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:
“Some fear that if parents start listening to their own wants and needs they will neglect their children. It is our belief that children are in fact far less likely to be neglected when their parents’ needs—for support, for friendship, for decent work, for health care, for learning, for play, for time alone—are being met.”
—Wendy Coppedge Sanford. Ourselves and Our Children, by Boston Women’s Health Book Collective, introduction (1978)
“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)
“The same soil is good for men and for trees. A man’s health requires as many acres of meadow to his prospect as his farm does loads of muck.”
—Henry David Thoreau (1817–1862)
