When Radiation burns which cause delayed irreversible changes of the skin can be caused by high doses of what form of ionizing radiation?

Radiation burns that lead to delayed irreversible changes in the skin can be caused by high doses of gamma rays and X-rays, both of which are forms of ionizing radiation. These types of radiation penetrate deeply into tissues, causing cellular damage and necrosis over time. This damage may not become apparent until weeks or months after exposure, resulting in complications such as fibrosis, ulceration, or skin cancer. Proper shielding and exposure limits are essential to prevent such injuries in clinical and industrial settings.
