Answer:
Gamma γ radiations has the highest penetrating power, of all the nuclear emissions.
Explanation:
The three major types of nuclear emissions are alpha (α), beta (β) and gamma radiations. Of all three, gamma (Υ) radiations have the highest penetrating power (only shielded by lead and concrete), owing to its lack of mass and charge.
It also has a low ionization power and so does not interact well with matter. IT has vast application in cancer treatment and sterilization mechanism.
