Health
Beta particles are able to penetrate living matter to a certain extent and can change the structure of struck molecules. In most cases such change can be considered as damage with results possibly as severe as cancer and death. If the struck molecule is DNA it can show a spontaneous mutation.
Beta sources can be used in radiation therapy to kill cancer cells.

Famous quotes containing the word health:
“The years when we are parenting teenagers are the high point, the crest when everything seems to be in bright colors and in ten-foot letters.”

“The debt was the most sacred obligation incurred during the war. It was by no means the largest in amount. We do not haggle with those who lent us money. We should not with those who gave health and blood and life. If doors are opened to fraud, contrive to close them. But dont deny the obligation, or scold at its performance.”
—Rutherford Birchard Hayes (18221893)
“You already know I desire that neither Father or Mother shall be in want of any comfort either in health or sickness while they live.”
—Abraham Lincoln (18091865)
