how does radiation cause immunosuppression?

Damaging DNA: Radiation damages DNA. For muscle, bone, or other long-lived cells, the cell may ignore the damage unless it is critical. For cells that are short lived or rapidly-dividing, like immune cells, the cell senses the damage and either commits cell-suicide or stops all its functions. Thus radiation prevents immune cell activation plus the production of new immune cells. Ask your doctor for more info.
