But what about the women who become pregnant unexpectedly while working with lead? Many wouldn't want to be put in the position where their unborn child could have been harmed due to exposure above the legal limit.
Regulations don't exist for no reason, they're being updated because the current regulations will have been found to not adequately protect unborn children when women don't yet know they're pregnant.
Lots of regulations have different limits on hazardous substances where an unborn child could be affected and it's absolutely standard to treat all women as if they could possibly be pregnant.
If you went for an X-ray where the womb could be exposed they would ask you if you might be pregnant and unless pregnancy can be excluded, some radiographs won't be taken.
