Comparison between α rays and γ rays based on charge, penetrating power, and ionising power:
| Property | α Rays (Alpha Rays) | γ Rays (Gamma Rays) |
|---|---|---|
| Charge | Positive charge (+2) | No charge (neutral) |
| Penetrating Power | Low penetration, stopped by a sheet of paper or skin | High penetration, can pass through thick materials like concrete and lead |
| Ionising Power | High ionising power, can ionize atoms effectively | Low ionising power, but can still ionize atoms over long distances |
