| Among the commonly known alpha emitters are various isotopes of polonium, radium, thorium, uranium and all of the transuranium elements. |
| Too little flow could be caused by a kink in the line or particles clogging the emitters. |
| The rear and front surfaces of an object are covered with a material containing an array of photodetectors and light emitters respectively. |
| In addition, a number of radioisotopes, both natural and man-made, have been identified as beta emitters. |
| By 1963, the year of my parent's marriage, the average release of beta emitters from reactor effluent was 14, 500 curies per day. |
| Our radio and television broadcasts have been leaking into space since the 1930s, when the first powerful emitters were constructed. |
