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:
“Most days I feel like an acrobat high above a crowd out of which my own parents, my in-laws, potential employers, phantoms of “other women who do it” and a thousand faceless eyes stare up.”
—Anonymous Mother. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 2 (1978)
“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)
“It is unconscionable that we ration health care by the ability to pay.... your heart breaks. Health care should be a given.”
—Kathryn Anastos (b. 1950)
