Which type of radiation is most dangerous?

It depends on exposure type. Alpha is most damaging internally (if inhaled/swallowed) because it deposits all its energy locally. Gamma is most dangerous externally because it penetrates the body. Protection strategies differ accordingly.

Types of Radiation

Alpha, Beta, Gamma, X-rays

Learn About Radiation

Radiation comes in several forms, each with different properties and penetrating abilities. 理解する these differences is essential for radiation protection and medical applications.

Penetrating Power

Type	Stopped By	Danger
Alpha	Paper, skin	Internal if inhaled/ingested
Beta	Aluminum, glass	Skin burns, internal hazard
Gamma	Lead, thick concrete	Whole-body external hazard
Neutron	Water, polyethylene	Highly penetrating

まとめ

Different radiation types require different shielding. Alpha particles are easily stopped but dangerous if ingested. Beta penetrates further but aluminum stops it. Gamma and X-rays require dense materials like lead. 理解する these properties guides protection strategies.
