A radioactive decay calculator helps determine the remaining quantity of a radioactive substance over time. It is based on the half-life of isotopes, which is the time required for half of the substance to decay. This tool is essential for nuclear physics, environmental studies, and radiopharmaceutical research.
How to Use the Radioactive Decay Calculator
Step 1: Enter Initial Quantity
Provide the starting amount of the radioactive material (in grams, moles, or units of activity).
Step 2: Specify Half-Life
Input the half-life of the isotope (in seconds, minutes, hours, or years).
Step 3: Enter Time Elapsed
Specify the time period for which you want to calculate the remaining substance.
Step 4: Calculate
The tool uses the decay formula:
N = N₀ × e^(-λt)
Where:
- N = Remaining quantity
- N₀ = Initial quantity
- λ = Decay constant ()
- t = Time elapsed
Example Calculation
If 100 g of a substance with a half-life of 5 years is analyzed after 15 years, the remaining quantity would be approximately 12.5 g.
