How does radiation cause cell death

WebWhen cells are damaged by harmful factors (such as injury or toxic chemicals), they usually “spill their guts” as they die. Because the damaged cell’s plasma membrane can no longer control the passage of ions and water, the cell swells up, and its contents leak out through holes in the plasma membrane. WebUltraviolet radiation from the sun can zap DNA, damage cells, and set the stage for the subsequent development of cancer. Scientists have now identified the built-in safety mechanism that forces some cells damaged by UV radiation to commit suicide so they do not perpetuate harmful mutations.
