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:
“No one ever promised me it would be easy and it’s not. But I also get many rewards from seeing my children grow, make strong decisions for themselves, and set out on their own as independent, strong, likeable human beings. And I like who I am becoming, too. Having teenagers has made me more human, more flexible, more humble, more questioning—and, finally it’s given me a better sense of humor!”
—Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 4 (1978)
“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)
“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)
