What form of ionizing radiation is known to cause radiation burns with delayed, irreversible changes of the skin?

Beta radiation is known to cause radiation burns with delayed, irreversible changes to the skin due to its ability to penetrate the outer layers of tissue. When beta particles, which are high-energy, short-range electrons or positrons, come into contact with the skin, they can deposit energy in biological tissues, leading to localized ionization and subsequent cellular damage. This can result in symptoms such as redness, blistering, and in severe cases, chronic skin injuries or ulcerative lesions, which characterize beta burns.

Beta radiation typically penetrates further than alpha particles but is less penetrating than gamma rays and X-rays, making it particularly damaging to the skin and superficial tissues when there is direct exposure. Understanding the different types of radiation and their effects is crucial for medical personnel and first responders when assessing radiation exposure and managing burn injuries.
