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)
“It is always singular, but encouraging, to meet with common sense in very old books, as the Heetopades of Veeshnoo Sarma; a playful wisdom which has eyes behind as well as before, and oversees itself. It asserts their health and independence of the experience of later times. This pledge of sanity cannot be spared in a book, that it sometimes pleasantly reflect upon itself.”
—Henry David Thoreau (1817–1862)
“... 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–?)
