C-THRU Flood Sources

Cobolt-57 Flood Sources For Gamma Cameras, by EZIP

C-Thru Flood Source by EZIPThe EZIP C-Thru Co-57 Flood Sources (formerly IsoTrak) are designed for improved performance, safety, and handling. These Flood Sources are manufactured in the United States. The C-Thru Flood Source is a considerable advance over conventional flood source design. The joined source holder material is made of transparent, durable plastic. The source holder material is transparent and the radioactive area is clearly visible, enabling C-Thru™ sources to be easily be placed on the gamma camera head, assuring full and accurate coverage of the field-of-view, while minimizing radiation exposure to the technicians hand.

Dual head cameras can be checked simultaneously as the radiation field produced by the flood source is the same on both sides. C-Thru™ flood source have 2 handles for safe manipulation allowing hands to be clear of the active area. All C-Thru™ flood sources are supplied in a stable, easy to handle lead-lined roller case for safe transport and storage. The roller case is also a Type A approved shipping container that meets all the requirements of IAEA TS-R-1 and 49CFR.

Co-57 flood sources are used for gamma camera image quality assurance. The objective of using these flood sources for routine quality assurance checks is to ensure that the gamma camera field-of-view image is free from non-uniformities and artifacts. Our uniform Cobalt-57 (Co-57) Flood Sources provide quality control of gamma imaging cameras. NASI Co-57 Flood Sources are available in standard and custom configurations in a wide range of activity levels. Many of our circular and rectangular flood sources are in stock and ready for fast delivery. Match your camera with the appropriate C-thru Flood Source model.

C-THRU Co-57 Flood Source features:

• Flood Source is constructed of transparent, durable capsule material
• Active area of flood source visible through its transparent holder
• Flood Source is transported in durable storage case with lead shield (Type A approved)
• Coefficient of variation <1% - typically the CoV is 0.5% or less
  (Unit cell size 1 cm²)
• Integral uniformity < 2.0% - typically it is 1.0%-1.7%
• Radionuclide impurity < 0.1% (Co-58, Co-56, Co-60)
• Flood Sources are available for all common gamma cameras
• Flood source can be custom designed for most dimensions and activities

Uniformity measurement

The homogeneity of each C-Thru™ flood source is measured with a special dedicated gamma camera measuring system. 100% of the active area is measured with a unit cell size of 1 cm². The results are stated in a certificate supplied with each source.
