In following the cardinal rules of radiation protection in reducing exposure to the patient, radiographers should: Reduce the amount of the x-ray “beam on” time Utilize as much distance as warranted between the x-ray tube and the patient for the examination Place a shield between the radiographer and the source of radiation

What type of interaction is demonstrated in the following diagram? Photoelectric absorption(1).jpg

Choose the two (2) responses that accurately describe radiation protection:

What effect does atomic number have on photoelectric absorption?

What energy will the scatter x-ray photon in the following diagram possess? Compton scatter.png

If the gonads (WT=0.20) receive an absorbed dose of 1.0 Gy from alpha particles, what is the effective dose?

_____ measures the amount of radiation that is absorbed by the body per unit mass and takes into account the associated radiation weighting factor and tissue weighting factor.
