| 31. | Since 1990 North American had produced precisely measured radiation sources for calibrating medical and industrial nuclear equipment.
|
| 32. | The radiation source serves to increase the reliability of ignition and formation of the keep-alive electrode discharge.
|
| 33. | After retrieval from the core, processing can extract the cobalt-60 for manufacture into a useful radiation source.
|
| 34. | Radiant barriers are materials that reflect radiation, and therefore reduce the flow of heat from radiation sources.
|
| 35. | Therefore, the radiation sources remain accurately targeted.
|
| 36. | The gamma gardens were arranged in a circular pattern with a retractable radiation source in the middle.
|
| 37. | Americium is commonly used in industry as both an alpha particle and low photon energy gamma radiation source.
|
| 38. | In breast brachytherapy, the radiation source is placed inside the breast, treating the cavity from the inside out.
|
| 39. | After eliminating every conceivable source of interference, they concluded that the radiation source was not of earthly origin.
|
| 40. | In contrast, brachytherapy involves the precise placement of radiation source ( s ) directly at the treatment site.
