Final answer:
Factors such as inadequate shielding, proximity to the radiation source, and longer exposure times can increase radiation exposure for both patients and radiographers. Using lead aprons, increasing distance from the source, and reducing exposure time are essential to limit radiation doses.
Step-by-step explanation:
To increase the radiation exposure for both the patient and the radiographer, factors such as the lack of proper shielding, being too close to the radiation source, and prolonged exposure time play significant roles. Shielding, such as a lead apron, helps to absorb radiation and protect tissues not being imaged. Maintaining a greater distance from the radiation source allows radiation to spread out more, reducing exposure levels. On the other hand, limiting exposure time is crucial, as the longer the exposure, the higher the radiation dose received. Advances in technology like using faster films have reduced necessary exposure times, thus decreasing overall radiation doses in medical diagnostics.
