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:
“The sick man is taken away by the institution that takes charge not of the individual, but of his illness, an isolated object transformed or eliminated by technicians devoted to the defense of health the way others are attached to the defense of law and order or tidiness.”
—Michel de Certeau (1925–1986)
“I think that carrying a baby inside of you is like running as fast as you can. It feels like finally letting go and filling yourself up to the widest limits.”
—Anonymous Mother. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 2 (1978)
“The middle years of parenthood are characterized by ambiguity. Our kids are no longer helpless, but neither are they independent. We are still active parents but we have more time now to concentrate on our personal needs. Our children’s world has expanded. It is not enclosed within a kind of magic dotted line drawn by us. Although we are still the most important adults in their lives, we are no longer the only significant adults.”
—Ruth Davidson Bell. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 3 (1978)
