Calculate Corrected Activity





Formula

The formula to calculate the corrected activity of a radioactive substance is:

\[ A = A_0 \times \left(\frac{1}{2}\right)^{\frac{t}{T}} \]

What is Decay Correction?

Decay correction is a process used to calculate the remaining activity of a radioactive substance after a certain period of time has passed. It accounts for the exponential decrease in activity due to the decay of radioactive isotopes. This calculation is crucial in various fields such as nuclear medicine, radiopharmacy, and environmental monitoring to ensure accurate dosage, safety, and compliance with regulations.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ A = 100 \times \left(\frac{1}{2}\right)^{\frac{24}{6}} = 100 \times \left(\frac{1}{2}\right)^{4} = 100 \times 0.0625 = 6.25 \text{ MBq} \]

The Corrected Activity is 6.25 MBq.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ A = 200 \times \left(\frac{1}{2}\right)^{\frac{10}{3}} \approx 200 \times 0.0884 = 17.68 \text{ MBq} \]

The Corrected Activity is approximately 17.68 MBq.
