Are x-rays more or less penetrating than charged alpha or beta particles?

X-rays are indeed more penetrating than charged alpha or beta particles. The key reason lies in the nature of radiation and its interactions with matter. X-rays are electromagnetic radiation, which has high energy and a shorter wavelength compared to the particulate radiation emitted by alpha and beta particles.

Alpha particles, being positively charged and relatively heavy, consist of two protons and two neutrons. Their mass and charge lead them to interact more readily with matter, losing their energy quickly over short distances. Consequently, alpha particles are easily absorbed by materials such as paper or even the outer layer of human skin.

Beta particles, which are electrons or positrons, are lighter than alpha particles but still carry a charge. They can penetrate materials better than alpha particles, but they still have limitations due to their mass and charge, which results in ionization losses as they pass through matter.

X-rays, on the other hand, have no charge and are much less interactive with matter compared to charged particles. Their penetrating power allows them to pass through various materials, including human tissue, making them suitable for medical imaging. This characteristic of x-rays means they can travel through thicker and denser substances that would significantly attenuate alpha and beta particles.

Thus, the ability of x-rays to penetrate deeper
