DEVICE TYPE: Self-Shielded Irradiator DESCRIPTION:
The Models of Husman 520, 521, and 521a were irradiators designed j to provide an automated method to produce large quantities of sterile pupae to meet the requirements of the sterile fly rearing programs operated by the Animal and Plant Health Inspection Service, USDA. The Husman irradiators were installed in fixed locations. Their weight was 17,000 lb. (7,711 kg). Four units were used by USDA Agencies in the United States. Five units were on loan to the governments of Mexico and Guatemala for use in their programs.
The Husman irradiator consists of a rotating annular rotor between an integral central core and outer annular shell. Pupae containers are loaded by gravity-feed into one of the three equally spaced specimen chambers in the rotor, and are transported to irradiation position by revolving the rotor one- ,
i third revolution (12 0 ) . The dose absorbed is determined by the l dwell time of specimens at the position. After irradiation, the ;
i specimens are rotated to another opening and unloaded by gravitational force. The irradiation cycle is controlled by an l
index drive system which cyclically and automatically loads the
! pupae containers into the rotor, irradiates, and unloads the l specimens within a specified period of time. The unit is self-l contained and fully shielded at all times regardless of rotor position.
The entire outer skin of the Husman irradiator was fabricated of 5/8" '(1.59 cm) thick carbon steel plate. All inner plates were l of stainless stael. Additionally, a minimum of 6" (15.24 cm) of I lead shielded each source canister in all directions. l The lead shielding was poured into the cylinders in a single operation to insure complete filling and to eliminate voids.
After source loading, radiation measurements were made to verify shielding integrity.
Upon installation of the source canisters into the Husman irradiator, a lead filled plug was installed into the access port. A 5/8" (1.59 cm) carbon steel plate was then sealed with either a full penetration groove weld, or was by bolting the l I

DEVICE TYPE: Self-Shielded Irradiator l l
DESCRIPTION (Cont'd):
l plate to the outer skin, thus eliminating any possibility of l outside contact with the source. I The sealed source insert tube was fabricated of stainless steel.
The spacers were aluminum. The source tubes were sealed; no water or water vapor could enter to initiate a chemical reaction, and the electrochemical potential between the housing and the I source material should not support a reaction that would )
significantly degrade the sources. No other corrosive materials l were used near the irradiator that could have an impact on source integrity.
The radioactive sources to be used for the Husman irradiator were manufactured by Amersham as Model X-2157 and were purchased through J.L. Sheperd as their Model 6810 source.
The Husman 520 (Serial Number 001) was the original prototype of l this series. The Kusman 521 (Serial Numbers 002 through 005) I were produced with a minor change in external components used during transportation. The Husman 521a (Serial Numbers 006 through 009) were produced with a secondary heat shield added to the lower portion of the outer shell to increase its thermal ;
resistance during a fire. l Isomedix, Inc. and J.L. Sheperd and Associates had developed a modification of the shield plug in the Model 6810 source to enable field reloading of the irradiators. At this time, only Serial Number 009 had this modification.
All other irradiators were designed in accordance with the information previously sent to NRC. The modification did not affect any operating system of the irradiator, did not change any of the dimensions, and did not decrease the stated shielding characteristic of the irradiators.
As these modifications were made-to other Husman irradiators, I they were redesignated with an (R) following the model number to l indicate that they had been modified for reloading in the field. i l

DEVICE TYPE: Self-Shielded Irradiator DESCRIPTION (Cont'd):
The modification involved replacing the existing shield plug with the one shown in J.L. Sheperd's drawing No. A-0609-2-4124-1.
Prior to the insertion of the replacement sources, the shield plug was inserted in the end of the irradiator. A tungsten shielded source rod attached to the end of the ro6 containing the radioactive sources and the resulting assembly was inserted into the source chamber using a transfer cask. The tungsten plug was placed in position and steel plates were welded to the outer case of the irradiator to assure the integrity and shielding of the sources.
The original shield plug had been lead filled. The modified shield plug was also lead filled with the shielded source rod and secondary plug manufactured out of tungsten. This configuration increased the overall shielding capacity of the shield plug.
LABELING:
The Husman irradiator is labeled in accordance with 10 CFR 20.1901. The label displays the-radiation symbol, date, isotope, activity, model number, serial number, name and address of the manufacturer, and the words " CAUTION-RADIOACTIVE MATERIAL."

DEVIC 2 TYPE: Self-Shielded Irradiator CONDITIONS OF NORMAL USE (Cont'd):
The expected useful life of these irradiators was 50 years.
PROTOTYPE TESTING:
A detailed thermal analysis had been performed where the Husman irradiator had been exposed to direct sunlight and L30*F (54.44"C) still air. The steady-state analysis conservatively had assumed a 24-hour day at maximum solar heat load. The maximum steady-state temperature had been found to be 223.6*F (106.44 C). These temperatures would have no detrimental effects on the Husman irradiator.
The materials of construction used in the Husman irradiator were able to resist brittle fracture failure at temperatures as low as
-40 F (-40 C).
The entire cask structure, with the exception of the outer shell, was fabricated of an austenitic stainless steel. Austenitic stainless steel did not experience a ductile to brittle transition in the temperature range of interest (i.e., as low as
-40 F [-40*C]).
Due to the lack of sealing devices on the Husman irradiator, a differential pressure of 0.5 atmosphere (50.66 kPa) would have no effect on the Husman irradiator.
The prototype Husman irradiator had been subjected to an extensive safety analysis in order to meet the Type B package requirements for transportation in accordance with 10 CFR 71. A safety analysis report had been submitted as part of the certification process and had been found acceptable under Certificate of Compliance No. 9182.

DEVICE TYPE: Self-Shielded Irradiator l
EXTERNAL RADIATION LEVELS:
The radiation levels around the outer shell averaged less than 2 mR/hr (20 Sv/hr) at the surface of the irradiator and less than 1 mR/hr (10 Sv/hr) at 1m (3.28'), when the source activity was at a maximum. The maximum radiation level found on the end of the unit, next to the source tube shield plate had been measured at 4 mR/hr (40 Sv/hr). These radiation levels had been measured at 45 increments at each end and in the middle of an irradiator, both surface and 3 readings had been obtained.
Radiation levels did not change during operation since the sources were fixed in position.
OUALITY ASSURANCE AND CONTROL:
At the time of construction, the Husman Irradiators had been manufactured under Quality Assurance Program Approval No. 0009.
As constructed, the Husman irradiators had met the construction and performance specifications for a Type B package. The manufacturer's Quality Control program and package certification for transportation expired on September 4, 1991.
All source capsule bodies and modifications had been completed under J.L. Sheperd and Associates Quality Assurance Program Approval No. 0122, Quality Control Manual QA-RM-001-A, which covered engineering design through final fabrication. Quality Control of source encapsulation was also controlled by the manufacturers' quality assurance programs.

SAFETY ANALYSIS
SUMMARY
1 1
The Husman irradiators are no longer manufactured or distributed by the USDA and the USDA has no intention to have any more of these irradiators produced. Therefore, the registration !
certificate is being converted to an inactive registration l certificate. )
The USDA maintained the records of the oldest unit (Serial Number 001), located in Mission, TX. The USDA had found no serious operational problems with unit since 1986 and indicated that no incidents involving the Cesium scurces or exposure to excess radiation to workers had been found. l l
Based on review of the operating experience with the Husman irradiators and J.L. Sheperd Model 6810 source capsule with modification to Serial Nnumber 009, and based on the information I

l DESCRIPTION:
The Models of Husman 520,'521, and 521a were irradiators designed to provide an automated method to produce large quantities of sterile pupae to meet'the requirements of the sterile fly rearing programs operated by the Animal and Plant. Health Inspection Service, USDA. The Husman irradiators were installed in fixed locations. Their weight was 17,000 lb. (7,711 kg). Four units were used by USDA Agencies in the United States. Five units were on loan to the governments of Mexico and Guatemala for use in their programs.
The Husman irradiator consists of a rotating annular rotor between an integral central core and outer annular shell. Pupae containers are loaded by gravity-feed into one of the three equally spaced specimen chambers in the rotor, and are transported to irradiation position by revolving the rotor one-third revolution (12 0 ) . The dose absorbed is determined by the dwell time of specimens at the position. After irradiation, the specimens are rotated to another opening and unloaded by gravitational force. The irradiation cycle is controlled by an index drive system which cyclically and automatically loads the pupae containers into the rotor, irradiates, and unloads the specimens within a specified period of time. The unit is self-contained and fully shielded at all times regardless of rotor position.
The entire outer skin of the Husman irradiator was fabricated of 5/8" (1.59 cm) thick carbon steel plate. All inner plates were of stainless steel. Additionally, a minimum of 6" (15.24 cm) of 3ead shielded each source canister in all directions.

plate to the outer skin, thus eliminating any possibility of outside contact with the source.
The sealed source insert tube was fabricated of stainless steel.
The spacers were aluminum. The source tubes were sealed; no water or water vapor could enter to initiate a chemical reaction, and the electrochemical potential between the housing and the source material should not support a reaction that would significantly degrade the ,ources. Na other corrosive materials were used near the irradiator that could have an impact on source integrity.
The radioactive sources to be used for the Husman irradiator were manufactured by Amersham as Model X-2157 and were purchased through J.L. Sheperd as their Model 6810 source.
The Husman 520 (Serial Number 001) was the original prototype of this series. The Husman 521 (Serial Numbers 002 through 005) ,
were produced with a minor change in external components used j during transportation. The Husman 521a (Serial Numbers 006 l through 009) were produced with a secondary heat shield added to the lower portion of the outer shell to increase its thermal resistance during a fire.
Isomedix, Inc. and J.L. Sheperd and Associates had developed a modification of the shield plug in the Model 6810 source to enable field reloading of the irradiators. At this time, only Serial Number 009 had this modification.
All other irradiators were designed in accordance with the
,. information previously sent to NRC. The modification did not affect any operating system of the irradiator, did not change any of the dimensions, and did not decrease the stated shielding characteristic of the irradiators.
As these modifications wcre made to other Husman ir. radiators, they were redesignated with an (R) following the model number to indicate that they had been modified for reloading, in the field.

DESCRIPTION (Cont'd)- l l
The modification involved replacing the existing shield plug with the one shown in J.L. Sheperd's drawing No. A-0609-2-4124-1.
Prior to the insertion of the replacement sources, the shield plug was inserted in the end of the irradiator. A tungsten shielded source rod attached to the end of the rod containing the j radioactive sources and the resulting assembly was inserted into (
the source chamber using a transfer cask. The tungsten plug was I placed in position and steel plates were welded to the outer case of the irradiator to assure the integrity and shielding of the i sources.

SAFETY ANALYSIS
SUMMARY
The Husman irradiators are no longer manufactured or distributed by the USDA and the USDA has no intention to have any more of these irradiators produced. Therefore, the registration certificate is being converted to an inactive registration certificate.
The USDA maintained the records of the oldest unit (Serial Number 001), located in Mission, TX. The USDA had found no serious operational problems with unit since 1986 and indicated that no incidents involving the Cesium sources or exposure to excess radiation to workers had been found.
Based on review of the operating experience with the Husman irradiators and J.L. Sheperd Model 6810 source capsule with modification to Serial Nnumber 009, and based on the information

and test data cited below, we concluded that the Husman irradiators are acceptable for licensing purposes.
Furthermore, we concluded that the Husman irradiator would be expected to maintain it's containment integrity for normal q conditions of use and accidental conditions which might occur ;
during uses specified in this certificate.
Due to the location of the device, the only personnel likely to be in the vicinity of the Husman irradiator were persons performing maintenance on the device.

DEVICE TYPE: Self-Shielded Irradiator DESCRIPTION:
The Models of Husman 520, 521, and 521a were irradiators designed to provide an automated method to produce large quantities of sterile pupae to meet the requirements of the sterile fly rearing programs operated by the Animal and Plant Health Inspection Service, USDA. The Husman irradiators were installed in fixed locations. Their weight was 17,000 lb. (7,711 kg). Four units were used by USDA Agencies in the United States. Five units were on loan to the governments of Mexico and Guatemala for use in their programs.
The Husman irradiator consists of a rotating annular rotor between an integral central core and outer annular shell. Pupae )
containers are loaded by gravity-feed into one of the three f equally spaced specimen chambers in the rotor, and are transported to irradiation position by revolving the rotor one-third revolution (120 ). The dose absorbed is determined by the dwell time of specimens at the position. After irradiation, the specimens are rotated to another opening and unloaded by gravitational force. The irradiation cycle is controlled by an index drive system which cyclically and automatically loads the t
pupae containers into the rotor, irradiates, and unloads the specimens within a specified period of time. The unit is self-contained and fully shielded at all times regardless of rotor position.
The entire outer skin of the Husman irradiator was fabricated of 5/8" (1.59 cm) thick carbon steel plate. All inner plates were of stainless steel. Additionally, a minimum of 6" (15.24 cm) of lead shielded each source canister in all directions.
- The lead shielding was poured into the cylinders in a single 1 operation to insure complete filling and to eliminate voids.
After source loading, radiation measurements were made to verify shielding integrity.
Upon installation of the source canisters into the Husman irradiator, a lead filled plug was installed into the access port. A 5/8" (1.59 cm) carbon steel plate was then sealed with either a full penetration groove weld, or was by bolting the a

DEVICE TYPE: Self-Shielded Irradiator DESCRIPTION (Cont'd)-
plate to the outer skin, thus eliminating any possibility of outside contact with.the source.
The sealed source insert tube was fabricated of stainless steel.
The spacers were aluminum. The source tubes were sealed; no water or water vapor could enter to initiate a chemical reaction, and the electrochemical potential between the housing and the source material should not support a reaction that would significantly degrade the sources. Eo other corrosive materials were used near the irradiator that could have an impact on source integrity.
The radioactive sources to be used for the Husman irradiator were manufactured by Amersham as Model X-2157 and were purchased through J.L. Sheperd as their Model 6810 source.
The Husman 520 (Serial Number 001) was the original prototype of this series. The Husman 521 (Serial Numbers 002 through 005) were produced with as minor change in external components used during transportation. The Husman 521a (Serial Numbers 006 through 009) were produced with a secondary heat shield added to the lower portion of the outer shell to increase its thermal resistance during a fire. i Isomedix, Inc. and J.L. Sheperd and Associates had developed a modification of the shield plug in the Model 6810 source to enable field reloading of the irradiators. At this time, only Serial Number 009 had this modification.
All other irradiators were designed in accordance with the information previously sent to NRC. The modification did not affect any operating system of the irradiator, did not change any of the dimensions, and did not decrease the stated shielding characteristic of the irradiators.
As these modifications were made to other Husman irradiators, they were redesignated with an (R) following the model number to indicate that'they had been modified for reloading in the field.

DESCRIPTION (Cont'd)- l The modification involved replacing the existing shield plug with the one shown in J.L. Sheperd's drawing No. A-0609-2-4124-1.
Prior to the insertion of the replacement sources, the shield plug was inserted in the end of the irradiator. A tungsten shielded source rod attached to the end of the rod containing the radioactive sources and the resulting assembly was inserted into the source chamber using a transfer cask. The tungsten plug was placed in ;osition and steel plates were welded to the outer case of the irradiator to assure the integrity and shielding of tha sources.
The original shield plug had been lead filled. The modified shield plug was also lead filled with the shielded source rod and secondary plug manufactured out of tungsten. This configuration increased the overall shielding capacity of the shield plug.
LABELING:
The Husman irradiator is labeled in accordance with 10 CFR 20.1901. The label displays the radiation symbol, date, isotope, activity, model number, serial number, name and address of the manufacturer, and the words " CAUTION-RADIOACTIVE MATERIAL."

DEVICE TYPE: Self-Shielded Irradiator CONDITIONS OF NORMAL USE (Cont'd)-
The expected useful life of these irradiators was 50 years.
PROTOTYPE TESTING:
A detailed thermal analysis had been performed where the Husman irradiator had been exposed to direct sunlight and 130 F (54.44 C) still air. The steady-state analysis conservatively had assumed a 24-hour day at maximum solar heat load. The maximum steady-state temperature had been found to be 223.6*F (106.44 C). These temperatures would have no detrimental effects on the Husman irradiator.
The materials of construction used in the Husman irradiator were able to resist brittle fracture failure at temperatures as low as
-40 F (-40 C).
The entire cask structure, with the exception of the outer shell, was fabricated of an austenitic stainless steel. Austenitic stainless steel did not ;xperience a ductile to brittle transition in the temperature range of interest (i.e., as low as 1
-40 F (-40 C]).
Due to the lack of sealing devices on the Husman irradiator, a differential pressure of 0.5 atmosphere (50.66 kPa) would have no l effect on the Husman irradiator. '
The prototype Husman irradiator had been subjected to an extensive safety analysis in order to meet the Type B package requirements for transportation in accordance with 10 CFR 71. A safety analysis report had been submitted as part of the certification process and had been found acceptable under Certificate of Compliance No. 9182.

DEVICE TYPS: Self-Shielded Irradiator EXTERNAL RADIATION LEVELS:
The radiation levels around the outer shell averaged less than 2 mR/hr (20 Sv/hr) at the surface of the irradiator and less than 1 mR/hr (10 Sv/hr) at 1m (3.28'), when the source activity was at a maximum. The maximum radiation level found on the end of the unit, next to the source tube shield plate had been measured at 4 mR/hr (40 Sv/hr). These radiation levels had been measured at 45 increments at each end and in the middle of an i irradiator, both surface and 3 readings had been obtained.
Radiation levels did not change during operation since the sources were fixed in position.
QUALITY ASSURANCE AND CONTROL:
l At the time of construction, the Husman Irradiators had been manufactured under Quality Assurance Program Approval No. 0009.
As constructed, the Husman irradiators had met the construction and performance specifications for a Type B package. The manufacturer's Quality Control program and package certification j for transportation expired on September 4, 1991. j All source capsule bodies and modifications had been completed under J.L. Sheperd and Associates Quality Assurance Program Approval No. 0122, Quality Control Manual QA-RM-001-A, which covered engineering design through final fabrication. Quality Control of source encapsulation was also controlled by the j manufacturers' quality assurance programs.

REGISTRY OF RADIOACTIVE SEALED SOURCES AND DEVICES SAFETY EVALUATION OF DEVICE NO.- NR-1060-D-801-S DATE: PAGE: 2 OF,_8 DEVICE TYPE: Self-Shielded Irradiator DESCRIPTION:
The Models of Husman 520, 521, and 521a were irradiators designed to provide an automated method to produce large quantities of sterile pupae to meet the requirements of the sterile fly rearing programs operated by the Animal and Plant Health Inspection Service, USDA. The Husman irradiators were installed in fixed locations. Their weight was 17,000 lb. (7,711 kg). Four units were used by USDA Agencies in the United States. Five units were on loan to the governments of Mexico and Guatemala for use in their programs.
The Husman irradiator consists of a rotating annular rotor between an integral central core and outer annular shell. Pupae containers are loaded by gravity-feed into one of the three equally spaced specimen chambers ir. the rotor, and are transported to irradiation position by revolving the rotor one-third revolution (120 ). The dose absorbed is determined by the dwell time of specimens at the position. After irradiation, the specimens are rotated to another opening and unloaded by gravitational force. The irradiation cycle is controlled by an index drive system which cyclically and automatically loads the pupae containers into the rotor, irradiates, and unloads the specimens within a specified period of time. The unit is self-contained and fully shielded at all times regardless of rotor position. j The entire outer skin of the Husman irradiator was fabricated of 5/8" (1.59 cm) thick carbon steel plate. All inner plates were of stainless steel. Additionally, a minimum of 6" (15.24 cm) of lead shielded each source canister in all directions.
The lead shielding was poured into the cylinders in a single operation to insure complete filling and to eliminate voids.
- After source loading, radiation measuremonts were made to verify i shielding integrity.
Upon installation of the source canisters into the Husman irradiator, a lead filled plug was instal'3d into the access port. A 5/8" (1.59 cm) carbon steel plate was then sealed with either a full penetration groove weld, or was by bolting the i

plate to the outer skin, thus eliminating any possibility of outside contact with the source.
The sealed source insert tube was fabricated of stainless steel. j The spacers were aluminum. The source tubes were sealed; no water or water vapor could enter to initiate a chemical reaction,
..nd the electrochemical potential between the housing and the source material should not support a reaction that would significantly degrade the sources. No other corrosive materials were used near the irradiator that could have an impact on source integrity.
The radioactive sources to be used for the Husman irradiator were manufactured by Amersham as Model X-2157 and were purchased through J.L. Sheperd as their Model 6810 source.
The Husman 520 (Serial Number 001) was the original prototype of 1 this series. The Husman 521 (Serial Numbers 002 through 005) l were produced with a minor change in external components used f during transportation. The Husman 521a (Serial Numbers 006 )
through 009) were produced with a secondary heat shield added to i the lower portion of the outer shell to increase its thermal resistance during a fire.
Isomedix, Inc. and J.L. Sheperd and Associates had developed a modification of the shield plug in the Model 6810 source to enable field reloading of the irradiators. At this time, only Serial Number 009 had this modification.
All other irradiators were designed in accordance with the information previously sent to NRC. The modification did not affect any operating system of the irradiator, did not change any of the dimensions, and did not decrease the stated shielding characteristic of the irradiators.
As these modifications were made to other Husman irradiators, they were redesignated with an (R) following the model number to indicate that they had been modified for reloading in the field.

The modification involved replacing the existing shield plug with the one shown in J.L. Sheperd's drawing No. A-0609-2-4124-1.
Prior to the insertion of the replacement sources, the shield plug was inserted in the end of the irradiator. A tungsten shielded source rod attached to the end of the rod containing the radioactive sources and the resulting assembly was inserted into the source chanber using a transfer cask. The tungsten plug was placed in position and steel plates were welded to the outer case I of the irradiator to assure the integrity and shielding of the sources.
The original shield plug had been lead filled. The modified shield plug was also lead filled with the shielded source rod and l secondary plug manufactured out of tungsten. This configuration increased the overall shielding capacity of the shield plug. I LABELING:
The Husman irradiator is labeled in accordance with 10 CFR 20.1901. The label displays the radiation symbol, date, isotope, activity, model number, serial number, name and address of the manufacturer, and the words " CAUTION-RADIOACTIVE MATERIAL."

See Attachments 1, 2, and 3.
CONDITIONS OF NORMAL USE:
The Husman irradiators are operated in enclosed buildings and designed for the following environment conditions:
Temperature 10 C to 50 C (5J'F to 122 F)
Pressure Atmospheric Vibration Ranges from zero to mild Corrosion Ranges from zero to low corrosive vapors Fire NEC Division 2 hazardous area possible Explosion NEC Division 2 hazardous area possible

l The expected useful life of these irradiators was 50 years.
PROTOTYPE TESTING:
A detailed thermal analysis had been performed where the Husman irradiator had been exposed to direct sunlight and 130 F (54.44 C) still' air. The steady-state analysis conservatively had assumed a 24-hour day at maximum solar heat load. The maximum steady-state temperature had been found to be 223.6 F (106.44 C). These temperatures would have no detrimental effects on the Husman irradiator.
The materials of construction used in the Husman irradiator were able to resist brittle fracture failure at temperatures as low as
-40 F (-40 C).
l The' entire cask structure, with the exception of the outer shell, l was fabricated of an austenitic stainless smeel. Austenitic stainless steel did not experience a ductile to brittle l transition in the temperature range of interest (i.e., as low as l -40 F [-40 C]).
Due to the lack of sealing devices on the Husman irradiator, a differential pressure of 0.5 atmosphere (50.66 kPa) would have no effect on the Husman irradiator.
The prototype Husman irradiator had been subjected to an extensive safety analysis in order to meet the Type B package requirements for transportation in accordance with 10 CFR 71. A safety analysis report had been submitted as part of the certification process and had been found acceptable under Certificate of Compliance No. 9182.

than 1 mR/hr (10 gSv/hr) at 1 m (3.28'), when the source activity was at a maximum. The maximum radiation level found on the end ]
of the unit, next to the source tube shield plate had been measured at 4 mR/hr (40 Sv/hr) These radiation levels had been measured at'45 increments at each end and in the middle of an ,
irradiator, both surface and 3 readings had been obtained.
nadiation levels did not change during operation since the sources were fixed in position.
OUALITY ASSURANCE AND CONTROL:
At the time of construction, the Husman Irradiators had been manufactured under Quality Assurance Program Approval No. 0009.
As constructed, the Husman irradiators had met the construction and performance specifications for a Type B package. The manufacturer's Quality Control program and package certification for transportation expired on September 4, 1991.
Alz Source ;apsule bodies and modifications had been ccmpleted under J.L. Sheperd and Associates Quality Assurance Program Approval No. 0122, Quality Control Manual QA-RM-001-A, which covered engineerlag design through final fabrication. Quality Control of source encapsulation was also controlled by the manufacturers' quality assurance programs.
LIMITATIONS AND/OR OTHER CONSIDERATIONS OF USE:
- The device should be distributed to persons specifically listed in this registration by the NRC or an Agreement State.
- Handling, Storage, Use, Transfer, and Disposal: To be ;
determined by the licensing authority.
- These devices should be leak tested at intervals not to exceed 6 months using techniques capable of detecting 0.005 microcurie (185 Bq) of removable contamination.

ensure radiation safety.
- REVIEWER NOTE: All operators of the Husman irradiators are required to take a minimum 2 day course of instruction in the operation of the irradiator and in radiation safety procedures and precautions. Operators must take and pass an examination demonstrating their understanding and knowledge of the device prior to being certified in its operation.
This is a requirement of the USDA's irradiator license.
SAFETY ANALYSIS
SUMMARY
The Husman irradiators are no longer manufactured or distributed by the USDA and the USDA has no intention to have any more of these irradiators produced. Therefore, the registration certificate is being converted to an inactive registration certificate.
The USDA maintained the records of the oldest unit (Serial Number 001), located in Mission, TX. The USDA had found no serious operational problems with unit since 1986 and indicated that no incidents involving the Cesium sources or exposure to excess radiation to workers had been found.
Based on review of the operating experience with the Husman irradiators and J.L. Sheperd Model 6810 source capsule with modification to Serial Nnumber 009, and based on the information and test data cited below, we concluded that the Husman irradiators are acceptable for licensing purposes.

SUMMARY
(Cont'd)
Furthermore, we concluded that the Husman irradiator would be expected to maintain it's containment integrity for normal conditions of use and accidental conditions which might occur during uses specified in this certificate.
Due to the location of the device, the only personnel likely to be in the vicinity of the Husman irradiator were persons performing maintenance on the device.
