the following:
(1) the quantities and kinds of sources of radiation;
(2) the location where sources of radiation are assigned;
(3) a unique identification of each source of radiation;
(4) the date of the inventory; and
(5) the name of the individual conducting the inventory.
(l) Utilization records. Utilization records shall
be maintained by each licensee or registrant in accordance with subsection
(ee)(5) of this section and shall include the following information
for each source of radiation:
(1) identification of each source of radiation to include:
(A) the make and model number and/or serial number
(or if absent, a description) of each sealed source used; or
(B) the radionuclide and activity of tracer materials
and radioactive markers used at a particular well site and the disposition
of any unused tracer materials.
(2) the identity of the logging supervisor or individual
who is responsible for receiving sources of radiation, to whom assigned;
and
(3) the locations where used and dates of use.
(m) Design and performance criteria for sealed sources
used in well logging operations.
(1) Each sealed source used in well logging applications
shall meet the following minimum criteria.
(A) The sealed source is of doubly encapsulated construction.
(B) The sealed source contains radioactive material
with a chemical/physical form as insoluble and nondispersible as practicable.
(C) The sealed source meets one of the following requirements:
(i) for a sealed source manufactured on or before July
14, 1989, the requirements from the United States of America Standards
Institute (USASI) N5.10-1968, "Classification of Sealed Radioactive
Sources," or the requirements in clause (ii) or (iii) of this subparagraph;
(ii) for a sealed source manufactured after July 14,
1989, the oil-well logging requirements from the American National
Standards Institute/Health Physics Society (ANSI/HPS) N43.6-1997,
"Sealed Radioactive Sources-Classification;" or
(iii) for a sealed source manufactured after July 14,
1989, the sealed source's prototype has been tested and found to maintain
its integrity after each of the following tests:
(I) Temperature. The test source shall be held at -40
degrees Celsius for 20 minutes, 600 degrees Celsius for one hour,
and then be subjected to a thermal shock test with a temperature drop
from 600 degrees Celsius to 20 degrees Celsius within 15 seconds.
(II) Impact. A 5 kilogram (kg) steel hammer, 2.5 centimeters
(cm) in diameter, shall be dropped from a height of 1 meter (m) onto
the test source.
(III) Vibration. The test source shall be subjected
to a vibration from 25 Hertz (Hz) to 500 Hz with a peak amplitude
of five times the acceleration of gravity for 30 minutes.
(IV) Puncture. A 1 gram (gm) hammer and pin, 0.3 cm
pin diameter, shall be dropped from a height of 1 m onto the test
source.
(V) Pressure. The test source shall be subjected to
an external pressure of 24,600 pounds per square inch absolute (1.695
x 107 pascals) without leakage.
(2) The requirements in paragraph (1) of this subsection
do not apply to sealed sources that contain radioactive material in
gaseous form.
(3) The requirements in this subsection do not apply
to energy compensation sources.
(n) Labeling.
(1) Each source, source holder, or logging tool containing
radioactive material in other than an exempt quantity, shall bear
a durable, legible, and clearly visible marking or label that has,
as a minimum, the standard radiation caution symbol with no color
requirement, and the wording DANGER (or CAUTION), RADIOACTIVE--DO
NOT HANDLE, NOTIFY CIVIL AUTHORITIES (OR NAME OF COMPANY).
(2) The labeling specified in paragraph (1) of this
subsection shall be on the smallest component, source, source holder,
or logging tool that is transported as a separate piece of equipment.
(3) Each transport container shall have permanently
attached to it a durable, legible, and clearly visible label that
has, as a minimum, the standard radiation caution symbol and the wording
DANGER (or CAUTION), RADIOACTIVE, NOTIFY CIVIL AUTHORITIES (OR NAME
OF COMPANY).
(4) Each transport container shall have attached to
it a durable, legible, and clearly visible label(s) that has, as a
minimum, the licensee's name, address, and telephone number, the radionuclide,
its activity, and assay date.
(o) Inspection and maintenance.
(1) Each licensee or registrant shall conduct, at intervals
not to exceed six months, a program of visual inspection and maintenance
of source holders (or sealed source, if there is no source holder),
logging tools, source handling tools, storage containers, transport
containers, and injection tools to assure proper labeling and physical
condition. The inspection program may be performed concurrently with
routine leak testing of sealed sources. Records of inspection and
maintenance shall be made and maintained by the licensee or registrant

(2) If any inspection conducted in accordance with
paragraph (1) of this subsection reveals damage to labeling or components
