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 health of the soul is something we can be no more sure of than that of the body; and though a man may seem far from the passions, yet he is in as much danger of falling into them as one in a perfect state of health of having a fit of sickness.”
—François, Duc De La Rochefoucauld (1613–1680)
“Every violation of truth is not only a sort of suicide in the liar, but is a stab at the health of human society.”
—Ralph Waldo Emerson (1803–1882)
“Pardon me, you are not engaged to any one. When you do become engaged to some one, I, or your father, should his health permit him, will inform you of the fact. An engagement should come on a young girl as a surprise, pleasant or unpleasant, as the case may be. It is hardly a matter that she could be allowed to arrange for herself.”
—Oscar Wilde (1854–1900)
