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:
“No one ever promised me it would be easy and it’s not. But I also get many rewards from seeing my children grow, make strong decisions for themselves, and set out on their own as independent, strong, likeable human beings. And I like who I am becoming, too. Having teenagers has made me more human, more flexible, more humble, more questioning—and, finally it’s given me a better sense of humor!”
—Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 4 (1978)
“The ideal of men and women sharing equally in parenting and working is a vision still. What would it be like if women and men were less different from each other, if our worlds were not so foreign? A male friend who shares daily parenting told me that he knows at his very core what his wife’s loving for their daughter feels like, and that this knowing creates a stronger bond between them.”
—Anonymous Mother. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 6 (1978)
“The filth and noise of the crowded streets soon destroy the elasticity of health which belongs to the country boy.”
—Rutherford Birchard Hayes (1822–1893)
