TYPES Of AUTHORIZATIONS
The two types of Authorizations to use radioactive material and
radiation sources at Duke University and the Medical Center are:
-
Authorization for use in scientific research or other applications that
do not involve human subjects; and
-
Authorization for clinical or research use in humans.
In addition, shipboard use associated with the Duke University Marine Laboratory must be covered under either the Duke University license or a
license issued by the United States Nuclear Regulatory Commission, an
Agreement State, or other recognized licensing agency.
-
STATUS OF AUTHORIZATIONS
The "status" of each Authorization (and Authorized User) falls into
one of following three categories:
-
Active: The user is authorized by the Committees to use, purchase
and possess radioactive material including equipment containing
sealed sources, irradiators, or radiation producing machines. This
person purchases or performs experiments with radioactive
material or radiation sources at least once in a year. A person must
remain classified as "active" if they possess any amount of usable
unencapsulated radioactive material or if they are using equipment
containing sealed sources, irradiators, or radiation producing
machines.
-
Inactive: The user is authorized to use, purchase and possess
radioactive material including equipment containing sealed
sources, irradiators, or radiation producing machines. An inactive
user has chosen not to perform experiments utilizing
unencapsulated radioisotope or use radiation equipment for an
extended period of time exceeding one year. A user who wishes to
change to inactive status must notify the Radiation Safety Officer in
writing of this decision. An inactive user shall have no usable
unencapsulated radioactive material (including radioactive waste)
in their possession. Inactive users who have equipment containing
sealed sources, irradiators, or radiation producing machines must
not use them and must declare this information to the Radiation
Safety Officer, in writing, at the same time as they request
"inactive" status. If an inactive user desires to reinstate their
"active" status, they must notify the Radiation Safety Officer in
writing and fulfill "Active" status training requirements.
-
Terminated: The Authorized User is no longer employed by Duke
University; is deceased; or has terminated, by their own choice or
by the direction of the Committees, their Authorization to use,
order or possess radioactive material including equipment
containing sealed sources, irradiators, or radiation producing
machines. This person has no radioactive material, equipment
containing radioactive material, or radiation producing equipment.
A "terminated status" Authorized User shall have a completed
(either prior to termination or in absentia) a "close-out" procedure,
in which the inventory of radioactive material under the
Authorization has been disposed or transferred, radioactive waste
has been removed, and rooms and facilities have been surveyed and
determined to be free of radioactive contamination. Documentation
of the "close-out" will be maintained by the Radiation Safety
Division.
-
NON-HUMAN RESEARCH USE OF RADIOACTIVE MATERIAL
-
QUALIFICATIONS
An applicant for non-human radioisotope use shall be a full-time member of
the faculty and have both training and experience commensurate with the
types and quantities of radioactive material for which application is being
made.
-
DEVELOPMENT OF WRITTEN STANDARD OPERATING
PROCEDURES
Recognizing that the types of clinical and laboratory operations encompassed
by the programs at Duke vary greatly, the Committees require that each
Authorized User develop a set of written procedures that are specific to his/her
laboratory. Laboratory-specific Standard Operating Procedures give the
individual Authorized Users autonomy in determining the day-to-day conduct
of radiation protection procedures in their laboratories, based on the nature of
their use of radioactive material and/or radiation-producing devices.
Each Authorized User's written procedures should contain the following
information, based upon the general requirements of the Duke Radiation
Safety Program:
-
The types of radioactive material and/or radiation-producing
devices present in the laboratory.
-
General safety issues that address the proper handling of
radioactive material, use of fume hoods, wearing of personal
protective equipment, etc.
-
Laboratory-specific procedures for ordering, receiving, storing
and disposing of radioactive material.
-
Laboratory-specific procedures for conducting surveys for
detection of contamination (wipe test locations, frequencies, etc.).
-
Description of laboratory-specific record-keeping procedures.
As an aid to formulating these laboratory-specific written procedures, the
Radiation Safety Division will supply any current or prospective Authorized
User with a template electronic document that is based on the radionuclides
included in the User's authorization. The User may modify this template as
required.
-
AMENDING THE AUTHORIZATION
If the Authorized User wishes to alter the conditions of the authorization (such
as by adding or deleting permitted radionuclides or devices, changing
locations of use or changing possession limits), he/she may contact the
Radiation Safety Officer directly to obtain approval to amend the
authorization. All such amendments are subject to review and approval by the
appropriate Committee.
-
PRECEPTORS
The following requirements shall apply to an individual acting as a preceptor
for the radioisotope program when the applicant does not meet the
requirements stipulated above:
-
The preceptor shall be an Authorized User.
-
The preceptor shall have such professional relationships with
the applicant as would permit real knowledge of the day-to-day
course of the use of radioisotopes. The preceptor shall have a
relationship with the applicant which would give him/her veto power over the
applicant's use of radioisotopes. Having this power, the preceptor
must be willing to accept accountability for proper radioactive
material usage.
-
AUTHORIZATION FOR MEDICAL USE OF RADIOACTIVE MATERIAL IN HUMANS
The administration of radioactive material to patients or research subjects is regulated
by the Food and Drug Administration (FDA), the State of North Carolina and the
Medical Center Radiation Control and Radioactive Drug Research Committee.
Requests for the human use of radionuclides must be sufficiently detailed to enable a
determination of compliance with current regulations and procedures.
In order to participate in the human use of radioactive material at Duke University
Medical Center, the applicant must provide evidence of possession of a medical
license issued by the North Carolina Medical Board and current registration by the
Board and possess credentials that reflect those set forth in Title 10, Part 35 of the
Code of Federal Regulations (10 CFR 35). These requirements generally involve (1) training in
basic radioisotope handling techniques, (2) supervised clinical training in an
institutional nuclear medicine or radiation oncology program, and (3) relevant
experience. The clinical training should cover all appropriate types of diagnostic
procedures. The specific recommended training requirements are outlined in
Appendix A: Training Requirements for Human Use of Radioactive Material.
Each human use shall be determined to fall into one of the following categories.
-
Well-established Medical Use: those radioactive drugs which through
previous use, (primarily in Nuclear Medicine) have proven to be safe and
effective in diagnosis and/or therapy.
-
Non-Routine Medical Use: the proposed human use of any radioactive
drug which is not identified as a well-established use.
-
Basic Human Research: the use of radioactive drugs to obtain basic
research information; but not intended for immediate therapeutic,
diagnostic, or similar purpose.
The specific requirements for authorization for each type of human use are
summarized below.
-
WELL-ESTABLISHED MEDICAL USE
For well-established medical uses, the applicant must provide evidence of
medical licensing in the State of North Carolina and credentials as described
above. The applicant's Department Chair shall directly contact the Radiation
Safety Officer with the request for authorization and supply the appropriate
documentation. The Radiation Safety Officer will review the documentation and consult the Medical Center
Committee for final approval.
-
NON-ROUTINE MEDICAL USE AND THE INSTITUTIONAL
REVIEW BOARD
Non-routine medical use is the use of radioactive material in humans, which is
neither a recognized, well-established medical use, nor meets the definition
for Basic Human Research. Non-routine medical uses of radioactive material
may be classified into one of two phases of development:
-
Clinical research which applies to a new use in humans. In this case, there
is limited experience with the new use or procedure, and limited
published precedent regarding it. The basis for proceeding with the
new use in humans is derived from the knowledge obtained from
animal studies. This phase of development includes the initial
introduction into humans and initial trials on a limited number of
patients. Investigators shall contact the Radiation Safety Officer
for evaluation and submission of proposals to the Duke University Medical
Center Radioactive Drug Research Committee (RDRC). The investigator must also
submit an appropriate protocol to the Duke University Institutional Review
Board (IRB). The Institutional Review Board approves basic and clinical
human research protocols involving investigational drugs and ionizing
radiation. The investigator shall fulfill all the relevant requirements of the
IRB with regards to submission and approval of the clinical protocol. General information to be supplied is outlined in Appendix B: Information to be Supplied For New Medical Use of
Ionizing Radiation. The requirements for radiation dose limits to research subjects, and other requirements of the RDRC, are described in the Federal Regulations under 21 CFR 361.1.
-
Clinical evaluation which applies to the planned testing of a
new diagnostic or therapeutic procedure in a clinical trial. The
procedure and results of clinical research will ordinarily be
reported in the literature or at meetings. If adequate information
has not been published, the applicant shall obtain sufficient
information from the investigators who developed the test to be
thoroughly familiar with the details.
The investigator must fulfill all appropriate FDA requirements for an
Investigational New Drug (IND). These requirements are described in the
Federal regulations under 21 CFR 312; additional information to be supplied is
outlined in Appendix C: Information To Be Submitted For Basic Human Research Use Of Ionizing Radiation Investigators shall contact the Radiation Safety Officer
for evaluation and submission of proposals to the Duke University Medical
Center Radioactive Drug Research Committee. The investigator must also
submit an appropriate protocol to the Duke University IRB.
-
BASIC HUMAN RESEARCH AND THE INSTITUTIONAL
REVIEW BOARD
Basic human research includes projects intended to obtain basic research
information regarding the metabolism (including kinetics, distribution and
localization) of a radioactively labeled drug or regarding human physiology,
pathophysiology or biochemistry; but not intended for immediate therapeutic,
diagnostic or similar benefit. For these studies:
-
the amount of active pharmaceutical ingredient or combination
of pharmaceutical ingredients to be administered shall be known
not to cause any clinically detectable pharmacological effect in
human beings, and
-
the radiation dose shall be the smallest practical to perform the
study. Under no circumstances shall the whole body effective dose
equivalent exceed a yearly cumulative value of 5 rem, or a single-exposure value of 3 rem. The total critical organ dose shall not
exceed 15 rem annually. For research subjects who have not
reached 18 years of age, the maximum permissible whole body and
critical organ exposure limitations are 10 percent of the foregoing.
A female research subject of childbearing potential shall state in
writing that she is not pregnant, or shall be given a pregnancy test
before participating in any study.
Investigators shall contact the Radiation Safety Officer for evaluation and
submission of proposals to the Duke University Medical Center Radioactive
Drug Research Committee. In addition, the investigator shall meet all the
relevant requirements of the IRB.
-
INFORMED CONSENT FOR PROCEDURES INVOLVING
IONIZING RADIATION IN CLINICAL INVESTIGATIONS
The Medical Center Radiation Control and Radioactive Drug Research
Committee has adopted the following requirements relative to expressing
radiation dosage to patients or research subjects who are participating in
clinical or basic human research.
-
The investigator shall calculate the anticipated radiation dosage
as effective dose equivalent and the dose to the critical organ
(where appropriate). Calculation should include the dose from the
initial administration and, if applicable, quarterly and yearly
cumulative exposures due to subsequent procedures.
-
The calculated dose should be expressed both as an absolute quantity (mrem) and as a
fraction or multiple of the natural background radiation, or a fraction or multiple of the
applicable FDA limits for investigational radioactive drugs or the United States Nuclear Regulatory Commission (NRC) occupational dose
limits, whichever is most appropriate to the circumstances of the study population and the
study characteristics. The expression of dosage is not restricted to the preceding
suggested formats. However, any expression of radiation dose must assist the subject in
making an informed value judgment as to the magnitude of the component of risk
attributable to ionizing radiation. Investigators may contact the Radiation Safety Division
for assistance in supplying the appropriate dose information and for templates of the
appropriate wording for subject consent forms for a variety of diagnostic procedures.
