beta sources

• Sources for calibration of beta detectors

Designed for efficiency calibration of beta detectors and counting systems, beta point sources are characterized in terms of the emerging flux of beta particles, expressed in s^-1, within a solid angle of 4 pi sr.

• Technique

The sources are hot-sealed between two thin plastic foils and gold-coated. They are then mounted in a removable metal ring to ensure rigidity and ease of handling.
They can be used with or without the ring holder for calibration of all beta detectors, including windowless 2 pi or 4 pi counters
