Orphan Source
An orphan source is a self-contained radioactive source that is no longer under proper regulatory control. The United States Nuclear Regulatory Commission defines an orphan source more exactly as: ...a sealed source of radioactive material contained in a small volume—but not radioactively contaminated soils and bulk metals—in any one or more of the following conditions *In an uncontrolled condition that requires removal to protect public health and safety from a radiological threat *Controlled or uncontrolled, but for which a responsible party cannot be readily identified *Controlled, but the material's continued security cannot be assured. If held by a licensee, the licensee has few or no options for, or is incapable of providing for, the safe disposition of the material *In the possession of a person, not licensed to possess the material, who did not seek to possess the material *In the possession of a State radiological protection program for the sole purpose of mitigati ...

State Of Mexico
The State of Mexico ( es, Estado de México; ), officially just Mexico ( es, México), is one of the 32 federal entities of the United Mexican States. Commonly known as Edomex (from ) to distinguish it from the name of the whole country, it is the most populous, as well as the most densely populated, state in the country. Located in South-Central Mexico, the state is divided into 125 municipalities. The state capital city is Toluca de Lerdo ("Toluca"), while its largest city is Ecatepec de Morelos ("Ecatepec"). The State of Mexico surrounds Mexico City on three sides and borders the states of Querétaro and Hidalgo to the north, Morelos and Guerrero to the south, Michoacán to the west, and Tlaxcala and Puebla to the east. The territory that now comprises the State of Mexico once formed the core of the Pre-Hispanic Aztec Empire. During the Spanish colonial period, the region was incorporated into New Spain.

North American Central Time Zone
The North American Central Time Zone (CT) is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean. Central Standard Time (CST) is six hours behind Coordinated Universal Time (UTC). During summer, most of the zone uses daylight saving time (DST), and changes to Central Daylight Time (CDT) which is five hours behind UTC. The largest city in the Central Time Zone is Mexico City; the Mexico City metropolitan area is the largest metropolitan area in the zone and in North America. Regions using (North American) Central Time Canada The province of Manitoba is the only province or territory in Canada that observes Central Time in all areas. The following Canadian provinces and territories observe Central Time in the areas noted, while their other areas observe Eastern Time: * Nunavut (territory): western areas (most of Kivalliq Region and part of Qikiqtaaluk Region) * Ontario (province): a port ...

Cobalt-60
Cobalt-60 (60Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2713 years. It is produced artificially in nuclear reactors. Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope . (PDF also located aCanadian Nuclear FAQ Measurable quantities are also produced as a by-product of typical nuclear power plant operation and may be detected externally when leaks occur. In the latter case (in the absence of added cobalt) the incidentally produced is largely the result of multiple stages of neutron activation of iron isotopes in the reactor's steel structures via the creation of its precursor. The simplest case of the latter would result from the activation of . undergoes beta decay to the stable isotope nickel-60 (). The activated nickel nucleus emits two gamma rays with energies of 1.17 and 1.33 MeV, hence the overall equation of the nuclear reaction (activation and decay) is: ...

Cobalt Therapy
Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer. Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient's body to kill tumor tissue. Because these "cobalt machines" were expensive and required specialist support, they were often housed in ''cobalt units''. Cobalt therapy was a revolutionary advance in radiotherapy in the post-World War II period but is now being replaced by other technologies such as linear accelerators. History Before the development of medical linear accelerators in the 1970s, the only artificial radiation source used for teletherapy was the x-ray tube. Researchers found ordinary x-ray tubes, which used voltages of 50-150 keV, could treat superficial tumors, but did not have the energy to reach tumors deep in the body. To have the penetrating ability to reach deep- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Populated Places In The State Of Mexico
Population typically refers to the number of people in a single area, whether it be a city or town, region, country, continent, or the world. Governments typically quantify the size of the resident population within their jurisdiction using a census, a process of collecting, analysing, compiling, and publishing data regarding a population. Perspectives of various disciplines Social sciences In sociology and population geography, population refers to a group of human beings with some predefined criterion in common, such as location, race, ethnicity, nationality, or religion. Demography is a social science which entails the statistical study of populations. Ecology In ecology, a population is a group of organisms of the same species who inhabit the same particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with in ...
