a range of different sources can be used:
- A nuclear reactor
- An actinoid such as californium which emits neutrons through spontaneous fission
- An alpha source such as radium or americium, mixed with beryllium; this generates neutrons by a (α,12C+n) reaction

Famous quotes containing the word sources:
“Even healthy families need outside sources of moral guidance to keep those tensions from imploding—and this means, among other things, a public philosophy of gender equality and concern for child welfare. When instead the larger culture aggrandizes wife beaters, degrades women or nods approvingly at child slappers, the family gets a little more dangerous for everyone, and so, inevitably, does the larger world.”
—Barbara Ehrenreich (20th century)
