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 don’t want to be disturbed.”
—Robert Benchley (1889–1945)
“At last I feel the equal of my parents. Knowing you are going to have a child is like extending yourself in the world, setting up a tent and saying “Here I am, I am important.” Now that I’m going to have a child it’s like the balance is even. My hand is as rich as theirs, maybe for the first time. I am no longer just a child.”
—Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 5 (1978)
“Give a man health and a course to steer; and he’ll never stop to trouble about whether he’s happy or not.”
—George Bernard Shaw (1856–1950)
