Co-57 Rulers & Flexible Line Sources

Aids in indicating anatomical location for SPECT Imaging and in indicating organ size or region of interest by counting the number of visible “hot and cold” segments. Custom sources can be made containing a maximum activity of 1.2 millicuries (44.4 MBq).

Co-57 Flexible Ruler (BM83-20)

• Sources contain 460 microcuries of Co-57 (20 microcuries per segment).
• Each source contains 23 “hot” 1 cm segments and 24 “cold” 1 cm stainless steel segments. Total length is 18.5”(47 cm).

Co-57 Rigid Ruler (BM83-30)

• Sources contain 160 microcuries of Co-57 (20 microcuries per segment).
• Each source contains 8 “hot” 1 cm segments and 9 “cold” 1 cm segments, total length is 6.7 inches (17 cm).

Flexible Line Source (BM83-10)

• Extremely flexible and easily shaped into configurations necessary for outlining areas of interest.
• Sources contain 150 µCi of Co-57 evenly distributed throughout the epoxy over the 19.7” (50 cm) active length. (<5 µCi/in).
• The activity is uniformly dispersed in an epoxy matrix and encapsulated in a thin “poly” tube with an 0.032” (0.8mm) inside diameter and a 0.094” (2.4mm) outside diameter.
