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:
“We have two kinds of conference. One is that to which the office boy refers when he tells the applicant for a job that Mr. Blevitch is in conference. This means that Mr. Blevitch is in good health and reading the paper, but otherwise unoccupied. The other type of conference is bona fide in so far as it implies that three or four men are talking together in one room, and dont want to be disturbed.”
—Robert Benchley (18891945)
“A comfortable house is a great source of happiness. It ranks immediately after health and a good conscience.”
—Sydney Smith (17711845)
“Many women who used to be full-time mothers are discovering that outside work gives them friends, challenges, variety, money, independence; it makes them feel better about themselves, and therefore lets them be better parents.”
—Wendy Coppedge Sanford. Ourselves and Our Children, by Boston Womens Health Book Collective, introduction (1978)
