Radiation can be categorized into several types, including alpha, beta, and gamma radiation. Here’s a brief overview of each type:
### Alpha Radiation (α)
- **Composition**: Alpha particles consist of two protons and two neutrons (essentially a helium nucleus).
- **Charge**: Positively charged.
- **Mass**: Heaviest of the common radiation types.
- **Penetration Power**: Low; alpha particles can be stopped by a sheet of paper or the outer layer of human skin.
- **Biological Impact**: Alpha radiation is most dangerous when alpha-emitting materials are ingested or inhaled, as they can cause significant damage to internal tissues.
### Beta Radiation (β)
- **Composition**: Beta particles are high-energy, high-speed electrons (beta-minus) or positrons (beta-plus).
- **Charge**: Beta-minus particles are negatively charged, while beta-plus particles are positively charged.
- **Mass**: Lighter than alpha particles, but heavier than gamma rays.
- **Penetration Power**: Moderate; can penetrate paper but are usually stopped by a few millimeters of plastic or a few centimeters of air.
- **Biological Impact**: Beta radiation can cause damage to skin and internal organs, particularly if materials emitting beta radiation are ingested or absorbed.
### Gamma Radiation (γ)
- **Composition**: Gamma rays are electromagnetic waves (photons) with high energy.
- **Charge**: Neutral (no charge).
- **Mass**: Massless.
- **Penetration Power**: High; gamma rays can penetrate most materials, requiring dense materials like lead or several centimeters of concrete for shielding.
- **Biological Impact**: Gamma radiation can affect both external and internal tissues, potentially leading to cancer and other health issues due to its deep penetration and ability to ionize atoms in biological tissues.
### Summary
- **Alpha Radiation**: Heavy and charged, low penetration; harmful when ingested/inhaled.
- **Beta Radiation**: Lighter, charged, moderate penetration; can cause skin and internal damage.
- **Gamma Radiation**: Massless and neutral, high penetration; poses risks from both external and internal exposure.
