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:
“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)
“To thee, fair Freedom! I retire
From flattery, cards, and dice, and din:
Nor art thou found in mansions higher
Than the low cot, or humble inn.
‘Tis here with boundless pow’r I reign;
And ev’ry health which I begin
Converts dull port to bright champagne;
Such Freedom crowns it, at an inn.”
—William Shenstone (1714–1763)
“To speak or do anything that shall concern mankind, one must speak and act as if well, or from that grain of health which he has left.”
—Henry David Thoreau (1817–1862)
