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:
“Woman ... cannot be content with health and agility: she must make exorbitant efforts to appear something that never could exist without a diligent perversion of nature. Is it too much to ask that women be spared the daily struggle for superhuman beauty in order to offer it to the caresses of a subhumanly ugly mate?”
—Germaine Greer (b. 1939)
“All health and success does me good, however far off and withdrawn it may appear; all disease and failure helps to make me sad and does me evil, however much sympathy it may have with me or I with it.”
—Henry David Thoreau (1817–1862)
“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)
