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:
“... work is only part of a mans life; play, family, church, individual and group contacts, educational opportunities, the intelligent exercise of citizenship, all play a part in a well-rounded life. Workers are men and women with potentialities for mental and spiritual development as well as for physical health. We are paying the price today of having too long sidestepped all that this means to the mental, moral, and spiritual health of our nation.”
—Mary Barnett Gilson (1877?)
“We have to give ourselvesmen in particularpermission to really be with and get to know our children. The premise is that taking care of kids can be a pain in the ass, and it is frustrating and agonizing, but also gratifying and enjoyable. When a little kid says, I love you, Daddy, or cries and you comfort her or him, life becomes a richer experience.”
—Anonymous Father. Ourselves and Our Children, by Boston Womens Health Book Collective, ch. 3 (1978)
“Nothing in Natures sober found,
But an eternal health goes round.
Fill up the bowl, then, fill it high,
Fill all the glasses therefor why
Should every creature drink but I?
Why, man of morals, tell me why?”
—Abraham Cowley (16181667)
