DESCRIPTIONr
~
~
The device..is.a=right' circular-cylinder, approximately 5-3/4" (14. 61 ' cm) ' tall ' and 4 -3 /4_" '. (12. 07 cm)- ~ in diameter, with a lock t
. box:attachedi to.one# side and consists.of a depleted uranium shield enclosed ~i'n a' ' stainless steel housing.
The-housing has
~
~
itwo attachingfrings,(one. machined-into thefsurface at the bottom iof the device and_one I inch from the'" top.
The_ top and lock box i
-are heliarc'(TIG): welded tblthe device. :The. cover plate is aluminum and.is bolted to the--device using six 1/4 x 20 x 1 inch
'6~.35 mm'x 50.8'cm x 2.54 cm) bolts.
The cover' plate holds in j
(
' place a= tungsten collimator, which has a 3 /16 " ~ (4. 77. mm) ' diameter I
beam l port.
- The depleted uranium shield is a~right circular cylinder with the top taking'a hemispherical ~ dome configuration.
The' shield is

- 4. 3 " ' (10. 92 cm) - in1 diameter by; 4.455" (11.32 cm).in length.
A i
~
snap ring holds the source capsule securely into a tungsten finsert:which has been pressed into a hole centered on the outside
. edge'~of:a 2.407"1(6.11 cm)f diameter' by 1" (2.54 cm) thick depleted ~ uranium wheel.
The source wheel.is rotated by.a l
tungsten. shaft which is.0.375" (9.53' mm)' in diameter at the wheel and LO.5". (1.27 cm) -in diameter at c the locking - mechanism.
The
'wheelfis secured to the' shaft with a Woodruff: key.

A plunger-type lock, which has been

1 modified by the manufacturer-for this particular application,-is
' incorporated tof ock the source ~in either the'" exposed" or the j
l Jr
" shielded"Jpositions.
The' tungsten shaft is fitted with a lknurlediknob~which.has an arrow engraved to point to the "off"'or
'on" position.
The"off" and "on"' positions are stamped into the front'ofothe lock: box to indicate when-the source is exposed or l

shielded.
The sources can be locked in the "on" position so that while the unit is being operated for pipe inspection, the source will remain in a rigid position with no movement of the source to affect the electronic readout.
LABELING:
The device bears.the manufacturer's name plate which specifies that it contains approximately 26 pounds (11.8 kg) of depleted uranium.
The plate also specifies the isotope and the maximum activity permissible.
A second plate is attached to the device which specifies the source manufacturer, model number, serial number, activity, ar.1 date of calibration.
Two other identical labels with the conve.'tional radiatica caution symbol state
" Danger, Do Not Handle - Radioactive Material, Notify Gamma Industries, Baton Rouge, Louisiana, or Civil Authorities."
CONDITIONS OF NORMAL USE:
The device is intended primarily as a source holder to be used in a pipewall thickness gauge.
When used in this manner the operator should receive only. scatter radiation.
The radiation intensity will vary around the inspection machine depending on pipe size, pipe evaluation, material thickness, type and distance of other materials in the area.
The only way to determine the level of scatter radiation is to perform a radiation survey.
After unlocking the device, the source is exposed by manually rotating the control' knob 180 degrees clockwise.
To secure the source, the control' knob is rotated 180 degrees provided for the
" exposed" and " shielded" position.

REGISTRY OF RADIOACTIVE SEALED SOURCES AND DEVICES SAFETY EVALUATION OF DEVICE NO.: NR-300-D-886-S-DATER SEP 141993 PAGE 4-_OF 5 DEVICE TYPE:
Pipewall Thickness Gauge i r EXTERNAL RADIATION LEVELS:
With a 1,500 millicuries (55.5 GBq), Cesium-137 source in the shielded position, a survey was performed using a Gamma:
Industries Model 200 survey meter with external probe and Gamma Industries Tube Model 714, Serial No. 1010.
The meter was calibrated against a 2000 millicuries (74 GBq) Cesium-137 source.
With the source in the shielded position, the highest exposure rate at the surface of the device was 14 mrem /hr (140 pSv/hr).
The manufacturer also supplied-a radiation profile which indicated that the maximum exposure rate at'6" (15.24 cm) was 2 mrem /hr (20 pSv/hr) and the maximum exposure rate at 1 meter (39.37") was less than 1 mrem /hr (10 pSv/hr).
LIMITATIONS AND/OR OTHER CON'IDERATIONS OF USE:
S The' manufacturer. furnishes operating instructions which include
~
step-by-step instructions for using the Pipeliner Model 300A, and l
. step-by-step instructions for periodic ma'intenance of the device.
The license should include provisions for 26 pounds (11.8 kg) of depleted uranium.
This device shall be[ distributed only to persons with a specific 2,
license: issued by an Agreement State or the U.S. NRC.
It should be'noted that there are no procedures for source
~
exchange by the licensee.
The device must be returned to a source supplier for source exchange.
o l
The manufacturer has performed Type B package tests on this i
device which are being submitted to the DOT for a certificate of compliance.
However, prior to issuance of a certificate of compliance,- only Type A quantities are being shipped.
