A. Any person is
exempt from this Part to the extent that such person receives, possesses, uses,
owns, or transfers source material in any chemical mixture, compound, solution,
or alloy in which the source material is by weight less than 1/20 of 1 percent
(0.05 percent) of the mixture, compound, solution, or alloy.
B. Any person is exempt from this Part to the
extent that such person receives, possesses, uses, or transfers unrefined and
unprocessed ore containing source material; provided that, except as authorized
in a specific license, such person shall not refine or process such
ore.
C. Any person is exempt from
this Part to the extent that such person receives, possesses, uses, or
transfers:
(1) Any quantities of thorium
contained in:
(a) Incandescent gas
mantles,
(b) Vacuum
tubes,
(c) Welding rods,
(d) Electric lamps for illuminating purposes
provided that each lamp does not contain more than 50 milligrams of
thorium,
(e) Germicidal lamps,
sunlamps, and lamps for outdoor or industrial lighting provided that each lamp
does not contain more than 2 grams of thorium,
(f) Rare earth metals and compounds,
mixtures, and products containing not more than 0.25 percent by weight thorium,
uranium, or any combination of these, or
(g) Personnel neutron dosimeters, provided
that each dosimeter does not contain more than 50 milligrams of
thorium;
(2) Source
material contained in the following products:
(a) Glazed ceramic tableware manufactured
before August 27, 2013, provided that the glaze contains not more than 20
percent by weight source material,
(b) Glassware containing not more than two
percent by weight source material or, for glassware manufactured before August
27, 2013, 10 percent by weight source material; but not including commercially
manufactured glass brick, pane glass, ceramic tile, or other glass or ceramic
used in construction,
(c) Glass
enamel and glass enamel frit containing not more than 10 percent by weight
source material imported or ordered for importation into the United States, or
initially distributed by manufacturers in the United States, before July 25,
1983; or
(d) Piezoelectric ceramic
containing not more than 2 percent by weight source material;
(3) Photographic film, negatives,
and prints containing uranium or thorium;
(4) Any finished product or part fabricated
of, or containing, tungsten-thorium or magnesium-thorium alloys, provided that
the thorium content of the alloy does not exceed 4 percent by weight and that
this exemption shall not be deemed to authorize the chemical, physical, or
metallurgical treatment or processing of any such product or part;
(5) Uranium contained in counterweights
installed in aircraft, rockets, projectiles, and missiles, or stored or handled
in connection with installation or removal of such counterweights, provided
that:
(a) Each counterweight has been
impressed with the following legend clearly legible through any plating or
other covering: "DEPLETED URANIUM,"
(b) Each counterweight is durably and legibly
labeled or marked with the identification of the manufacturer and the
statement: "UNAUTHORIZED ALTERATIONS PROHIBITED," and
(c) This exemption shall not be deemed to
authorize the chemical, physical, or metallurgical treatment or processing of
any such counterweights other than repair or restoration of any plating or
other covering;
(d) The
requirements specified in paragraphs C(5)(a) and (b) need not be met by
counterweights manufactured prior to Dec. 31, 1969, provided that such
counterweights were manufactured under a specific license issued by the Atomic
Energy Commission and were impressed with the legend required by C(5)(b) in
effect on June 30, 1969.
(6) Natural or depleted uranium metal used as
shielding constituting part of any shipping container provided that:
(a) The shipping container is conspicuously
and legibly impressed with the legend "CAUTION-RADIOACTIVE
SHIELDING-URANIUM," and
(b)
The uranium metal is encased in mild steel or equally fire-resistant metal of
minimum wall thickness of one-eighth inch (3.2 mm);
(7) Thorium or uranium contained in or on
finished optical lenses and mirrors, provided that each lens or mirror does not
contain more than 10 percent by weight thorium or uranium or, for lenses
manufactured before August 27, 2013, 30 percent by weight of thorium; and that
the exemption contained in this paragraph does not authorize either:
(a) The shaping, grinding or polishing of
such lens or mirror or manufacturing processes other than the assembly of such
lens or mirror into optical systems and devices without any alteration of the
lens or mirror; or
(b) The receipt,
possession, use, or transfer of uranium or thorium contained in contact lenses,
or in spectacles, or in eyepieces in binoculars or other optical
instruments.
(8) Thorium
contained in any finished aircraft engine part containing nickel-thoria alloy,
provided that
(a) The thorium is dispersed in
the nickel-thoria alloy in the form of finely divided thoria (thorium dioxide),
and
(b) The thorium content in the
nickel-thoria alloy does not exceed 4 percent by weight.
D. The exemptions in C.2.C do not
authorize the manufacture of any of the products described.
E. No person may initially transfer for sale
or distribution a product containing source material to persons exempt under
C.2.C, to initially transfer such products for sale or distribution. Persons
authorized to manufacture, process, or produce these materials or products
containing source material, and persons who import finished products or parts,
for sale or distribution must be authorized by a license for distribution only
and are exempt from the requirements of parts D and J of these rules, and C.8.A
and B.
