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:
“Youth no less becomes
The light and careless livery that it wears
Than settled age his sables and his weeds,
Importing health and graveness.”
—William Shakespeare (15641616)
“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 Womens Health Collective, ch. 4 (1978)
“To be stupid and selfish and to have good health are the three requirements for happiness, though if stupidity is lacking, the others are useless.”
—Gustave Flaubert (18211880)
