Half Life Calculator

Description

⏳ Half-Life Calculator – Calculate Radioactive Decay and Time-Based Substance Reduction

The Half-Life Calculator is a powerful and intuitive tool designed to calculate the decay of radioactive elements, the remaining quantity of a substance over time, or the time required for decay, using the half-life principle. Whether you're a student, scientist, or engineer, this calculator provides fast, accurate results for understanding exponential decay in physics, chemistry, pharmacology, and more.

🔹 What Is Half-Life?

Half-life is the time it takes for half of a radioactive substance to decay or for half of a chemical/drug to be eliminated. This calculator solves the key equation:

N(t) = N₀ × (1/2)^(t / t½)
Where:

• N(t) is the remaining quantity

• N₀ is the initial quantity

• t is time elapsed

• t½ is the half-life

🧮 What You Can Calculate:

• Remaining amount (N) after a given time

• Elapsed time (t) needed for a substance to decay to a known amount

• Half-life (t½) if the initial and remaining amounts and time are known

✅ Features:

• 📊 Flexible Input: Use any units (seconds, minutes, years, etc.)

• 🔁 Reverse Calculation: Solve for time, half-life, or amount

• 🧪 Common Isotope Data: Built-in list of half-lives for common radioactive elements like Carbon-14, Uranium-238, Iodine-131, etc. (optional)

• 💊 Pharmacokinetics Mode: Estimate drug concentration over time

• 📉 Decay Graph: Visual representation of decay over time (if supported)

• 📜 Step-by-Step Solution: Ideal for students learning decay equations

🎓 Ideal For:

• Students & Teachers: Learning or demonstrating nuclear decay in physics or chemistry

• Researchers: Working on isotopic analysis or radioactive dating

• Medical Professionals: Estimating drug metabolism or radioactive tracer clearance

• Pharmacologists: Modeling how a drug’s concentration reduces with time

• Environmental Scientists: Studying radioactive contamination or decay in ecosystems

💡 Example Scenarios:

• How much of a 200g Carbon-14 sample remains after 11,460 years?

• How long does it take for a radioactive isotope to decay from 100g to 12.5g?

• What is the half-life of a substance that decays from 500mg to 250mg in 6 hours?

Whether you're modeling nuclear decay, drug clearance, or exponential loss, the Half-Life Calculator gives you precise and insightful answers in seconds. With flexible input options and educational support, it’s an essential tool for any scientist, student, or curious mind exploring the world of decay and transformation.
