(1) Panoramic devices (devices in which the source is physically removed from shielded container during exposure) should be inspected for: (a) Radiographic exposure unit; (i) Abnormal surface radiation levels anywhere on camera; (ii) Condition of safety plugs; (iii) Proper operation of locking mechanism; (iv) Condition of pigtail connector; (v) Alignment of "S" tube with exit port; (vi) Condition of carrying device (for example, straps and handles); (vii) Proper labeling; (b) Source tube; (i) Rust, corrosion, dirt, or sludge buildup inside the source tube; (ii) Condition of source tube connector; (iii) Condition of source stop; (iv) Kinks or damage that could prevent proper operation; (c) Control cables and drive mechanism; (i) Proper drive mechanism for this camera, if appropriate; (ii) Changes in general operating characteristics; (iii) Condition of connector on drive cable; (iv) Drive cable flexibility, wear, and rust; (v) Excessive wear or damage to crank assembly parts; (vi) Damage to drive cable conduit that could prevent the cable from moving freely; (vii) Connection of the control cable connector with the pigtail connector for proper mating; (viii) Proper operation of source position indicator, if applicable. (2) Directional beam devices should be inspected for: (a) Abnormal surface radiation; (b) Changes in the general operating characteristics of the unit; (c) Proper operation of shutter mechanism; (d) Chafing or binding of shutter mechanism; (e) Damage to the device which might impair its operation; (f) Proper operation of locking mechanism; (g) Proper drive mechanism with this camera, if appropriate; (h) Condition of carrying device (for example, straps and handles); (i) Proper labeling.
