Other possibilities include:

1. Prolonged sitting position putting strain on the abdomen and back,
with deleterious effects on the baby.  (I can tell you working in
front a CRTs gives male engineers very high rates of back and neck
pain -- but not because of radiation).

2. Other shared characteristics of the work force?  In my experience,
women working as data entry operators are FAR more likely to smoke
than women who work in other office jobs.  This may be a quirk of
the places I've worked -- but I wouldn't discount the possibility
that there are explanations.  A few years ago, someone found that
cancer rates in one of the Bay Area counties were extremely high.
The obvious conclusion was that air pollution from the oil refinery
was at fault.  A more careful study found that the oil refinery hired
large numbers of blue collar workers, relative to the surrounding
counties, and blue collar workers are much likely to smoke.  THIS
was the cause of the cancers -- not air pollution from the refinery.

Very effective lobbying efforts are all that this demonstrates.

I've read enough about this to believe there may be a problem associated
with high tension power lines, but those aren't CRTs.
