Lead crystal does not have a similar density to C4. Lead crystal reflects the x-rays back and instead of seeing through it you get a big yellow blob on your screen. That's why film photographers use lead bags to protect unexposed film when traveling. Anything that reflects x-rays is a "shield" alarm. All shield alarms require physical inspection.
