How to Convert Grams to Curies

Step-by-Step Guide

1. 1

   Step 1: Calculate the number of moles in the given amount of the radioactive material.

   This can be done by dividing the amount (in grams) by the atomic mass of the material.
2. 2

   Step 2: Calculate the number of atoms in the given amount of the radioactive material.

   This can be done by multiplying the number of moles by the Avogadro's Constant (6.022 × 1023). , It can be directly found in literature, or It can be calculated with the help of half-life (which is readily available in literature) thus:
   Decay Constant =
   0.693 / Half-life. (be sure to use half-life in seconds) ,,, The result is the amount of the radioactive material expressed in Ci (Curies)!
3. 3

   Step 3: Find the decay constant (in per second) of the radioactive material.

4. 4

   Step 4: Multiply the number of atoms by the decay constant to get the total amount of radiations (decays per second)

5. 5

   Step 5: Recall that 3.7 × 1010 decays per second equal 1 Ci

6. 6

   Step 6: Divide the amount of radiations (decays per second) by 3.7 × 1010.
