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:
“Self-esteem is as important to our well-being as legs are to a table. It is essential for physical and mental health and for happiness.”
—Louise Hart (20th century)
“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)
“I still need more healthy rest in order to work at my best. My health is the main capital I have and I want to administer it intelligently.”
—Ernest Hemingway (1899–1961)
