From my experience everyone uses it (perhaps the emergency setting is more intense). But my point on low radiation is that you are not behind a lead wall. Belo

From my experience everyone uses it (perhaps the emergency setting is more intense). But my point on low radiation is that you are not behind a lead wall. Below knees, arms, head are exposed. Depending on the design the seams between sections of the protective gear will also leak. And the protective gear gets tested but only periodically not before every use. All in all everything seems to align with some probability of prolongued low radiation exposure much like nuclear power plant staff.
