Input Parameters

Calculation Results

Calculation Formula

Specific Activity (SA) = Activity (Bq) / Mass (g)

Where:
SA = Specific Activity (Becquerels per gram, Bq/g)
Activity = Total activity of the radioactive substance in Becquerels (Bq)
Mass = Mass of the radioactive substance in grams (g)

How to Use the Calculator

  1. Enter the total activity of the radioactive substance in Becquerels (Bq) in the "Activity" field.
  2. Enter the mass of the radioactive substance in grams (g) in the "Mass" field.
  3. Click the "Calculate" button to compute the specific activity.
  4. The result will be displayed in the "Specific Activity (Bq/g)" field.

Understanding Specific Activity

Specific activity is a measure of the radioactivity of a substance per unit mass. It is commonly used in nuclear physics and radiology to describe the activity of radioactive materials. The unit of specific activity is Becquerels per gram (Bq/g).

Example Calculation

Suppose you have a sample of a radioactive isotope with an activity of 5,000,000 Bq and a mass of 2.5 grams. The specific activity would be calculated as:

SA = 5,000,000 Bq / 2.5 g = 2,000,000 Bq/g

Applications

Specific activity is important in various fields including:

  • Nuclear medicine for radioisotope production and use
  • Environmental monitoring of radioactive contamination
  • Research in nuclear physics and chemistry
  • Quality control in industries using radioactive materials
