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:
“As they move into sharing parenting, men often are apprentices to women because they are not yet as skilled in child care. Mothers have to be willing to teach fathers—both by stepping in and showing and by stepping back and letting them learn.”
—Nancy Press Hawley. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 6 (1978)
“A little health now and again is the ailing person’s best remedy.”
—Friedrich Nietzsche (1844–1900)
“We are conscious of an animal in us, which awakens in proportion as our higher nature slumbers. It is reptile and sensual, and perhaps cannot be wholly expelled; like the worms which, even in life and health, occupy our bodies. Possibly we may withdraw from it, but never change its nature. I fear that it may enjoy a certain health of its own; that we may be well, yet not pure.”
—Henry David Thoreau (1817–1862)
