Radioactive Decay Calculator is a free online tool that displays the half life of the given isotope. BYJU’S online radioactive decay calculator tool makes the calculation faster and it displays the radioactive decay of the isotope in a fraction of seconds.

How to Use the Radioactive Decay Calculator?

The procedure to use the radioactive decay calculator is as follows:

Step 1: Enter the isotope in the input field

Step 2: Now click the button “Calculate Half Life” to get the result

Step 3: Finally, the radioactive decay of the given isotope will be displayed in the new window

What is Meant by Radioactive Decay?

In Physics, the radioactive decay is defined as the spontaneous breakdown of the nucleus, which results in the release of energy and also the matter from the atomic nucleus. It is noted that the radio-isotopes do not have enough binding energy to hold the nucleus in the atom. It means that the radio-isotopes have unstable nuclei. During the radioactive decay, the atomic nucleus becomes unstable, and there occurs the imbalance in the proton and neutron number.
