1.   All matter at temperatures above that of absolute zero emits infrared radiation.

2.   But a body with a particular temperature must emit radiation at a certain rate.

3.   The Earth emits natural radiation.

4.   The lamps emit ultra-violet radiation which has powerful cancer-causing abilities, according to a small pilot study on its effects on mice.

5.   The lamps emit ultra-violet radiation.

6.   An X-ray beam focused on the surface of an object causes it to emit radiations that are analyzed by a detector.

7.   And plutonium is an enticing target for thieves, because it emits radiation at very low levels.

8.   Because noble gases do not react with other elements to form compounds, they both absorb and emit electromagnetic radiation in relatively simple ways.

9.   A group of auditors found last year that a forklift accident in the bunkers could slam several pits together until the plutonium has a chain reaction emitting lethal radiation.

10.   Every element has characteristic frequencies at which it absorbs and emits electromagnetic radiation.
