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:
“In the continual enterprise of trying to guide appropriately, renegotiate with, listen to and just generally coexist with our teenage children, we ourselves are changed. We learn even more clearly what our base-line virtues are. We listen to our teenagers and change our minds about some things, stretching our own limits. We learn our own capacity for flexibility, firmness and endurance.”
—Jean Jacobs Speizer. Ourselves and Our Children, by Boston Women’s Health Collective, ch. 4 (1978)
“The philanthropist too often surrounds mankind with the remembrance of his own cast- off griefs as an atmosphere, and calls it sympathy. We should impart our courage, and not our despair, our health and ease, and not our disease, and take care that this does not spread by contagion.”
—Henry David Thoreau (1817–1862)
“A major difference between witches and psychotherapists is that witches see the mental health of women as having important political consequences.”
—Naomi R. Goldenberg (b. 1947)
