DANB Radiation Health and Safety (RHS) Practice Exam

Which factor is NOT recommended when taking radiographs for children?

1. Shorter exposure times

2. Use of adult settings

3. Utilizing smaller film sizes

4. Verifying patient cooperation

The correct answer is: Use of adult settings

Using adult settings when taking radiographs for children is not recommended because children have different anatomical and physiological characteristics compared to adults. Their smaller size and developing tissues require adjustments to ensure both safety and effectiveness during imaging. Adult settings can lead to inappropriate radiation dosage, which can be harmful to a child's developing body. In contrast, shorter exposure times are beneficial as they minimize radiation exposure while still capturing quality images. Utilizing smaller film sizes accommodates the smaller mouths and dental structures of children, making the procedure more comfortable and effective. Lastly, verifying patient cooperation is essential to ensure that the child remains still, which helps in obtaining clear, high-quality images without the need for repeated exposures. This approach aligns with radiation safety principles, particularly the ALARA (As Low As Reasonably Achievable) concept, which aims to minimize radiation exposure to patients.
