To minimize static marks on radiographic film, which handling practice is recommended?

• A. Keep hands dry and move handling slowly
• B. Handle with wet hands
• C. Flip repeatedly
• D. Use gloves with powder

Answer: (A)

Static marks on radiographic film come from electrostatic discharge that occurs when film surfaces rub or slide against each other during handling. Handling the film with dry hands and moving it slowly minimizes the amount of rubbing and the rapid separation that can generate a charge and cause a discharge onto the emulsion. Dry hands also reduce the chance of moisture-related smearing or water spots that could accompany handling. In contrast, wet hands can leave water spots or smear the film, flipping the film involves more friction, and gloves with powder can deposit particles on the surface, all of which increase the likelihood of artifacts.
