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:
“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)
“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)
“Plants are the young of the world, vessels of health and vigor; but they grope ever upwards towards consciousness; the trees are imperfect men, and seem to bemoan their imprisonment, rooted in the ground.”
—Ralph Waldo Emerson (1803–1882)
