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:
“I hold it that a little rebellion, now and then, is a good thing, and as necessary in the political world as storms in the physical.... It is a medicine necessary for the sound health of government.”

“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 powr I reign;
And evry health which I begin
Converts dull port to bright champagne;
Such Freedom crowns it, at an inn.”
—William Shenstone (17141763)
