Thickness Gauge DESCRIPTION:
.The Integrated Industrial Systems, Inc. (I2S) Model RSS-06 is used for the measurement of the' thickness of various materials, customarily in the sheet metal industry.
The device consist of a C-Frame with a measuring gap that varies according to the application.
The measuring gap has a maximum dimension of 3.94" (10 cm).
The C-Frame has the following variable dimensions:
Maximum Minimum (inches)
(cm)
(inches)
(cm)
Length 101.25 257.18 18 45.72 Height 16.5 41.91 15 38.1 The C-Frame is 9" (22.86 cm) wide.
It is a welded assembly constructed of 0.375" (9.53 mm) low carbon steel.
The radioactive source is mounted in the base of the device and j
is fixed in place by a source holder which is mounted within a steel source housing.
The sealed source contains americium-241 with a maximum activity of 1 curie.
The americium-241 source contains radioactive material incorporated in a ceramic enamel which is sealed in a welded stainless steel capsule.
The source
~is distributed by Amersham Corporation and is registered with the State of Illinois as the Model AMC.19.
An alternative source is distributed by BEBIG Trade, Inc. and is registered with the State of Illinois as the Model Aml.G44.
The source housing is approximately 6" x 6" x 4" (15.24 cm x 15.24 cm x 10.16 cm) and constructed of carbon steel.

Thickness Gauge DESCRIPTION (Cont'd)-
The top of the housing has 1.7" (4.23 cm) diameter window which is covered with 0.002" (0.051 mm) thick stainless steel and includes a bronze collimating assembly.
The source is housed in a stainless steel holder which is equipped with a bronze shutter, 0.125" (3.18 mm) thick.
The shutter is controlled by a rotary solenoid which is equipped with a spring to hold the shutter in the closed position.
When power is supplied to the solenoid, the shutter rotates to the open position.
Mounted on top of the C-Frame are two lights, one red and one green.
The green light indicates the source is covered (closed) and the red that the source is exposed (open).
This may be physically verified by looking through a glass peep hole on the front of the source-housing.
Green and red strips are painted on the shutter to correspond to the indicator lights.
The device is designed so that the shutter mechanism will automatically close when there is no material in the measuring gap of the C-Frame, when power is lost, or when the receiver head is removed from the C-Frame.
LABELING:
The' device contains three labels.
The first has a yellow background, black letters, with a magenta trefoil symbol, as defined in Section 20.1901, 10 CFR Part 20.
The label also in~cludes the isotope, activity, model number, serial number, date of assay of the source, and the name and complete address of I2g,

Thickness Gauge LABELING (Cont'd):
The second. label also has a yellow background, black letters, with a magenta' trefoil symbol.
It includes a warning to not remain within 3 feet of the device, indicates that the green
. light means the. source is "OFF",
and warns not to place hands within the measuring gap.
The third label has a black background with white letters.
It contains wording which meets the requirements of 10 CFR 32.51(a) (3) (iii).
A copy of the label is shown in attachment 2.
When distributed to specific licensees, the first sentence of the paragraph on the label is removed.
All three labels contain a caution against removing the label.

See attachments 1 and 2.
CONDITIONS OF NORMAL USE:
The Model RSS-06 thickness gauge is designed to measure the thickness of. thin sheets of various types'of metals.
The device will typically _be used on rolling mills in a factory environment by metal producers..The device is not likely to be subjected to extremes of environmental or operating conditions.

Thickness Gauge PROTOTYPE TESTING:
I2S did not supply prototype test results regarding mechanical operation (e.g., no specific data on retention of the source when the device is subjected to mechanical stimuli).
In lieu of such submission, I2S relied on the ANSI-N542 classification of the source and the past use of an almost identical device which they currently distribute in the U.S.
EXTERNAL RADIATION LEVELS:
The manufacturer reports that the dose rates for Model RSS-06 transmission gauge containing a 1.0 curie, Am-241 sealed source will not exceed the following:
Maximum Radiation Level Distance Shutter Open Shutter Closed (inches)
(cm)
(mem/hr)
(Sv/hr)
(mrem /hr)
(msv/hr) 1.97 5
1.2 12 0.85 8.5 11.81 30 0.3 3
0.02 0.2 39.37 100 0.03 0.3' O.006 0.06 The dose rates were taken with no material present in the measuring gap.
I2S indicates this represents the highest radiation levels of any of the possible configurations.

. SAFETY ANALYSIS
SUMMARY
' Ias has submitted sufficient information to provide reasonable assurance that:
- The device can be safely-operated by persons not having training in radiological protection.
- Under ordinary conditions of handling, storage, and use of the device,cthe byproduct material contained in the device will'not be. released or-inadvertently removed from the source housing, and it is unlikely that any person will receive in any period of one year a dose in excess of 10 percent of'the limits specified in Section 20.1201(a),
~
- Under accident conditions associated with handling, storage, and use of the source housing, it is unlikely that any person would receive an external radiation dose or dose commitment in excess of the dose to the appropriate organ as specified in the following chart:
PART OF BODY DOSE Whole body; head and trunk; active blood-forming organs; gonads; or lens of eye 15 rem (0.15 SV):
-Hands and forearms; feet and ankles;. localized areas of skin averaged over areas no larger than 1 square. centimeter 200 rem '(2.0 Sv)
Other organs-50 rem (0,50 Sv)
