NRC INFORMATION NOTICE 91-71: TRAINING AND SUPERVISION OF INDIVIDUALS
SUPERVISED BY AN AUTHORIZED USER
Addressees
All U.S. Nuclear Regulatory Commission (NRC) medical licensees.
Purpose
The U.S. Nuclear Regulatory Commission (NRC) is issuing this information
notice to remind licensees of the importance of providing adequate
instruction and supervision to individuals working under the supervision of
an authorized user. Supervised individuals who infrequently use radioactive
materials, such as part-time or cross-trained technologists, and
technologists whose services are used under contract of a temporary
employment service are of particular concern. It is expected that licensees
will review this information for applicability to their own procedures,
distribute this notice to those responsible for radiation safety, all
authorized users, and facility management, and consider actions, as
appropriate, to preclude situations similar to the ones described in this
notice from occurring at their facilities. However, suggestions contained
in this information notice are not NRC requirements; therefore, no specific
action or written response is required.
Description of Circumstances
Reports received by NRC of recent events that led to misadministrations or
violations indicate that some licensees are not providing individuals
working under the supervision of authorized users with adequate instruction
or supervision. In the six recent cases described below, lack of adequate
instruction and/or supervision were major contributing factors that led to:
(1) a significant diagnostic misadministration by a cross-trained
technologist; (2) the alteration of patient nuclear medicine films and
significant violations of NRC requirements by a contract temporary
technologist; (3) unauthorized transfer of radioactive material to a patient
and nearby facility; (4) a significant therapy misadministration during a
brachytherapy implant and unnecessary extremity exposure to a nurse's hands;
(5) a diagnostic misadministration of iodine-131; and (6) failure of the
licensee to have a trained operator present during patient treatment on a
High Dose Rate (HDR) Afterloader on two occasions.
Case 1: An X-ray technologist, cross-trained to perform emergency nuclear
medicine scans on an on-call basis, erroneously prepared and administered
approximately 175 millicuries of a technetium-99m labeled radiopharmaceu-
tical

instead of the prescribed dosage of 8 millicuries. This misadministration
resulted in the patient receiving excess dose for an estimated whole body
dose of 3 rad and an estimated bladder dose of 36 rad.
NRC inspection of events surrounding the misadministration revealed that the
X-ray technologist had not been adequately trained by the licensee.
Specifically, the technologist was not familiar with the correct procedures
for generator elution or the preparation of the radiopharmaceutical, nor was
the individual familiar with any of the procedures established by the
Radiation Safety Officer (RSO) or authorized users, or applicable NRC
regulations governing the facility's operations. Further review of this
case also revealed that the licensee, through the RSO, was not exercising
effective oversight of the medical use program.
Case 2: A nuclear medicine technologist, on temporary assignment from a
contracted medical personnel service, apparently presented fraudulent
nuclear medicine films for physician interpretation. An investigation
performed by the licensee revealed that the films presented for
interpretation were films from patients previously imaged at the hospital.
The licensee's conclusion was based upon two observations: 1) the names of
previously imaged patients appeared to be partially erased on the films and
covered up by the names of patients scheduled to be imaged by the contract
technologist; and 2) some of the films the licensee had reviewed had
computer generated patient names that were different from the names of the
scheduled patients. The prescribed dosages or radiopharmaceuticals actually
administered to those patients cannot be determined due to poor
recordkeeping. The licensee had not familiarized the contract technologist
with the instructions of the supervising authorized users, procedures
established by the RSO, and NRC regulations and license requirements. Also,
the licensee did not provide adequate supervision of the contract employee's
activities to ensure that proper radiopharmaceuticals were ordered,
received, administered, and disposed of. The licensee relied heavily on the
individual's credentials, including professional certifications by
technologist registries and a favorable employment history.
Case 3: A physician requested an X-ray technologist, cross-trained to
perform emergency nuclear medicine scans on an on-call basis, to perform a
patient lung scan. The technologist incorrectly prepared the technetium-99m
labeled radiopharmaceutical and infiltrated the patient dosage. As a result
of these mistakes and the patient's medical condition, the primary care
physician decided to consult with a nearby facility to see if that facility
could perform the procedure. The X-ray technologist transferred a vial of
technetium-99m to the patient's spouse for transport to the nearby hospital
since that facility did not have a sufficient amount of technetium-99m but
did have the radiopharmaceutical kit available. Upon arrival at the nearby
hospital, radiation surveys indicated that contamination was present on both
the patient, the patient's spouse, and the lead shield. A survey of the
patient's automobile did not detect radiation levels above background.
After notification by both hospitals, the NRC performed an inspection of the
licensee responsible for the unauthorized transfer of radioactive material.
The inspection revealed a number of violations associated with this
incident, including the failure to record the results of radiation and
contamination

surveys, and to prepare shipping papers. The licensee had failed to
adequately instruct the cross-trained technologist to perform nuclear
medicine procedures. In addition, if the technologist had been adequately
supervised during the training period, it might have become apparent that
the technologist was not capable of performing these procedures
independently.
Case 4: A catheter containing iridium-192 seeds encased in ribbon was
inserted through a patient's nasal cavity. According to a representative of
the nursing staff, the catheter appeared to be in place at the time of
implant. Subsequently, during the 11 p.m. to 7 a.m. shift, a second nurse
noted that the implanted catheter was located outside of the patient's nose
at approximately 12 midnight and 2 a.m. Not recognizing that the
radioactive seeds were located within the dislodged portion of the catheter,
she handled it with her bare hands and taped it to the patient's face. This
resulted in a misadministration with a significant dose contribution to the
patient's face, and unnecessary radiation exposure to the nurse's hands. At
approximately 5 a.m., another nurse removed the ribbon from the patient's
face and placed it in a lead container in the patient's room. The RSO and
radiation oncologist were notified, the catheter was reimplanted and the
treatment continued as prescribed. NRC inspection revealed that the
individual nurse assigned to care for the brachytherapy implant patient on
the midnight shift had not been adequately trained in radiation safety
precautions associated with implant patient care.
Case 5: A 37 year old female patient, 2 days post partum, was administered
5.0 millicuries iodine-131 instead of the intended dosage of 50 microcuries
iodine-131. The patient was diagnosed to have a mediastinal mass and was
referred for a thyroid scan to rule out a possible substernal goiter. In
this medical facility, this procedure normally involves a dosage of 50
microcuries iodine-131. The Physician's Assistant (PA), who is permitted by
the licensee to write orders for procedures at the request of a physician,
gave the order for the scan to the floor nurse for processing. The floor
nurse placed the order with the Nuclear Medicine department. The nuclear
medicine technologist contacted the PA to arrange a time for the scan.
During this conversation, the appropriateness of the study ordered was
questioned by the technologist based on the patient information supplied by
the PA. The PA agreed to change the order from a thyroid scan, which
required a dosage of 50 microcuries of iodine-131, to a whole body scan
requiring the administration of 5.0 millicuries of iodine-131. At no time
during this decision making process was the authorized user consulted. The
licensee had not established quality assurance procedures regarding the
ordering and administering of radiopharmaceuticals, nor had instruction to
the technologist been provided to prohibit the changing of the referring
physician's orders without authorized user approval. This is clearly a
violation of 10 CFR 35.25(a)(1) in that the licensee failed to provide the
supervised individual with adequate instruction to prohibit changing or
disregarding the prescribed procedure without the permission of an
authorized user or the referring physician.
Case 6: NRC conducted an announced inspection of a High Dose Rate (HDR)
Afterloading Brachytherapy program to review the circumstances surrounding
two reported therapy misadministrations. The license application contained
operating procedures, reviewed and approved by the radiation safety
committee, that required a trained operator to be present during any use of
the HDR unit.

During the inspection, licensee representatives informed NRC inspectors that
only their physicists are considered to be trained operators. However, on
two occasions a nurse and a dosimetrist were left to control the treatment
console during patient treatment when the trained operator was not
physically present. The licensee did not provide adequate supervision to
ensure that the unit was not operated by untrained individuals in the
absence of the trained operators.
Discussion
The regulatory requirements for supervision of individuals who use byproduct
material under the supervision of an authorized user are described in 10 CFR
Part 35, Section 35.25, "Supervision." This section provides as follows:
(a) A licensee that permits the receipt, possession, use, or transfer of
byproduct material by an individual under the supervision of an
authorized user as allowed by 35.11(b) of this part shall:
(1) Instruct the supervised individual in the principles of radiation
safety appropriate to that individual's use of byproduct material;
(2) Require the supervised individual to follow the instructions of
the supervising authorized user, follow the procedures established
by the Radiation Safety Officer, and comply with the regulations
of this chapter and the license conditions with respect to the use
of byproduct material; and
(3) Periodically review the supervised individual's use of byproduct
material and the records kept to reflect this use.
(b) A licensee that supervises an individual is responsible for the acts
and omissions of the supervised individual.
Additional requirements for the instruction of workers are described in 10
CFR 19.12, "Instructions to workers." Personnel training programs must be
described as part of each licensee's radiation safety program submitted as
supporting documentation when applying for an NRC license.
The terms "instruction" and "supervision" are not defined in 10 CFR Part 35;
however, the Statements of Consideration (SOC) for revised Part 35
(effective April 1, 1987) discusses these terms in the context of responding
to comments on the proposed rule. The following discussion is based on the
SOC. With respect to the term "instruction," NRC recognizes that
instruction may be in the form of lectures, audiovisual packages, printed
handouts, laboratory exercises, preceptorials, or apprenticeships. The
format of the instruction is not important, but it must be presented in a
manner that is appropriate for each individual's use of or exposure to
byproduct material. An opportunity for questions and answers should be an
integral part of each instruction module. The NRC recognizes that the
authorized user physician identified on the license is responsible for
providing quality medical care and the practice of medicine is regulated
differently in each state. Therefore, a prescriptive definition of
supervision that describes tasks that may be delegated, time requirements
.

for the availability of the supervising authorized user, and training
requirements may not be appropriate for all licensees. The purpose of
adequate supervision is to ensure that technologists and supervised
physicians do not use byproduct material in a manner that is contrary to the
requirements of the license or the regulations, or that is otherwise
hazardous to public health and safety. Adequate supervision must encompass
a system of checks and balances whereby the authorized user is responsible
for: (1) creating and implementing procedures and protocols for the
administration of byproduct material; (2) instructing the workers or
individuals under the supervision of the user to ensure comprehension and
compliance; (3) monitoring their performance to detect deficiencies and to
develop corrective measures, and to provide feedback to these individuals.
Licensees should review the aforementioned regulations on the instruction
and supervision of their staff to ensure that all procedures and
requirements are adequately addressed and implemented, and that sufficient
safeguards are in effect to preclude events similar to the ones described in
this notice from occurring at their own facilities.
