WARNING
The line source housing must
not
be taken apart. When the line source needs to
be replaced, the entire line source housing is returned to the supplier. See the
section
Returning the Used Line Source to the Vendor
, page 12-74 for instruc-
tions.
Due to the Gd-153 source, the CardioMD line source housings contain
significantly higher levels of radiation than normally used in clinical imaging.
Potential for radiation exposure exists. Use good radiation safety practices.
Handling of line source housings with Gd-153 sources installed shall only be
performed by Philips Nuclear Medicine employees that have had radiation
safety training classes and trained on proper handling of radioactive material.
Radiation from the line source is shut off / activated by means of a shutter. Furthermore, the line
source housing has an attenuator permitting reduction of radiation from a new line source.
Shutter Mechanism
The shutter closes the line source housing’s aperture, thereby shutting off radiation from the line
source.
