BMO - BASIC X-RAY MACHINE OPERATOR
CERTIFICATION EXAM COVERAGE
The BMO exam evaluates basic knowledge of X-ray
operation, radiation safety, and imaging principles. It
covers X-ray production, exposure factors (kVp, mA, time),
image quality, and patient positioning. It also includes
radiation protection (ALARA, shielding, time, distance),
infection control, equipment safety, and basic anatomy
recognition. Overall, it ensures safe operation of basic X-
,ray equipment while producing diagnostic images within
regulatory standards.
,An image made using 20 mAs and 100 kVp has satisfactory
radiographic density, but is lacking in radiographic
contrast. Which of the following techniques will improve
the appearance of the image?
10 mAs and 115 kVp
40 mAs and 115 kVp
10 mAs and 85 kVp
40 mAs and 85 kVp
40 mAs and 85 kVp
, The organization that sets standards and prepares
examinations necessary to cerify radiologic technologists
and limited operators is the:
American Registry of Radiologic Technologists (ARRT)
The radioation that exits the opposite side of the patient to
expose the image receptor (IR) is called:
Remnant radiation (exit radiation)
