Co-57 Flood Sources
Cobalt-57 flood sources are used to test the response uniformity of gamma cameras to ensure camera response is consistent over the total head area(s). Featherlite Cobalt-57 is uniformly dispersed in an epoxy matrix fully sealed in a high integrity ABS encapsulation. Featherlite weighs 50%-60% less than conventional models of comparative size. Lower weight means less strain to the back and greater maneuverability. Cobalt-57 Flood Sources are manufactured and 100% tested to have a coefficient variation of less than ±1.0% and integral non-uniformity of less than ± 2.5%. SPECT imaging procedures require less than ±1%coefficient of variation.
