EXEMPTIONS OF SOURCE MATERIAL.
(a) A person is exempt from subchs. III and X
if the person receives, possesses, uses, owns or transfers any of the following
types and forms of source material:
1. Any
chemical mixture, compound, solution or alloy in which the source material by
weight is less than 1/20 of one percent of the mixture, compound, solution or
alloy.
2. Unrefined and unprocessed
ore containing source material provided that, except as authorized in a
specific license, the person does not refine or process the ore.
3. Rare earth metals and compounds, mixtures
and products containing not more than 0.25% by weight thorium, uranium or any
combination of these.
4. Any
quantities of thorium contained in any of the following:
a. Incandescent gas mantles.
b. Vacuum tubes.
c. Welding rods.
d. Electric lamps for illuminating purposes
provided that a lamp does not contain more than 50 milligrams of
thorium.
e. Germicidal lamps,
sunlamps and lamps for outdoor or industrial lighting provided that a lamp does
not contain more than 2 grams of thorium.
f. Personnel neutron dosimeters, provided
that a dosimeter does not contain more than 50 milligrams of
thorium.
5. Source
material contained in any of the following products:
a. Glazed ceramic tableware manufactured
before August 27, 2013, provided that the glaze contains not more than 20% by
weight source material.
b.
Glassware containing not more than 2% by weight source material, or for
glassware manufactured before August 27, 2013, 10% 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 or glass enamel frit
containing not more than 10% 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.
d. Piezoelectric ceramic containing not more
than 2% by weight source material.
6. Photographic film, negatives and prints
containing uranium or thorium.
7.
Any finished product or part fabricated of tungsten-thorium or
magnesium-thorium alloys, or containing tungsten-thorium or magnesium-thorium
alloys, provided that the thorium content of the alloy does not exceed 4% by
weight and that this exemption is not deemed to authorize the chemical,
physical or metallurgical treatment or processing of any product or
part.
8. Uranium contained in
counterweights installed in aircraft, rockets, projectiles or missiles or
stored or handled in connection with installation or removal of the
counterweights, under all of the following conditions:
a. Each counterweight has been impressed with
the following legend clearly legible through any plating or other covering:
"DEPLETED URANIUM". This requirement need not be met by counterweights
manufactured prior to December 31, 1969 provided that the counterweights are
impressed with the legend "CAUTION - RADIOACTIVE MATERIAL - URANIUM".
b. Each counterweight is durably and legibly
labeled or marked with the identification of the manufacturer and the
statement, "UNAUTHORIZED ALTERATIONS PROHIBITED". This requirement need not be
met by counterweights manufactured prior to December 31, 1969 provided that the
counterweights are impressed with the legend "CAUTION - RADIOACTIVE MATERIAL -
URANIUM".
c. This exemption may not
be deemed to authorize the chemical, physical or metallurgical treatment or
processing of any of these counterweights other than repair or restoration of
any plating or other covering.
9. Natural or depleted uranium metal used as
shielding constituting part of any shipping container, provided that the
shipping container is conspicuously and legibly impressed with the legend
"CAUTION - RADIOACTIVE SHIELDING - URANIUM"; and the uranium metal is encased
in mild steel or equally fire resistant metal of minimum wall thickness of 3.2
millimeter (one-eighth inch).
10.
Thorium or uranium contained in or on finished optical lenses and mirrors,
provided that a lens or mirror does not contain more than10% by weight of
thorium or uranium or for lenses manufactured before August 27, 2013, 30% by
weight of thorium and that this exemption is not deemed to authorize either of
the following:
a. The shaping, grinding or
polishing of the lens or manufacturing processes other than the assembly of the
lens into optical systems and devices without any alteration of the
lens.
b. The receipt, possession,
use or transfer of thorium contained in contact lenses, spectacles, eyepieces
in binoculars or other optical instruments.
11. Thorium contained in any finished
aircraft engine part containing nickel-thoria alloy, provided that the thorium
is dispersed in the alloy in the form of finely divided thoria, and the thorium
content in the nickel-thoria alloy does not exceed 4% by weight.
12. Only persons authorized by a license
issued under 10 CFR
40.52, may initially transfer for sale or
distribution such products containing source material to a person exempt under
this subsection.
13. Persons
authorized by an agreement state to manufacture, process, or produce materials
or products containing source material, and persons who import finished
products or parts for sale or distribution, shall be licensed for distribution
only under 10 CFR
40.52, and are exempt from s.
