Detailed explanation-1: -Take care to avoid contaminating the developing equipment. Use barriers or clean and disinfect any surfaces that become contaminated. Handling Film Without Barrier Pouches: Barrier sleeves for x-ray film packets are commercially available.
Detailed explanation-2: -In addition, the use of an appropriate fluoroscopic mode (pulsed mode, low dose mode) and collimation, as well as the use of a laser aiming line are helpful in reducing the exposure of patients, as well as the physician and medical staff, to the primary X-ray beam and scattered radiation.
Detailed explanation-3: -The contaminated film packet is the major source of cross-contamination during radiographic procedures. When the packet is removed from the patient’s mouth, it is coated with saliva (or, on occasion, with blood). For this reason the operator must always wear gloves while handling contaminated film packets.
Detailed explanation-4: -The guiding principle of radiation safety is “ALARA”. ALARA stands for “as low as reasonably achievable”. ALARA means avoiding exposure to radiation that does not have a direct benefit to you, even if the dose is small.
