What happens to beam intensity when one HVL is removed?

Explanation:
An HVL, or half-value layer, is the thickness of material that reduces the beam’s intensity by one half. So each HVL represents a 50% attenuation step. If you remove one HVL, you eliminate one of those attenuation steps, meaning the beam loses less energy and its intensity becomes twice what it would be with that HVL in place. In other words, removing one HVL doubles the beam intensity relative to the level after that HVL would have reduced it. The other options would reflect adding an HVL (halving) or removing more HVLs (e.g., removing two would quadruple the intensity), which isn’t the case here.
