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)
“A comfortable house is a great source of happiness. It ranks immediately after health and a good conscience.”
—Sydney Smith (1771–1845)
“We have to give ourselves—men in particular—permission to really be with and get to know our children. The premise is that taking care of kids can be a pain in the ass, and it is frustrating and agonizing, but also gratifying and enjoyable. When a little kid says, “I love you, Daddy,” or cries and you comfort her or him, life becomes a richer experience.”
—Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 3 (1978)
