Pen point marker

The pen point marker, which contains a cobal 57 source, is designed to enable clinicians using a gamma camera to trace the outline of body organs or highlight regions of particular interest.

• Technique

Radioactive solution is deposited in a thin-walled “pen” tip, creating a point source.

After drying, the tip is screwed and then sealed onto the end of an aluminum rod which shows the radionuclide symbol, identification number, activity and calibration date.

Such sources are classified as “sealed sources”, and are EU approved, with classification C22212 in accordance with AFNOR NF M61-002, ISO 2919.
