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.

Hence, if Strontium-147 is cut into pieces, each piece will have a half life of 2.62 years, just as the whole material.
If it causes danger to an individual, if you're going to sacrifice someone, or if it causes a conflict with other established laws.
