PB-210 Needle Cloud Chamber Source Contains Pb-210 Sample radioactive sources for testing the functionality of a Geiger counter.

Safe, uncalibrated solid sealed sources are fabricated by depositing a license exempt quantity of activity in the well of a 1-inch diameter (25mm) by 1/8-inch thick (3mm) plastic disk.

The count-rate of each half disc plus the blank (to maintain constant geometry) is measured and then both active half discs are combined for a measurement with high count-rate.

The counting loss may now be calculated by adding the rates from each half disc and comparing the result to the count-rate with both halves combined.

The words "Caution - Radioactive Material" appear on the label of each source.

Several types of source certificates are available for an additional fee.

Radioactivity is the conversion of one nuclear state to another.
