Tube type sources |

Application
Tube type sources are used in the quality control of well-type
NaI detectors used in biomedical research and nuclear medicine.
For the quality control of multi-well detectors, matched sets
of tube sources and multi-finger sources are available. The
advantages of using a multi-finger source are:
• Saves time - 1 source for 12 measurements simultaneously
• No half life correction needed (I-129 sources)
• Sealed sources - safer to handle than liquid standards
Construction
The radioactive material is homgeneously incorporated in 1ml
of resin at the base of a plastic tube, 12mm in diameter and
75mm long. The rest of the tube is filled with inactive resin.
