Po-210 Needle Source

The Po-210 needle source is designed for creating a point source inside a cloud chamber for demonstrating alpha radiation tracks.

The Po-210 is deposited onto the eyelet of a needle which is mounted on a test tube stopper. The stopper is placed into a test tube for protection during shipping and storage.

All Po-210 needle sources have an uncertainty of +/-20%.

Not available for calibration.
