Answer 2

The correct answer is option D) All of the above.

Gamma radiation is a stream of highly energetic gamma particles that can easily penetrate most of the compounds. It is a result of unstable atoms that are trying to stabilize. The excess energy is released as gamma particles. However, lead, steel and concrete reduce the energy of these particles and hence stop their penetrating abilities.
