I DESCR!pTION:

i 1 The Model AMM 1001 sealed source consists of americ'ium oxide uniformly distributed j and sintered in a pure gold matrix which is further contained between a backing of i gold coated pure silver and a front covering of either gold or gold-palladium alley ano fabricated by hot forging methods. The continuousl 4

rolled so that the minimum thickness of the layers are:y welded metal layers are 1

I gold palladium alloy 0.0015 mm l l americium oxide plus cold 0.0001 mm '

gold 0.0001 'un j substrate 0.20 mm Sub-division of the rolled foil is accomplished by cutting or punching into discs of 5 mm diameter or strips of say 2 mm x 10 mm diameter. At the activity loading specified above, there is tw loose or wi'pable contamination above the wipe test limit of 0.006 microcuries.

The Model AMM 1001H mounted sealed source consists of a sized foil mounted in a "T" shaced standard holder constructed of tin plated brass. Lips of the source holder are rollac over the edge of the foil so the cut edges of the foil are net exposed.

The larger diameter of the holder is approximately 5 mm and the lengtn is soproximately 6 mm. The useful life is 20 years. ,

LABEL'NG:

Neither the foils nor mounts are labeled. This evaluation does not describe possible A/S foil sources distributed under other model designations nor sources ,

previously cistributed under "AMM"' designation.

i PROTOTYPE TESTING:

Prototype Model AMM 1001 blanked sealed sour. css and Model AMM 1001H meunted sources have been tested to conditions described by USASI standard N5.10-1968 and j respective classifications of C54545 and C44444 have been demonstrated. Results 4

of wipe tests of the tested foils were acceptable to less than 0.005 microcuries, j In additten, AMM 1001 samples have successfully passed "special form" testing i

conditions.

Model AMM 1001 foils have experienced the following additional tests:

1. Immersion in water of prototype foils fer 3 weeks at room temperature: less j l than 0.001 microcurie per foil loaded at maximum activity was found in the i 1 water.

Immersion in 0.1 N hydrochloric acid for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> at room temperature: less

< 2.

than 0.004 microcurie activity was leached out. t 4 ,

2

3. Foils were subjected to tests in moist air, dry air, sulfur dioxide fumes, i hydrochloric acid fumes, ammonia vapor, to repetitive wipe tests (5000X) and

?

welding tests: less than 0.005 microcurie wipable contamination was found.

Shrelf-life tests of foils with 50 microcuries/cm2 loading show no deleterious aging effects after 6 years.

00ALITY ASS'JRANCE AND CONTROL

, Not less tnan 10 percent of the Model AMM 100lH sources are checked by gamma l ccunting to ensure that the activity in each foil is within specified limits. Each product is visually inspected to check that the rolled over edge is satisfactory and that the alpha emitting surface is free from surface defects. Each source is wipe tested to an acceptance limit of 0.005 microcuries.

l; In addition to the above, each Model AMM 1001 foil is checked by alpha s'pectrometry to determire the adequacy of the gold cover.
