The table compares some properties of α\alphaα-radiation, β\betaβ-radiation, and γ\gammaγ-radiation.
Which row is correct?
| α\alphaα-radiation | β\betaβ-radiation | γ\gammaγ-radiation | |
|---|---|---|---|
| A | highly penetrating (requires thick lead) | neutral (no charge) | positively charged |
| B | stopped by a thin sheet of paper | negatively charged | highly penetrating (requires thick lead) |
| C | stopped by a thin sheet of paper | neutral (no charge) | stopped by a thin sheet of paper |
| D | highly penetrating (requires thick lead) | negatively charged | neutral (no charge) |
