• True

• False

The primary purposes of x-ray tube filtrations are to protect the patients’ skin and superficial tissue and improve the quality of the radiation beam.

• True

• False

Children require higher values of kilovoltage peak (kVp) and mAs than adults.​

• True

• False

As x-ray photons travel through the air or through an absorber (such as living tissue), the quantity and energy of the x-ray photons increase.​

• True

• False

Deterministic effects may be classified as either early or late somatic effects.​
