may be partially exposed within the Model 989 device giving rise to a very high radiation field. Treat the situation
as an EMERGENCY.
F. Safety Precautions
This system may be operated only by personnel properly authorized under a license issued by the responsible Regulatory
Authority. Operating personnel must be physically present and in direct surveillance of the controlled areas whenever the
exposure device is being used.
Considering the radiation source emits high levels of gamma radiation, it is good practice to operate the system from as
great a distance as practicable, and, if possible, from behind a radiation shield such as a heavy steel or concrete object or
around the corner from a shielding wall.
Radiography must only be performed in areas which are properly controlled and clearly posted as specified by the
applicable regulatory requirements. While assembling the system it is important to keep the exposure device locked at all
times except when operating. Locked is defined as the remote controls removed and the exposure device’s locking cover
attached with the plunger lock fully engaged and the key removed. Store the key in a secured location. When moving the
Model 989 from one location to another at a temporary job-site, it is recommended that the pneumatic actuator be removed
and the source locked in the fully secured position using the Posilok
TM
slide prior to movement.
