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 filth and noise of the crowded streets soon destroy the elasticity of health which belongs to the country boy.”
—Rutherford Birchard Hayes (18221893)
“The fact that the mental health establishment has equated separation with health, equated womens morality with soft-heartedness, and placed mothers on the psychological hot seat has taken a toll on modern mothers.”
—Ron Taffel (20th century)
“Our young people are diseased with the theological problems of original sin, origin of evil, predestination, and the like. These never presented a practical difficulty to any man,never darkened across any mans road, who did not go out of his way to seek them. These are the souls mumps, and measles, and whooping- coughs, and those who have not caught them cannot describe their health or prescribe a cure. A simple mind will not know these enemies.”
—Ralph Waldo Emerson (18031882)
