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:
“While I am to crawl upon this Planet, I would willingly enjoy the health at least of an insect.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“You will hardly know who I am or what I mean,
But I shall be good health to you nevertheless,
And filter and fibre your blood.
Failing to fetch me at first keep encouraged,
Missing me one place search another,
I stop somewhere waiting for you.”
—Walt Whitman (1819–1892)
“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)
