4.3 Storage and Handling
You are responsible for familiarizing yourself with all national and local radiation
safety guidelines and procedures prior to storing or handling radioactive
materials. See the Radiation Safety Manual for specific details.
Source Holder
If you must store or package the source holder, follow these steps:
1.
Ensure the shutter is closed and locked.
2. Check the current local regulations (U.S. NRC, Agreement State, or other)
to determine whether this area must have access restrictions.
3. Store the source holder in a clean, dry, and secure area.
4.4 Location
At the time you ordered your equipment, VEGA sized the source holder for
optimal performance for the designated application. If the location of the
equipment has changed or is different from the original order, notify VEGA before
installing the equipment.
Internal Obstructions
If an internal obstruction such as an agitator, baffle, or manway is directly in the
path of the radiation beam, that obstruction can shield the radiation from the
detector. Such an obstruction can diminish performance of the equipment.
Locate the source holder where process material cannot coat it.
Appropriate location ensures the continuing proper operation of the
source shutter, if applicable. Many regulatory agencies, such as the
U.S. Nuclear Regulatory Commission (NRC), require periodic
testing of the shutter. See the Radiation Safety Manual for details
about current regulations.
If your instrument has a central agitator shaft, the source holder and
the detector can mount to the vessel on a chord other than the
diameter. Mounting the source holder and the detector in this
manner allows the beam of radiation to avoid the agitator shaft.
