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:
“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)
“...I am who I am because I’m a black female.... When I was health director in Arkansas ... I could talk about teen-age pregnancy, about poverty, ignorance and enslavement and how the white power structure had imposed it—only because I was a black female. I mean, black people would have eaten up a white male who said what I did.”
—Joycelyn Elders (b. 1933)
“To speak or do anything that shall concern mankind, one must speak and act as if well, or from that grain of health which he has left.”
—Henry David Thoreau (1817–1862)
