Variables Used
Specific Activity - (Measured in Becquerel per Kilogram) - Specific Activity is defined as the concentration of the radioactivity or the relationship between the mass of radioactive material and the activity.
Radioactive Half Life - (Measured in Second) - Radioactive Half Life is defined as the time required for a quantity of radioactive substance to decay to half of it's initial value.
Atomic Weight of Nuclide - (Measured in Kilogram) - Atomic Weight of Nuclide is defined as the total number of protons and neutrons in the nucleus of an isotope of the nuclide.
STEP 1: Convert Input(s) to Base Unit
Radioactive Half Life: 0.0002 Year --> 6311.3904 Second (Check conversion ​here)
Atomic Weight of Nuclide: 125 Atomic Mass Unit --> 2.07567525023271E-25 Kilogram (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
As = (0.693*[Avaga-no])/(T1/2*M) --> (0.693*[Avaga-no])/(6311.3904*2.07567525023271E-25)
Evaluating ... ...

## What is Activity in Radioactive- Decay process?

Activity, in radioactive-decay processes, is the number of disintegrations per second, or the number of unstable atomic nuclei that decay per second in a given sample.Activity is determined by counting, with the aid of radiation detectors and electronic circuits, the number of particles and photons (pulses of electromagnetic energy) ejected from a radioactive material during a convenient time interval. This experimental count, however, must be interpreted in the light of a thorough knowledge of the particular manner of radioactive decay in the sample material, because some sources emit more than one particle or photon per disintegration.
