Radiation Health & SafetyCâu 11 / 100
A dental assistant wears a personal dosimeter badge clipped at waist level. What does this badge actually do?
a.It blocks scatter radiation from reaching the assistant
b.It sounds an alarm when the exposure limit is reached
c.It records the assistant's accumulated occupational exposure over a monitoring period
d.It measures the output of the x-ray tubehead
Giải thích
A film or thermoluminescent dosimeter badge records the wearer's accumulated occupational dose, and the monitoring service reports readings so cumulative exposure can be tracked. The badge provides no shielding and does not alarm. Tubehead output is verified separately through equipment testing and calibration, not by a personal badge.
