Specific Activity of Isotope Solution

STEP 0: Pre-Calculation Summary

Formula Used

Specific Activity = (Activity*[Avaga-no])/Atomic Weight of Nuclide
A_s = (λ*[Avaga-no])/M
This formula uses 1 Constants, 3 Variables

Constants Used

[Avaga-no] - Avogadro’s number Value Taken As 6.02214076E+23

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.
Activity - (Measured in Becquerel) - Activity of Radioactive Substance is the Number of atoms disintegrated in unit time. It is also called as the rate of disintegration.
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

Activity: 0.0011 Disintegrations per Second --> 0.0011 Becquerel (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

A_s = (λ*[Avaga-no])/M --> (0.0011*[Avaga-no])/2.07567525023271E-25

Evaluating ... ...

A_s = 3.19142160376838E+45

STEP 3: Convert Result to Output's Unit

3.19142160376838E+45 Becquerel per Kilogram -->3.19142160376838E+42 Becquerel per Gram (Check conversion here)

FINAL ANSWER

3.19142160376838E+42 ≈ 3.2E+42 Becquerel per Gram <-- Specific Activity

FAQ

What is Specific Activity of Isotope?

Specific Activity of Isotope is defined as the concentration of radioactivity or the relationship between the mass of radioactive material and the activity and is represented as A_s = (λ*[Avaga-no])/M or Specific Activity = (Activity*[Avaga-no])/Atomic Weight of Nuclide. Activity of Radioactive Substance is the Number of atoms disintegrated in unit time. It is also called as the rate of disintegration & Atomic Weight of Nuclide is defined as the total number of protons and neutrons in the nucleus of an isotope of the nuclide.

How to calculate Specific Activity of Isotope?

Specific Activity of Isotope is defined as the concentration of radioactivity or the relationship between the mass of radioactive material and the activity is calculated using Specific Activity = (Activity*[Avaga-no])/Atomic Weight of Nuclide. To calculate Specific Activity of Isotope, you need Activity (λ) & Atomic Weight of Nuclide (M). With our tool, you need to enter the respective value for Activity & Atomic Weight of Nuclide and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Specific Activity?

In this formula, Specific Activity uses Activity & Atomic Weight of Nuclide. We can use 1 other way(s) to calculate the same, which is/are as follows -

Specific Activity = (0.693*[Avaga-no])/(Radioactive Half Life*Atomic Weight of Nuclide)
