About

Radioactive decay is a fascinating and essential concept in nuclear physics and chemistry. It refers to the process by which unstable atomic nuclei lose energy by emitting radiation. This decay can occur in various forms, such as alpha decay, beta decay, and gamma decay. Understanding radioactive decay is critical for numerous applications, including nuclear medicine, archaeology, and environmental science.

The Radioactive Decay Calculator is a powerful tool that simplifies the process of calculating the remaining quantity of a radioactive substance after a given period of time. It can help researchers, students, and professionals in various fields perform complex calculations quickly and accurately.

How to Use

Using the radioactive decay calculator is straightforward. Follow these simple steps:

1. Input the initial quantity of the radioactive material.
2. Enter the decay constant or half-life of the substance.
3. Input the time period over which you want to calculate the decay.
4. Click the “Calculate” button to obtain the final amount of the substance remaining.

These steps are integral for anyone looking to carry out precise calculations regarding radioactive decay in both academic and practical applications.

Formula

The formula to calculate radioactive decay is:

N(t) = N0 * e^(-λt)

Where:

• N(t) = remaining quantity of radioactive material after time t
• N0 = initial quantity of radioactive material
• λ = decay constant (related to half-life)
• t = time elapsed

Understanding this formula is essential for accurate calculations and a clear grasp of how radioactive decay functions over time.

Example Calculation

Let’s consider an example for better understanding:

An initial quantity of 100 grams of Uranium-238 has a half-life of 4.468 billion years. Calculate the amount remaining after 10 billion years.

1. Determine the decay constant (λ) using the formula: λ = ln(2) / half-life. This gives us: λ = 0.154×10^-9 years^-1.
2. Plug the values into the decay formula: N(t) = N0 * e^(-λt).
3. After inserting: N(10) = 100 * e^(-0.154×10^-9 * 10)⁹ = 81.87 grams (approximately).

This example showcases how to apply the formula effectively for real-world scenarios.
