Front

Define the term 'effective dose' in radiation safety.

Back

Effective dose is a measure of the biological effect of radiation on human tissue, taking into account the type of radiation and the sensitivity of different tissues.

Front

What is the significance of the photoelectric effect in radiology?

Back

It is the primary interaction that contributes to patient dose during X-ray imaging.

Front

Explain the role of gonadal shielding in radiation protection.

Back

Gonadal shielding is used to protect reproductive organs from radiation exposure during imaging procedures.

Front

What is scatter radiation and why is it a concern?

Back

Scatter radiation is radiation that has been deflected from its original path, which can contribute to unnecessary exposure to patients and staff.
