off radiation in the form of gamma rays, is also used for radiation therapy for cancer patients and for sterilizing hospital equipment. The radioactive isotope is created by bombarding cobalt with subatomic particles in a nuclear reactor. However, irradiation plants do not themselves contain nuclear reactors.

In the irradiation plant, food is exposed to thin rods of cobalt 60. The rods give off gamma rays, which disrupt chemical processes in contaminating organisms. The disruption breaks down the cell walls of organisms or destroys their geic material. The dose, set by the U.S. Food and Drug Administration (FDA), is enough to kill organisms on food, but not enough to produce significant changes in the food itself.

Although irradiation slightly decreases the nutritive value of foods, the loss is less than that produced by some other methods of food preservation. Canning, for example, results in a much greater loss of nutrients.

Those who object to irradiation say that the process may create substances not found in nonirradiated food. Since the 1960’s researchers have studied irradiated food at microscopic levels to try to find such substances, called unique radiolytic products. After reviewing these studies, the FDA determined that pounds formed during irradiation are similar to substance found in nonirradiated foods and are not dangerous to consume.

Destruction of microorganisms that cause illness is an important goal of irradiation. About 250 million cases of food poisoning or 1 per person—our every year in the U.S., aording to FDA estimates. Food poisoning can cause vomiting, diarrhea, fever, headache—and, oasionally, death.

Because of the apparent safety of food irradiation, and the problems presented by contaminated food, scientific groups—including the American Medical Association, the World Health Organization, and the United Nations food and Agriculture Association—have voiced nearly universal support for the process. Worldwide, 38 nations have approved irradiation for 355 products.

Like microwave ovens, food irradiation has aroused apprehension and misunderstanding. Yet it has been scrutinized more thoroughly than other methods of food treatment that we have e to regard as safe, and it appears to be a method whose time has e.
