A half-life calculator helps determine the time it takes for half of a radioactive substance to decay or for a substance in a chemical reaction to reduce by 50% of its original quantity. This tool is widely used in physics, chemistry, environmental studies, and pharmacology to analyze decay processes or drug clearance times.
How to Use the Half-Life Calculator
For Radioactive Decay
- Enter the initial quantity of the substance.
- Provide the remaining quantity after a specific time.
- Input the elapsed time.
- The calculator computes the half-life using the decay formula:
Half-Life (T₁/₂) = (t × log(2)) / log(Q₀ / Q)
Where:- Q₀ = Initial quantity
- Q = Remaining quantity
- t = Elapsed time
For Drug Clearance
- Input the initial drug concentration in the body.
- Provide the remaining concentration after a known time.
- Calculate to find the drug's half-life.
