Summary
The efficiency of betavoltaic batteries, which convert the decay energy of radioisotope into electricity, strongly depends on the beta-ray emission rate of the source. Accurate measurement of this emission rate is essential for quality control, ensuring stable performance and extended lifetime of the batteries. However, conventional detection methods, originally designed for gamma-ray measurement, are inadequate for beta-ray detection due to the limited penetration depth of beta particles. To overcome these limitations, we developed a novel system capable of measuring both absolute and relative beta-ray emission rates of sources with high accuracy.
