Beta Calibration Sources
Beta Calibration Sources
- Radionuclides are deposited between two hot-sealed polyester foils (approximately 75μm thick each). Each face of the source is gold vacuum-coated for optimum measurement efficiency. They are then mounted in a steel ring.
- Radiological characteristics of the sources are measured with a calibrated gas flow proportional counter.
- Available in 0.002 uCi and 0.08 uCi
- Available in the following Radionuclides: Cl-36, Co-60, Cs-134, Cs-137, Na-22, Pm-147, Sr-89, Sr-90, Tl-204
Kits Available
EBS A and EBS B sources are also available in kit form. Radionuclides supplied are Pm-147, Cs-134, Cs-137, Sr90 + Y-90, Tl-204 and Na-22 with an activity of 0.002 μCi (80 Bq) or 0.08 μCi (3 000 Bq). Other activities of EBS sources are available on request.
