Co-57 Pen Point Markers

RadQual Co-57 Pen Point Markers are precision-manufactured sealed source constructed from 300 series stainless steel and engineered for consistent performance and reliable activity output. The streamlined design provides a defined active point with a secure threaded shielding cap for protected storage when not in use.

The marker features a 0.25″ (6.3 mm) diameter body and measures 9.26″ (23.5 cm) in overall length without the shield. With the 0.5″ wall thickness threaded cap installed, the total length is 10.1″ (25.6 cm), providing effective shielding of the active end.

Available Activity Levels

Co-57 Pen Point Markers are available in activity levels of 100 µCi, 150 µCi, 200 µCi, 250 µCi, 300 µCi, 450 µCi, 500 µCi, and 540 µCi.
