| Our radio and television broadcasts have been leaking into space since the 1930s, when the first powerful emitters were constructed. |
| By 1963, the year of my parent's marriage, the average release of beta emitters from reactor effluent was 14, 500 curies per day. |
| This is done by placing different emitters in the soil next to the foundation, below the basement floor, and in the house. |
| The rear and front surfaces of an object are covered with a material containing an array of photodetectors and light emitters respectively. |
| It consisted of a movable frame with embedded light emitters and detectors around its perimeter. |
| Second, it was established that cyan and green emitters can be modified so as to produce an intermediate spectrum of fluorescence. |
