and
(L) serving as the primary contact with the agency.
(t) Security.
(1) A logging supervisor must be physically present
at a temporary jobsite whenever radioactive material is being handled
or is not stored and locked in a vehicle or storage place. The logging
supervisor may leave the jobsite in order to obtain assistance if
a sealed source becomes lodged in a well.
(2) During well logging, except when sealed sources
are below ground or in shipping or storage containers, the logging
supervisor or other individual designated by the logging supervisor
shall maintain direct surveillance of the operation to prevent unauthorized
entry into a restricted area, as defined in §289.201(b) of this
title, or §289.231(c) of this title, as applicable.
(u) Handling tools. The licensee shall provide and
require the use of tools that will assure remote handling of sealed
sources other than low activity calibration sources.
(v) Tracer studies.
(1) Appropriate protective clothing and equipment shall
be used by all personnel handling radioactive tracer material. Precautions
shall be taken to avoid ingestion or inhalation of radioactive material
and to avoid contamination of field stations, temporary job sites,
vehicles, associated equipment, and clothing.
(2) No licensee shall permit the injection of radioactive
material into usable quality groundwater (3,000 parts per million
(ppm) total dissolved solids or less) without prior written authorization
from the agency.
(3) The well operator shall contact the licensee when
a decision is made to reverse the radioactive tracer material out
of a well. The licensee shall be on site and present at the well when
radioactive tracer material is reversed out of a well.
(w) Particle accelerators. No licensee or registrant
shall permit above-ground testing of particle accelerators that results
in the production of radiation except in areas or facilities controlled
or shielded to meet the requirements of §289.202(f) or (n) of
this title, or §289.231(m) or (o) of this title, as applicable.
(x) Radioactive markers. The licensee may use radioactive
markers in wells only if the individual markers contain quantities
of radioactive material not exceeding the quantities specified in §289.251(l)(2)
of this title. The use of markers is subject only to the provisions
of this subsection and subsection (k) of this section.
(y) Uranium sinker bars. The licensee may use a depleted
uranium sinker bar in well logging service operations only if it is
legibly impressed with the wording "DANGER (or CAUTION), RADIOACTIVE-DEPLETED
URANIUM, NOTIFY CIVIL AUTHORITIES (OR NAME OF COMPANY) IF FOUND."
(z) Energy compensation source.
(1) The licensee may use an energy compensation source
that is contained within a logging tool or other tool components.
(2) For well logging applications with a surface casing
for protecting fresh water aquifers, use of the ECS is only subject
to the requirements of subsections (j), (k), and (l) of this section.
(3) For well logging applications without a surface
casing for protecting fresh water aquifers, use of the ECS is only
subject to the requirements of subsections (e), (j), (k), (l), (cc)(4)
and (dd) of this section.
(aa) Tritium neutron generator target source.
(1) Use of a tritium neutron generator target source,
containing quantities not exceeding 30 curies (Ci) (1,110 gigabecquerels
(GBq)) and in a well with a surface casing to protect fresh water
aquifers, is subject to the requirements of this section, except subsections
(e), (m), and (dd) of this section.
(2) Use of a tritium neutron generator target source,
containing quantities exceeding 30 Ci (1,110 GBq) or in a well without
a surface casing to protect fresh water aquifers, is subject to the
requirements of this section, except subsection (m) of this section.
(bb) Radiation surveys.
(1) Radiation surveys (and calculations for neutron
sources) shall be made and recorded for each area where radioactive
materials are stored.
(2) Radiation surveys (and calculations for neutron
sources) of the radiation levels in occupied positions and on the
exterior of each vehicle used to transport radioactive materials shall
be made and recorded. Such surveys (and calculations for neutron sources)
shall include all sources of radiation transported in the vehicle.
(3) If the sealed source assembly is removed from the
logging tool before departing the job site, a survey of the tool to
verify that the logging tool is free of contamination shall be made
and recorded.
(4) If the encapsulation of the sealed source has been
damaged by an operation or is likely to have been damaged by an operation,
the licensee shall immediately conduct a radiation survey and make
a record of that survey, including a contamination survey, during
and after the operation.
(5) Radiation surveys shall be made and recorded at
the job site and/or well head for each tracer operation except for
those utilizing hydrogen-3, carbon-14, sulfur-35, or krypton-85. These
surveys shall include measurements of radiation levels before and
after the operation.
(6) Records required in accordance with paragraphs
(1) - (5) of this subsection shall also include the dates, the identification
of individual(s) making the survey, the unique identification of survey
instrument(s) used, radiation measurements in milliroentgen per hour
(mR/hr), calculations in millirem per hour (mrem/hr) (microsievert
per hour (µSv/hr)), and an exact description of the location
of the survey. Each licensee or registrant shall make and maintain
records of these surveys in accordance with subsection (ee)(5) of
this section.

are conducted shall have copies of the records/documents specified
in subsection (ee)(5)(B) - (E) and (G) - (O) of this section that
are specific to the site available at each site for inspection by
the agency.
(3) Records/documents required in accordance with paragraph
(2) of this subsection shall be maintained in accordance with subsection
(ee)(5) of this section.
