Sunshine Units
The strontium unit is a unit used to measure the amount of radioactivity from strontium-90, a radionuclide found in nuclear fallout, in a subject's body. Since the human body absorbs strontium as if it were calcium, incorporating it into the skeleton, its presence is very common. One strontium unit is equal to one picocurie from strontium-90 per gram of calcium (37 becquerels per kilogram) in the subject's skeleton. The United States National Academy of Sciences holds that the maximum safe measure of strontium-90 in a person is one hundred strontium units (3700 Bq/kg). The average American is estimated to have three to four strontium units. The strontium unit was formerly known briefly as the sunshine unit, a doublespeak term promoted by the United States Department of Defense until public ridicule brought about its disuse. Among the sources of this outcry was a George Carlin performance, released on the CD '' Parental Advisory: Explicit Lyrics'', during a passage on governmen ...

Physical Unit
A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement. For example, a length is a physical quantity. The metre (symbol m) is a unit of length that represents a definite predetermined length. For instance, when referencing "10 metres" (or 10 m), what is actually meant is 10 times the definite predetermined length called "metre". The definition, agreement, and practical use of units of measurement have played a crucial role in human endeavour from early ages up to the present. A multitude of systems of units used to be very common. Now there is a global standard, the International System of Units (SI), the modern form of the metric system. In trade, weights and measures is often a subject of governmental regulation, to ensure fairness and transparency. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States National Academy Of Sciences
The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM).

Banana Equivalent Dose
Banana equivalent dose (BED) is an informal unit of measurement of ionizing radiation exposure, intended as a general educational example to compare a dose of radioactivity to the dose one is exposed to by eating one average-sized banana. Bananas contain naturally occurring radioactive isotopes, particularly potassium-40 (40K), one of several naturally occurring isotopes of potassium. One BED is often correlated to 10 sievert (0.1 μSv); however, in practice, this dose is not cumulative, as the potassium in foods is excreted in urine to maintain homeostasis. The BED is only meant as an educational exercise and is not a formally adopted dose measurement. History The origins of the concept are uncertain, but one early mention can be found on the RadSafe nuclear safety mailing list in 1995, where Gary Mansfield of the Lawrence Livermore National Laboratory mentions that he has found the "banana equivalent dose" to be "very useful in attempting to explain infinitesimal doses (and c ...

Project SUNSHINE
Project SUNSHINE was a series of research studies that began in 1953 to ascertain the impact of radioactive fallout on the world's population. The project was initially kept secret, and only became known publicly in 1956. Commissioned jointly by the United States Atomic Energy Commission and USAF Project Rand, SUNSHINE sought to examine the long-term effects of nuclear radiation on the biosphere due to repeated nuclear detonations of increasing yield. With the conclusion from Project GABRIEL that radioactive isotope Sr-90 represented the most serious threat to human health from nuclear fallout, Project SUNSHINE sought to measure the global ersion of Sr-90 by measuring its concentration in the tissues and bones of the dead. Of particular interest was tissue from the young, whose developing bones have the highest propensity to accumulate Sr-90 and thus the highest susceptibility to radiation damage. SUNSHINE elicited a great deal of controversy when it was revealed that many of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project GABRIEL
Project GABRIEL was an investigation to gauge the impact of nuclear fallout resulting from nuclear warfare. The United States Atomic Energy Commission surmised that the radioactive isotope strontium-90 (Sr-90) presented the greatest hazard to life globally, which resulted in the commissioning of Project SUNSHINE: which sought to examine the levels of Sr-90 in human tissues and bones (with a special interest in infants) gathered from around the world. Background During the Cold War era, there was an escalation of the atmosphere testing of nuclear weapons. After the atomic bombings of Hiroshima and Nagasaki in 1945, testing continued and the scale increased with the first hydrogen bomb in 1952. Soon after the United States tested the hydrogen bomb, the Soviet Union followed, in 1953. The mushroom clouds that occurred from the explosions released radioactive isotopes in mass quantities. The first comprehensive study of the problem of radioactive isotope release began in spring 1949 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Carlin
George Denis Patrick Carlin (May 12, 1937 – June 22, 2008) was an American comedian, actor, author, and social critic. Regarded as one of the most important and influential stand-up comedians of all time, he was dubbed "the dean of counterculture comedians". He was known for his black comedy and reflections on politics, the English language, psychology, religion, and taboo subjects. His "seven dirty words" routine was central to the 1978 United States Supreme Court case '' F.C.C. v. Pacifica Foundation'', in which a 5–4 decision affirmed the government's power to censor indecent material on public airwaves. The first of Carlin's 14 stand-up comedy specials for HBO was filmed in 1977. From the late 1980s onwards, his routines focused on sociocultural criticism of American society. He often commented on American political issues and satirized American culture. He was a frequent performer and guest host on ''The Tonight Show'' during the three-decade Johnny Carson era and ...

Doublespeak
Doublespeak is language that deliberately obscures, disguises, distorts, or reverses the meaning of words. Doublespeak may take the form of euphemisms (e.g., "downsizing" for layoffs and "servicing the target" for bombing), in which case it is primarily meant to make the truth sound more palatable. It may also refer to intentional ambiguity in language or to actual inversions of meaning. In such cases, doublespeak disguises the nature of the truth. Doublespeak is most closely associated with political language. Origins and concepts The term "doublespeak" derives from two concepts in George Orwell's novel ''Nineteen Eighty-Four'', "doublethink" and "Newspeak", though the term is not used in the book. Another variant, "doubletalk", also referring to deliberately ambiguous speech, did exist at the time Orwell wrote his book, but the usage of "doublespeak", as well as of "doubletalk", in the sense emphasizing ambiguity clearly postdates the publication of ''Nineteen Eighty-Four ...

Becquerel
The becquerel (; symbol: Bq) is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. For applications relating to human health this is a small quantity, and SI multiples of the unit are commonly used. The becquerel is named after Henri Becquerel, who shared a Nobel Prize in Physics with Pierre and Marie Skłodowska Curie in 1903 for their work in discovering radioactivity. Definition 1 Bq = 1 s−1 A special name was introduced for the reciprocal second (s−1) to represent radioactivity to avoid potentially dangerous mistakes with prefixes. For example, 1 µs−1 would mean 106 disintegrations per second: 1·(10−6 s)−1 = 106 s−1, whereas 1 µBq would mean 1 disintegration per 1 million seconds. Other names considered were hertz (Hz), a special name already in use for the reciprocal second, and Four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
