What is the classification of radiation that can cause ionization in biological tissues?

The classification of radiation that can cause ionization in biological tissues includes several forms, one of which is beta particles. Beta particles are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei during radioactive decay. Because of their charge and energy, beta particles have sufficient energy to ionize atoms when they interact with biological tissues. This ionization can damage cellular structures, including DNA, potentially leading to various health effects.

Other forms of radiation listed in the choices, such as X-rays and gamma rays, are also capable of causing ionization. X-rays are a form of electromagnetic radiation that can penetrate tissues and cause ionization, thus contributing to biological effects. Gamma rays, which are also electromagnetic radiation but typically of higher energy than X-rays, have similar ionizing capabilities.

Ultraviolet rays, while they can cause damage to biological tissues and are classified as ionizing radiation, generally operate at a lower energy level compared to the other options and mainly affect the skin.

In summary, while beta particles are indeed able to cause ionization in biological tissues, it's essential to recognize that X-rays and gamma rays can also have this effect, making them relevant in the context of radiation's biological impact.
