What are the properties of the 3 types of radiation?
Properties of Alpha, Beta, and Gamma Radiation: Speed and Energy
| Average Energy | Speed | |
|---|---|---|
| Alpha | 5MeV | 15,000,000m/s |
| Beta | High (varies hugely) | close to speed of light |
| Gamma | Very high (again, varies hugely) | 300,000,000m/s |
Does alpha beta and gamma emit light?
Gamma rays (γ) are weightless packets of energy called photons. Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy. Gamma rays are similar to visible light, but have much higher energy. Gamma rays are often emitted along with alpha or beta particles during radioactive decay.
What are the differences between alpha beta and gamma rays?
Alpha particles carry a positive charge, beta particles carry a negative charge, and gamma rays are neutral. An alpha particle is made up of two protons and two neutrons bound together. Beta particles are high energy electrons. Gamma rays are waves of electromagnetic energy, or photons.
What is properties of gamma rays?

What are the different properties of alpha beta and gamma?
Alpha and beta radiation are types of radiation made out of particles. Alpha radiation has a high power of ionisation but low penetration. Beta radiation has a low power of ionisation but high penetration. Gamma radiation is a low-ionising, highly penetrating wave-like radiation.
What are the properties of gamma rays?
Properties of Gamma rays
- are electromagnetic waves of short wavelength and high frequency.
- They travel with velocity of light and are not charged particles like alpha or beta rays.
- They produce fluorescence effect on a photographic plate.
- They ionize gas they travel through but the ionization produced is very small.
