With these safeguards, it would be virtually
impossible for any radiation to create a measurable skin dosage,
let alone a significant dosage to the uterus. If a very small amount of x-ray can be measured
passing into the leaded operator’s booth, the pregnant tech can still carry
out her radiographer’s duties if she consistently wears a full lead apron.
A lead apron should not be needed in a well leaded operator’s booth,
and this would be an advantage, because the lead aprons are hot and heavy for
the tech to wear. It must be remembered, however, that many facilities
are not fully leaded. Often,
minimal lead shielding is utilized which meets legal requirements but which does
not fully prevent the transmission of scatter radiation. The amount of legally required shielding is variable from
office to office and depends on the exposure settings of the radiographs which
are produced, the radiographic workload during the week, distance from other
personnel work areas, the types of use expected from surrounding areas, and the
construction materials of the office. This
evaluation would have to be made by a qualified radiation control specialist
because the doctor or technologist would likely have no way of knowing the
precise but varying rules for each given situation or measuring whether or not
there was any transmission of scatter radiation. Generally, x-ray facilities that were constructed within roughly the past 15 years or so are well shielded. Older facilities may not be shielded as well. Sometimes dosimetry readings have been made in the routine inspection that is conducted every three years. First, consult your inspection report to see if there is any information there. If there is still a question in any individual case, a state x-ray inspector can be contacted to come and make dosimetry readings in the lead operator’s booth. They are willing to do this to ensure that a pregnant tech is safe. State of Washington Radiation Protection Phone:
