Question

10 multiple choice 1 point the half - value layer is typically expressed in kerma gray (gy) al/eq. pb/eq. 11 multiple choice 1 point if the half - value layer of diagnostic radiographic equipment is too low, it may be corrected by increasing the primary beam filtration decreasing the primary beam filtration decreasing the kvp. increasing the mas.

Explanation:

1. The half - value layer is typically expressed in terms of lead equivalence (Pb/Eq) as it represents the thickness of lead that would reduce the intensity of radiation by half. Kerma is a measure of the kinetic energy released in matter per unit mass. Gray (Gy) is the SI unit of absorbed dose. AI/Eq is not a standard way to express half - value layer.
2. If the half - value layer of diagnostic radiographic equipment is too low, it means the beam is too "soft" (has too many low - energy photons). Increasing the primary beam filtration will remove more of these low - energy photons, thus increasing the half - value layer. Decreasing primary beam filtration will make the beam softer. Decreasing kVp will reduce the overall energy of the beam but not directly correct a low half - value layer in the right way. Increasing mAs only affects the quantity of radiation, not the quality related to the half - value layer.

Answer:

1. Pb/Eq
2. increasing the primary beam filtration
