What is a radioactive decay chain?

A radioactive decay chain, also known as a nuclear decay chain, is a series of radioactive decays where an unstable atomic species undergoes a transformation, turning into different atoms until a stable one is formed. This decay process happens through alpha (α) or beta (β) emission, resulting in the creation of different isotopes until a stable nuclide is achieved. For instance, the uranium-238 decay chain includes 14 sequential decays, resulting in lead-206, a stable isotope.

Why are radioactive decay chains important?

Understanding radioactive decay chains is crucial for various scientific fields. In nuclear physics, decay chains explain how unstable isotopes undergo transmutation, providing insights into nuclear stability and energy production in stars. In geology and archaeology, decay chains are fundamental in radiometric dating techniques, helping to determine the age of rocks and artifacts. In climate science, they play a vital role in studying past climate changes through ice cores and sediment layers.

Radioactive decay formula

To calculate the remaining atoms after a specific period in a decay chain, we use the formula:

N(t) = N₀ * e^-λt

• N(t) - Represents the number of atoms at time 't'
• N0 - Denotes the initial number of atoms
• λ - Is the decay constant, calculated as ln(2) / half-life
• t - Stands for the time elapsed

How to use our Radioactive Decay Chain Calculator

Our calculator provides a user-friendly way to calculate remaining atoms over time in a decay chain. Here's how to use it:

• Number of atoms - Enter the initial number of atoms in this field.
• Half-life - Input the half-life of the isotope.
• Time - Fill in the elapsed time.
• Calculate - Click this button to calculate the remaining number of atoms.

Example of a decay chain calculation

Let's take a practical example. Suppose you have a sample of 1000 uranium-238 atoms, which has a half-life of 4.468 billion years. You want to know the remaining atoms after 1 billion years. Just input these values into the respective fields and click 'Calculate'. The result will be the number of uranium-238 atoms remaining after 1 billion years.
