DANGER - IMPORTANT WARNINGS
i
The system must be operated only by trained and qualified radiographers who have
read and understand this Operating Manual or by trained assistants working under their
direct supervision.
WARNING
The use of this radiographic exposure device by unqualified personnel or when safety
procedures are not fully met, could result in life-threatening dangers.
Gamma radiography systems emit high levels of highly penetrating radiation during use.
An unshielded radiation source at close range can cause injury, sickness or death to anyone
who is exposed to it even for a short period of time.
A radiation source (or an unshielded source assembly) must NOT be touched by the hands
under any circumstances.
Since gamma radiation cannot be detected by the human senses, strict operating and
emergency procedures must be followed. The proper use of calibrated and operable survey
meters must be employed to avoid potentially dangerous levels of radiation exposure.
Proper dosimetry including film badges or thermoluminescent dosimeters,
direct reading pocket dosimeters and audible alarm ratemeters must be worn during all
radiographic operations.
During use of this radiography system, never assume the position of the radiation source.
Always conduct a thorough confirmatory survey using a calibrated and operable survey
meter to verify the location of the radiation source. Be reminded that a multitude of
overexposure incidents which include injuries are directly attributed to a failure of the
radiographer to perform or supervise an adequate confirmatory survey.
It is very important and required by national regulations to prevent access by unauthorized
persons to radiographic equipment and to the area where radiography is performed.
Take advantage of the three basic radiation protection methods to minimize
radiation exposure:
TIME
Spend less time near the radiation source.
DISTANCE
Increase your distance in a direction away from the radiation source.
SHIELDING
The use of effective shielding between you and the radiation source.
Do not perform any unauthorized modifications to the radiographic exposure device or
components of the radiography system.
It is important that trained and qualified radiographers perform or supervise a daily safety
inspection of the radiography system for obvious defects prior to operation of the system.
Do not use any components that are not approved for use with the radiography system or
after-market components that may compromise the safety designed into the system.
