How Does Alpha Radiation Interact with Biological Tissues?
Alpha particles have a high mass and charge, which limits their ability to penetrate materials. They can be stopped by a sheet of paper or even the outer layer of human skin. However, if alpha-emitting substances are inhaled, ingested, or enter the body through a wound, they can cause significant damage to biological tissues. This is due to their high ionizing power, which can disrupt cellular structures and damage DNA.
