1) Alpha radiation
2) Beta radiation
3) Gamma radiation
4) X-ray radiation

Answer 1

Gamma radiation is the type of radiation commonly used to sterilize materials such as plastic Petri dishes.

Step-by-step explanation:

The type of radiation that is commonly used to sterilize materials such as plastic Petri dishes is gamma radiation. Gamma radiation is extremely high-frequency electromagnetic waves and is the most penetrating type of nuclear radiation. It can easily penetrate paper and plastic, making it suitable for sterilizing packaged materials.
