EBS point β sources

Beta point sources (EBS) Radionuclides are deposited between two hotsealed polyester foils (approximately 75μm thick each). Each face of the source is gold vacuumcoated 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.
