f DESCRIPTION 5
i The device consists of a lead filled cylinder 11-1/4" (28.58 cm)
-high constructed from a standard section of 8" (20.32 cm)
I schedule.20 steel pipe with a welded 1/4" (6.35 mm) thick steel
{
cover plate,-top and bottom.
The steel enclosed lead cylinder.is j
then' welded to a 1/2" (1.27 cm) x 1/2 " _ (1. 27 cm) - 0.D. x 0.065"
.(1.65 mm) wall stainless steel tubes, bent into 9011 arcs welded j
together and are secured inside'the cylinder.
i The tubing is arranged such that the-two source inlet holes are 180* apart, 3-3/4 "- -(9. 52 cm) from the top?of the cylinder, and i
Ethe blind'end of the arcs are located 5/16" (7.94 mm) off the j
eentral' axis of the cylinder.
The source position is arranged in such a manner that there is always a minimum of 4"-(10.16 cm) of d
lead between the source and the exterior of the device.
l In' order to prevent loss;of'the source, an external threaded boss is welded'to the exterior of the device around the source
.i entrance orifice-.
A' standard _ pipe cap'with a welded "L"
is used j
.to. enclose'the source within.the device.
The cap "L"
has a' slot, which mates with another "L" welded on the device exterior which is alsoLslotted.
'A padlock is placed in the slot to assure that j
the source is not removed by unauthorized personnel.

LABELING:
i The~ device is. labeled with the appropriate DOT transportation label; and in addition, a label;with the' standard radiation caution symbol 1in' color, specifies the isotope, activity, date of l
calibration, source serialinumber and states " Danger, Do Not

procedures for source exchange using the C-4 source exchanger.
.i Normally only one source is shipped to the licensee, the other
" source port" is used to place the licensee's depleted source for return.
Occasionally, two sources will be shipped if the licensee has an additional device into which he can place the depleted source.
