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:
“To be stupid and selfish and to have good health are the three requirements for happiness, though if stupidity is lacking, the others are useless.”
—Gustave Flaubert (1821–1880)
“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)
“... work is only part of a man’s life; play, family, church, individual and group contacts, educational opportunities, the intelligent exercise of citizenship, all play a part in a well-rounded life. Workers are men and women with potentialities for mental and spiritual development as well as for physical health. We are paying the price today of having too long sidestepped all that this means to the mental, moral, and spiritual health of our nation.”
—Mary Barnett Gilson (1877–?)
