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:
“Nothing in Nature’s sober found,
But an eternal health goes round.
Fill up the bowl, then, fill it high,
Fill all the glasses there—for why
Should every creature drink but I?
Why, man of morals, tell me why?”
—Abraham Cowley (1618–1667)
“Of all natural forces, vitality is the incommunicable one.... Vitality never “takes.” You have it or you haven’t it, like health or brown eyes or a baritone voice.”
—F. Scott Fitzgerald (1896–1940)
“I would hope that parents and grown children could be friends. When a friend confides in you that she’s going to do something that you think is most inappropriate, foolhardy or even dangerous, wouldn’t you as a friend say so—in a calm, supportive way? Yet I have to be so careful what I say to my children. I have to walk on eggs to be sure I’m not hurting their feelings or interfering with their lives.”
—Anonymous Parent of Adult Children. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 5 (1978)
