Three types of radiation are α\alphaα-radiation, β\betaβ-radiation, and γ\gammaγ-radiation.
Which statement is correct?
α\alphaα-radiation has a greater range in air than β\betaβ-radiation.
β\betaβ-radiation is more penetrating than γ\gammaγ-radiation.
α\alphaα-radiation is the most strongly ionising of the three types of radiation.
γ\gammaγ-radiation is more ionising than β\betaβ-radiation.
