(Gıda,Tıp) half life
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

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 )
