📌 About This Tool
The Half-Life Calculator is an advanced scientific tool designed for precise calculation of radioactive decay processes. Utilizing the fundamental principles of nuclear physics, this calculator helps determine the remaining quantity of a radioactive substance after a specified period based on its half-life - the time required for half of the radioactive atoms to undergo decay.
This essential tool finds applications in various fields including nuclear medicine (calculating isotope effectiveness), archaeology (radiocarbon dating), environmental science (monitoring radioactive contamination), and nuclear energy management. Our calculator implements the exponential decay formula N(t) = N₀ × (1/2)^(t/t½) with high precision algorithms, ensuring laboratory-grade accuracy in results.
Whether you're a student learning nuclear physics, a researcher analyzing decay patterns, or a professional working with radioactive materials, this tool provides instant results without complex manual calculations. The intuitive interface makes it accessible for users at all knowledge levels while maintaining scientific rigor for professional applications.

❓ Frequently Asked Questions
Q1: What is half-life in simple terms?
A: Half-life is the time required for half of a radioactive substance to decay into other forms of matter/energy.
Q2: Can I use this for carbon dating?
A: Yes! For C-14 dating, use 5730 years as the half-life value.
Q3: What units should I use?
A: Use consistent time units throughout (years with years, seconds with seconds).
Q4: How accurate are the results?
A: Results are accurate to 10 decimal places, sufficient for most scientific applications.
Q5: Can I calculate half-life from remaining quantity?
A: This version calculates remaining quantity. We'll add reverse calculation in future updates.
