Dose Calibrator sources are manufactured by adding 20 ml activity of epoxy composition in 30 ml volume of polyethelene vial. Each dose calibrator source has its own colored-coded epoxy.

Cobalt-57, Cobalt-60, Cesium-137, Barium-133 dose calibrator reference sources can be supplied in set or individually in accordance with customer request.
