Gamma rays are bundles quanta of energy that have no charge or mass and can travel long distances through air up to several hundred meters , body tissue, and other materials. Finished, painted, fire-resistance rated drywall assembly. Short wave ultraviolet light to nm is used to kill bacteria, hasten chemical reactions as a catalyst , and is also valuable in the identification of certain fluorescent minerals.
