Strontium-147 cut into pieces what would be the half -life of each piece?

2.62 years

Explanation:

The half life of a material is the time taken for half of the number of radioactive atoms in a radioactive material to remain.

If a radioactive material is cut into pieces, each piece has the same half life as the whole material.

Hence, if Strontium-147 is cut into pieces, each piece will have a half life of 2.62 years, just as the whole material.
