Abstract
A two-dimensional radiation emitter has a plurality of line sources, advantageously of Gd-153. The line sources are removeably retained in the emitter, and form an array. The most active line sources are located in the center region of the array, and the activity of the sources progressively diminishes from the center of the array to the ends of the array (where the least active line sources are located). As the line sources undergo radioactive decay, they are moved towards the ends.
