Diagnostic imaging professionals have a responsibility to adhere to effective radiation protection practices for which of the following reasons?1. The risk of cancer from radiologic examinations accumulates over a lifetime.2. To limit the risk of stochastic effects to a reasonable level compared with nonradiation risks and in relation to society’s needs, benefits gained, and economic factors.3. Good patient care standards dictate the use of effective radiation protection practices.4. Continually evaluating one’s radiation protection practices is necessary because radiation protection guidelines for diagnostic radiology assume a linear, nonthreshold, dose–risk relationship.

When imaging long bones, which of the following is (are) correct statement(s)?1. Choose a large enough IR so that one or both joints are included on the projection.2. Extend the collimation field so it extends 1 to 2 inches (2.5 cm to 5 cm) beyond the joints spaces as required.3. Histogram errors may occur if the system algorithm does not recognize a diagonal exposure field.4. Align the long bone parallel to the IR to prevent a histogram analysis error.
