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:
“To be stupid and selfish and to have good health are the three requirements for happiness, though if stupidity is lacking, the others are useless.”
—Gustave Flaubert (1821–1880)
“The first year was critical to my assessment of myself as a person. It forced me to realize that, like being married, having children is not an end in itself. You don’t at last arrive at being a parent and suddenly feel satisfied and joyful. It is a constantly reopening adventure.”
—Anonymous Mother. From the Boston Women’s Health Book Collection. Quoted in The Joys of Having a Child, by Bill and Gloria Adler (1993)
“However strongly they resist it, our kids have to learn that as adults we need the companionship and love of other adults. The more direct we are about our needs, the easier it may be for our children to accept those needs. Their jealousy may come from a fear that if we adults love each other we might not have any left for them. We have to let them know that it’s a different kind of love.”
—Ruth Davidson Bell. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 3 (1978)
