Part 6/10:
The challenge remained: how to measure the effectiveness of the implosion amidst the rapid destruction of experiments. To tackle this, scientists developed innovative testing methods utilizing high-speed X-rays. But these methods only provided limited insight. Robert Serber introduced the concept of embedding radioactive materials within the bomb core to gather continuous data through emitted gamma rays, creating a more comprehensive overview of core compression during experiments—which became known as the “Rala experiments.”
