Radiation Health & SafetyCâu 12 / 100
A child cannot keep the sensor in place during a bitewing exposure. What is the correct action?
a.The assistant holds the sensor with a gloved hand during the exposure
b.The assistant holds the tubehead steady with one hand during the exposure
c.Another staff member holds the sensor for every child that day
d.Ask the parent or guardian, wearing a lead apron, to hold the receptor
Giải thích
Dental personnel must never hold a receptor or the tubehead during an exposure, because repeated exposures deliver a cumulative occupational dose. When stabilization is unavoidable, a parent or guardian who is not routinely exposed and who wears a lead apron may hold the receptor. Rotating the task among staff members does not solve the problem, since no employee should be in the beam at all.
