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:
“The years when we are parenting teenagers are the high point, the crest when everything seems to be in bright colors and in ten-foot letters.”
—Jean Jacobs Speizer. Ourselves and Our Children, by Boston Women’s Health Collective, ch. 4 (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)
“The fact that the mental health establishment has equated separation with health, equated women’s morality with soft-heartedness, and placed mothers on the psychological hot seat has taken a toll on modern mothers.”
—Ron Taffel (20th century)
