What is the specific activity (in Bq/g) if 8.58 mg of an isotope emits 7.4x10⁴ α particles per minute?
Monica [59]

Specific activity is the activity per unit mass of a radionuclide and is a physical property of that radionuclide. Activity is a quantity (for which the SI unit is the becquerel) related to radioactivity, and is defined as the number of radioactive transformations per second that occur in a particular radionuclide.

<h3>How do you find the specific activity of an isotopes?</h3>

  •       Activity = λN.
  •       = (0.693/8 days) x (1/86,400 sec/day) x (3 x 1017 atoms)
  •       = 3 x 1011 atoms/sec I-131.
  •       = 3 x 1011 dps I-131.

<h3>What is the specific activity of Co 60?</h3>

The average specific activity of 60Co in continental aquatic sediments is in the region of 1 Bq. kg-1 dry weight (Eyrolle et al., 2008). Cobalt distribution in the abiotic compartments of continental aquatic systems is characterised by the strong affinity of the element for sediment.
