11.   For example, different types of atoms are expected to emit radiation in different ways.

12.   If stars emitted radiation equally in all wavelengths, this effect would indeed be cancelled out by other radiation redshifted into the visible range.

13.   In an effort to reassure cell phone users, the cell phone industry announced Tuesday that new cell phones will carry labels describing how much microwave radiation they emit.

14.   Low-frequency electric and magnetic radiation is emitted by all kinds of everyday electrical conductors, from appliances and household wiring to high-energy transmission lines.

15.   Objects emit radiation of increasing frequency as they get hotter, which is why a filament goes from red-hot to blue-hot when it heats up.

16.   Removed from shielding, they weigh a few pounds, but would emit enough radiation to kill a terrorist before he could attach it to conventional explosives.

17.   Storage of plutonium, which emits radiation for tens of thousands of years, also can be problematic, Goodhope said.

18.   The array can thus produce detailed images of objects emitting radiation in radio wavelengths.

19.   The look is topped by an outcropping of platinum hair so artificially bright that it just may emit low-level radiation.

20.   Their findings led to the development of the maser, a device that emits microwave radiation of a single wavelength.
