Arrange radioactive radiation in the increasing order of penetrating power.

Explanation

To arrange radioactive radiation in the increasing order of penetrating power, we need to understand the nature of the three types of radiation: alpha, beta, and gamma.

### Step-by-Step Solution:

1. **Identify the Types of Radiation**:
- **Alpha Radiation**: Composed of 2 protons and 2 neutrons (essentially a helium nucleus). It has a relatively large mass and a positive charge.
- **Beta Radiation**: Consists of high-energy, high-speed electrons (or positrons) emitted from a nucleus. It has a smaller mass compared to alpha particles.
- **Gamma Radiation**: A form of electromagnetic radiation (like light) with no mass and no charge. It is pure energy.
