half life teriminin İngilizce İngilizce sözlükte anlamı: 50% of the initial number of atoms of a radionuclide decay within one half life; the time it takes for 1/2 of a radioactive substance to decay Radiochemicals decay according to first order kinetics, so the half life is a constant; the time required for something to fall to half its initial value (in particular, the time for half the atoms in a radioactive substance to disintegrate); time taken for half of the reactants to be converted into products; The time during which a given amount of radioactivity will decay to half the amount; The amount of time it takes for half an initial amount to disintegrate; The time it takes certain materials, such as persistent pesticides, to become chemically altered; The half-life of a radioisotope is the time taken for half of the atoms in a sample of that radionuclide to decay (emit nuclear radiation) It can also be expressed as the time taken for the activity of the sample to halve It has the following accepted symbols; {i} amount of time it takes for half of the atoms in a radioactive substance to break down or decay; Point in time when the principal on a mortgage backed security (issued or guaranteed by the Government National Mortgage Association, the Federal National Mortgage Association, or the Federal Home Loan Mortgage Association) has been repaid It is presumed that the security has a half life of 12 years However, depending on interest rate trends, specific mortgage pools can have longer or shorter half lives If interest rates rise, homeowners will hold onto their mortgages longer than predicted, and half lives will rise If interest rates fall, more homeowners will refinance their mortgages Thus, principal will be paid off more quickly, and half lives will drop; The period of time required for half of a given quantity of an isotope to undergo radioactive decay; The time it takes for the blood level to decrease by half after a drug is stopped Therefore, if an AED which has a half life of 24 hours is stopped and the blood level at that time is 20, in 24 hours the level will decrease to 10 (The level then will decrease to 5 in 48 hours, 2 5 in 72 hours, 1 25 in 96 hours, etc ); In a chemical reaction, the time required for the concentration of a reactant to fall from a chosen value to half that value; The time it takes for a substance (drug, radioactive nuclide, or other) to lose half of its pharmacological, physiologic, or radiological activity; The time it takes for an idea or a fashion to lose half of its influential power
Most books of scholarship have surprisingly short intellectual 'half-lives during which they make a difference.; The time required for half of the nuclei in a sample of a specific isotope to undergo radioactive decay; {i} futuristic computer adventure game manufactured by Valve Software; the time required for one-half of a radioactive material to decay to a more stable material (it is NOT one-half the age of the rock!); The time it takes for half the atoms in an amount of nuclear waste to become harmless; The period required for half of the atoms of a particular radioactive isotope to decay and become an isotope of another element; The time required for half the amount of a drug to be eliminated from the body; the time required for the number of nuclides in a radioactive sample to reach half of the original value; The amount of time that it takes for one half of an original population of atoms of a radioactive isotope to decay; The time over which the atoms of a particular radioactive nuclide decay to half their original intensity of emitted radiation The half-life is a characteristic property of each radioactive isotope; The time required for half the nuclei in a sample of a specific isotopic species to undergo radioactive decay; The time necessary for half of the atoms of a parent isotope to decay into the daughter isotope; The time in which half the atoms of a radioactive substance will have disintegrated, leaving half the original amount Half the residue will disintegrate in another equal period of time; the time required for something to fall to half its initial value (in particular, the time for half the atoms in a radioactive substance to disintegrate); the time required for half of the amount of an agent (e g , drug, virus, cell type) to be eliminated from the body; The amount of time it takes half of a given quantity of a radioactive element to decay; The time required for the amount of a reactant to decrease to half its initial value; - The time required for half of any quantity of identical radioactive atoms to undergo radioactive decay, so that half of the atoms in the substance are no longer emitting radiation and are no longer considered to be radioactive; the time required for half the amount of a substance to be eliminated from the body or to be converted to another substance(s); The time that it takes for half of the activity of a molecule to decay; The time required for half of a reactant to be converted into product(s); The period of time it takes for half the nuclei of a radioactive element to undergo decay to another nuclear form; In the case of a unique process of radioactive disintegration, the average time needed for the activity of a radioactive source to be reduced to half of its initial value High-level waste Waste emitting heat produced by a high level of radioactivity (in particular spent fuel unloaded from nuclear reactors and considered as final waste, and vitrified waste resulting from reprocessing); the time required for a radioactive substance to lose half of its nuclei; the time required for half the amount of an agent (e g , drug, virus, cell type) to be eliminated from the body; The half-life of a radioactive substance is the amount of time that it takes to lose half its radioactivity. the length of time it takes a radioactive substance to lose half of its radioactivity.
