Alpha (α\alphaα), beta (β\betaβ), and gamma (γ\gammaγ) radiations are emitted by radioactive sources.
Which statement about their properties is correct?
γ\gammaγ-radiation consists of electromagnetic waves and is the most penetrating radiation.
β\betaβ-radiation consists of uncharged particles and is the least highly ionising radiation.
α\alphaα-radiation consists of charged particles and is the most penetrating radiation.
γ\gammaγ-radiation consists of charged particles and is the most highly ionising radiation.
