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:
“A woman’s health is her capital.”
—Harriet Beecher Stowe (1811–1896)
“Publicity in women is detestable. Anonymity runs in their blood. The desire to be veiled still possesses them. They are not even now as concerned about the health of their fame as men are, and, speaking generally, will pass a tombstone or a signpost without feeling an irresistible desire to cut their names on it.”
—Virginia Woolf (1882–1941)
“In health of mind and body, men should see with their own eyes, hear and speak without trumpets, walk on their feet, not on wheels, and work and war with their arms, not with engine-beams, nor rifles warranted to kill twenty men at a shot before you can see them.”
—John Ruskin (1819–1900)
