If a rescuer doubles their distance from a point source of gamma radiation, the exposure rate becomes:
Answer: One-quarter
Exposure rate follows the inverse square law, so doubling distance gives one-quarter.
In a radiological incident, patient decontamination is generally performed in which zone?
Answer: Warm zone
The warm zone is the contamination reduction corridor between hot and cold zones.
Which instrument is best suited to detect alpha contamination on a surface?
Answer: Alpha scintillation or thin-window probe held very close
Alpha particles travel only a few centimeters in air, so detectors must be held within about a centimeter.
What does an electronic personal dosimeter alarm during a response indicate?
Answer: Preset dose or dose rate threshold has been reached
EPD alarms warn when set dose or dose rate limits are exceeded so responders can withdraw.
When treating a pregnant patient with suspected radiation exposure, what is the first priority?
Answer: Stabilize the mother
Maternal stabilization is the best way to protect the fetus, and dose assessment follows.
In a radiological dispersal device (dirty bomb) event, what usually causes most immediate casualties?
Answer: Blast trauma and burns
RDD radiation doses are typically low, so conventional explosion injuries dominate.
What PPE is generally appropriate for hospital staff treating a contaminated patient?
Answer: Standard precautions: gown, double gloves, mask, shoe covers
Standard contact precautions prevent staff contamination; lead aprons do not stop most contamination hazards.
