What is the half life period of tritium ?

Options

A. 13.33 year
B. 12.33 year
C. 12 years
D. 22.33 years

Answer

To find the half-life period of tritium, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Tritium**: Recognize that tritium is a radioactive isotope of hydrogen, denoted as \( ^3H \) or \( T \).

2. **Understand Half-Life**: The half-life of a radioactive substance is the time required for half of the radioactive atoms in a sample to decay.

3. **Research the Half-Life of Tritium**: Look up the known half-life of tritium. It is a well-documented fact that the half-life of tritium is approximately 12.33 years.

4. **Select the Correct Option**: Given the options provided in the question, identify which one matches the known half-life of tritium. The correct option is 12.33 years.

5. **Conclusion**: State that the half-life period of tritium is 12.33 years.

### Final Answer:
The half-life period of tritium is **12.33 years**.
