Lower ionization potential
- Thus, beta particles have greater penetration depth but lower ionization potential than alpha particles.

Feb 10, 2011 · Alpha particles are the nuclei of He, i.e. lacking the two electrons they carry a charge of $+2e$, while beta particles are either electrons or positrons and thus carrying a charge of $\mp 1e$. Positrons meeting other atoms' electrons annihilate thus leaving a positive ionization.
Mar 25, 2024 · Qualitatively compare the ionizing and penetration power of alpha particles (α), beta particles (β), and gamma rays (γ). Describe the biological impact of ionizing radiation. Know the most common source of background radiation and how to minimize exposure to this source.
In beta-plus decay, a proton is converted into a neutron, and a positron (positively charged beta particle) and a neutrino are emitted. Due to their smaller mass and charge, beta particles have a higher ionizing potential compared to alpha particles.
Beta particles are much smaller than alpha particles and therefore, have much less ionizing power (less ability to damage tissue), but their small size gives them much greater penetration power. Most resources say that beta particles can be stopped by a one-quarter inch thick sheet of aluminum.

Mar 20, 2020 · In general, beta particles are lighter than alpha particles, and they generally have a greater ability to penetrate other materials. As a result, these particles can travel a few feet in the air, and can penetrate skin.

As charged particles, alpha and beta particles ionize other molecules through remarkably strong Coulombic forces. Gamma particles, meanwhile, interact through the photoelectric effect, which can still ionize but have a much lower potential. Penetration Depth of Radioactive Particles.
