**Solving Continuous Decay Problems when given a half**

Isotope Decay Rate (Half-Life) Each radionuclide decays at its own unique rate which cannot be altered by any chemical or physical process. A useful measure of this rate is the half-life of the radionuclide. Half-life is defined as the time required for the activity of any particular radionuclide to decrease to one-half of its initial value. In other words one-half of the atoms have reverted... Solving Continuous Decay Problems when given a half-life. These techniques give you the most accurate answers for problems involving population growth, radioactive decay or anywhere you find the word “continuous” or “continuously.” 1. Begin with the formula: a=pe rt 2. Find the rate: No matter what your starting amount is, a half-life is the amount of time it takes until half of that

**decay rate and half life problem? Yahoo Answers**

So, all we need to know to find half life is the speed of a decay #K#. It can be determined experimentally for most practical situations since it depends on inner physical and chemical characteristics of a …... Half-life is the amount of time needed for one half of a given quantity of a substance to decay. Half-lives as short as 10 –6 second and as long as 10 9 years are common.

## How To Find Rate Of Decay Given Half Life

18/04/2010 · The decay rate of phosphorus-32 is 4.85% per day. What is its half-life?

- Radioactivity has a very definite mathematical description which allows the rate of decay to be calculated. The population of radioactive nuclei, N, is given by the mathematical expression:
- Practice calculating the radioactive decay. Radium-226 has a half-life of 1,600 years. Calculate the activity of a one gram sample, where N = 2.66 x 10 exp(21).
- Isotope Decay Rate (Half-Life) Each radionuclide decays at its own unique rate which cannot be altered by any chemical or physical process. A useful measure of this rate is the half-life of the radionuclide. Half-life is defined as the time required for the activity of any particular radionuclide to decrease to one-half of its initial value. In other words one-half of the atoms have reverted
- We try here to calculate the general law for decay. We have an initial population #Q_i# and, after a time interval #\Delta t# we have a new population, #Q_f#, that was the initial population times the constant of decay (that we can call #lambda#).
