Dose Calibrator Reference Standards
| Dose Calibrator Reference Sources provide a safe and convenient method of calibrating instruments for measuring the accuracy of imaging solutions most commonly utilized by medical technicians. The Dose Calibrator is manufactured by uniformly distributing the active element in 20mL of epoxy, comprising a density of approximately 1.0 g/cm3. Each standard is supplied in a 27mL polyethylene vial. Calibration is in terms of activity contained in an aqueous solution. NIST traceable within ±5% at the 99% confidence level. |

Spot Markers
|
IPL Spot Markers are used for patient orientation during the performance of a camera study. A 3.45mm diameter active area is marked with purple epoxy and centered in a 25.4 x 6.35mm clear acrylic disk. Contained activity is supplied as a nominal value ±15%.

Pen Point Markers
| The IPL Pen Point marker is used to mark a point of interest during a camera study. The Pen Point Marker contains Co-57 in a ceramic matrix at the end of a12.7 cm anodized aluminum rod. The pen-shaped rod screws into a brass cap which shields the active point. The Pen Point Marker is used in tracing the outlines of anatomical features on a patient. The trace appears almost instantly on the camera display. Contained activity is supplied as a nominal value +/-15%. |

Flexible Rulers
|
Radioactive rulers and markers are used to define anatomical locations and/or organ size during a camera study. The Flexible Ruler is a plastic tube 4.8 mm in diameter containing 47 alternating 10mm sections of Co-57 and inactive lead. The overall length of the ruler is 47cm with an active length of 45cm. Contained activity is supplied as a nominal value ± 15%.

|
Flexible Markers
|
Co-57 uniformly dispersed in an epoxy matrix is injected into a 2.4mm outer diameter flexible plastic tube having an inner diameter of 0.508mm. The overall length and the active length of the ruler is 50cm. Contained activity is supplied as a nominal value ±15%.
|
|
|
Rigid Rulers
|
The Rigid Ruler is a plastic tube 5mm in diameter containing 17 alternating 10mm sections of Co-57 and inactive lead. The overall length of the ruler is 17cm with an active length of 15cm. Contained activity is supplied as a nominal value ±15%.

Gamma Tube Standards
|
Each source consists of a polypropylene test tube containing 0.75 mL of active epoxy with the balance of the test tube filled with cold epoxy. Each set contains Ba-133, Cs-137, Co-57, Co-60, Cd-109, Mn 54, and Na-22.
Test tube sizes available: 75 x 12mm, 55 x 12mm.
A variety of other nuclides and tube sizes are available upon request. Customer-supplied tubes can be utilized upon request. Tube sources are calibrated as NIST traceable with an accuracy of ±5% at the 99% confidence level.

Well Counter (Rod) Standards
|
Each source consists of a Lucite rod measuring 127 x 12.7mm or 74.9 x 12.7mm. The activity is located in a 4.75 x 4.75mm well, positioned approximately 6.35mm from the top of the rod. Set includes Ba-133, Cs-137, Co-57, Co-60, Cd 109, Mn-54, and Na-22.
Rod sources are calibrated and NIST traceable with an accuracy of ±5% at the 99% confidence level.
