Final answer:
On-the-job movie marathons are not part of an effective educational program for radiographers, which typically includes clinical rotations, classroom lectures, and laboratory sessions. Work involving frequent use of radiation equipment or insufficient shielding can increase a worker's radiation exposure.
Step-by-step explanation:
Among the options listed, c) On-the-job movie marathons is not one of the planned and structured learning experiences of an effective educational program for radiographers. Effective educational programs for radiographers typically include a mixture of clinical rotations, classroom lectures, and laboratory sessions to provide comprehensive practical and theoretical knowledge in radiography. These structured experiences are essential for developing the competencies required for professional practice.
Work that is likely to cause an increase in radiation exposure to a particular worker can include tasks that involve frequent use of radiation-producing equipment, long-duration procedures, or interventions without proper shielding or distance from the radiation source. Occupations such as interventional radiology, fluoroscopy, and certain types of nuclear medicine can involve higher exposure risks.
