_Extracorporeal Blood Irradiator Source DESCRIPTION:

The Industrial Reactor Laboratories (IRL) Model 1000 source is designed to be used in extracorporeal blood irradiators.

The entire capsule is made of type 304 stainless steel.

It is annular in shape with an outside wall thickness of 0.344" (8. 74 mm) and an inside wall thickness of 0.006" (0.15 mm).

The overall length of the source is 7.0" (178 mm) with an outside diameter of 1.0" (25 mm).

The inside surface of the tubing forming the inner wall is chrome-plated.

The diameter of the chrome-plated cylindrical hole (or cavity) which runs the length of the source in 0.238" (6.05 mm).

The radioactive field generated by the source forms a cylinder surrounding the central cavity through which fluid will pass during irradiation.

Both ends of the source capsule have a raised annular ridge, which is used to hold the source in position within the irradiator.

The ridge has an inside diameter of 0.750" (19.05 mm) and an outside diameter of 0.875" (22.23 mm).

The inner height of the ridge is i

0.094" (2.33 mm) and outer height up to 0.370" (9.40 mm).

During source fabrication, a mixture of " cold" and radioactive strontium silicate beads are loaded through a fill tube into the capsule cavity.

The capsule cavity outer diameter is 0.312" (7.92 mm) and inner diameter is 0.250" (6.35 mm).

The length of the capsule cavity is 6.0" (152 mm).

In the finished source, there is an inactive length of 0.5" (12.7 mm) on either end of the strontium-filled cavity.

Up to 20 Ci (740 GBq) of strontium-90 are loaded into each capsule through the fill tube.

The sources are then evacuated and heated to a temperature not exceeding 1292 F (700 C).

After the temperature has reached equilibrium, molten aluminum of the same temperature is allowed to backfill the free spaces in the cavity, which upon solidificatio:

provides a matrix in which the strontium silicate beads are imbedded.

During construction of the sources, the maximum elapsed time between alumin 2m backfilling and removal from the heat source was 3 minutes.

At no time was the outside wall exposed to the molten aluminum.

The beads were purchased from Oak Ridge National Laboratory.

After cooling, the radioactive material was sealed within the capsule by TIG welding of a stainless steel collar to the source body.

Extracorporeal Blood Irradiator Source IABELING:

All acurces are identified by electro-etching on the source capsule.

The following is an example of the labeling on the Sources:

IRL Model B-100 20 Ci Sr-90/Y-90 8/1969.

101 PROTOTYPE TESTING:

The manufacturer subjected a prototype source to the tests 1

specified in 173.398, 49 CFR 173, in order to qualify the source as "Special Form" material.

The tests were as follows:

1.

Heat in air to a temperature of 1475'F ( 801. 7 C) and remain at that temperature for 10 minutes.

2.

Drop a distance of 30' (9.14 m) onto a hardened 0.5" (12.7 mm) steel plate.

3.

Place the source on its side on a 0.5" lead sheet covering a hardened 0.5" steel plate and strike with a flat ended 0.5" diameter steel rod 35" (889 mm) long weighing 7.75 lbs (3.5 kg), free falling a distance of 9' (2.7 m).

4.

Immerse for one week in water at a pH 5-6, at room temperature, and at a conductivity less than 2 micromhos per centimeter.

5.

Leave at a constant temperature bath of approximately 86 F (30 C) for one week.

Following the above tests, the prototype source was leak tested following the methods prescribed in section B2.8 of " USA Standard Classification of Sealed Radioactive Sources", N5.10-1968.

The prototype was leak tested by placing it in a vacuum system and evacuating for 30 to 45 minutes.

The system was then backfilled with helium at to a pressure of 300 psi (2.1 MPa) and allowed to s

remain at that pressure for 30 minutes.

The capsule was flushed with air and subsequently evacuated in a bell jar and checked for helium leakage with a Veco MS 9 spectrometer.

No helium leakage was detected.

DEVICE TYPEt Extracorporeal Blood Irradiator Source OUALITY ASSURANCE AND CONTROLt The sealed source capsule was checked initially using a hot water i

bubble test.

In this test, the source was immersed in a detergent-containing water bath at a temperature of approximately 200 F ( 93. 3*C) for at least 10 seconds and examined for gas leakage.

The source was then checked for encapsulation defects by immersing the source in a 5% NaOH solution and observing eny hydrogen evolution arisine from the contact of the solution with aluminum matrix material.

A third test was then performed by immersion in water or a detergent-containing water bath at a temperature of at least ISO'F ( 6 5. 6*C) for a minimum of one hour, in which time the total removable activity was not to exceed 0.005 pCi (185 Bq).

Sources were then stored for at least seven days and reimmersed as before.

For acceptability the total removable activity after storage was not to exceed 0.001 pCi (37 By).

All sources were subjected to the above leak testing as a means of quality control prior to shipment to customers.

SAFETY ANALYSIS

SUMMARY

As of the effective date of this document, the Model B-100 Extracorporeal Blood Irradiator Sonrce is no longer manufactured and distributed by Industrial Reactor Laboratories Inc.

The company has been out of business since 1991.

This source was approved for licensing purposes by the Atomic Energy Commission (AEC) on October 20, 1969.

There is insufficient information on file for this device to perform a safety evaluation.

Therefore, this certificate is being reissued without further review based on the original review and approval issued by AEC.
