Determination and Use of the Half-Life Example: What is the half-life of a radioisotope that has a rate constant of 0.225 d -1 ? Half-life (t 1/2 ) is the time for the radioisotope to reach 50% of its original amount.... The half life calculator can be used to calculate the remaining amount of anything such as radioactive decay or for drug calculations. Let's say, for instance, there is a drug that is given in a 10mg dose. It has a half life of 6 hours. This means that 6 hours later, half of the medication will be consumed, leaving half remaining, at 5mg. Then another 6 hours another half will be consumed

**Half-Life and Activity · Physics**

where y = fraction of original material . and . t1/2 = number of half-lives ∴, y 1 2. t. 1/2 = and . y 1 t. 1/2. log. 2 = to calculate the age (# years): t. age = (half-life) * t 1/2. t age = (half-life) * y 1 log 2. That’s really all there is to it . The equations really are that simple! The following pages have examples and explanations of how this simple form of the equation is the same... 21/11/2010 · after 3 days a sample of radon-222 has decayed to 58% of its original amount. Find its half life and find how long it will take to decay 20% of its original amount

The time interval required for an amount of certain radioactive nuclei to decay to its half of original value. Biological half-life time (T b ) The time interval required for the body to eliminate 50% of any substance by normal routes of elimination: metabolic turnover and excretion. how to find vehicle registration online After many more half-lives, a very small amount of the original parent isotope remains, and almost all of it has decayed into the daughter product. Each radioactive isotope has its own characteristic half-life.
