Radiation Health & SafetyCâu 22 / 100
A dental assistant informs the dentist that she is pregnant. Which approach reflects accepted radiation-protection practice?
a.She must immediately stop all work in the office until after delivery
b.She may continue but must double her distance to 12 feet for every exposure
c.She may continue taking radiographs while following standard protection practices, with monitoring of her occupational dose
d.She should wear two dosimeter badges on the same collar to double the reading
Giải thích
A pregnant worker may continue normal radiographic duties as long as standard protection practices are followed and her occupational dose is monitored to stay within the much stricter limit recommended for the declared pregnancy. Removing her from all work is unnecessary, and there is no rule requiring 12 feet of distance. Wearing two badges in the same location does not provide any additional information about fetal dose.
