APPENDIX I
UNIVERSITY OF FLORIDA
Program for Maintaining Occupational Radiation Exposure for Non-Medical Licensed
Activities at the University of Florida, As Low As Reasonably Achievable (ALARA)
I. Management Commitment
A. The University of Florida is committed to the program described in
this document for keeping radiation exposures (individual and collective) as low as
reasonably achievable (ALARA). In accordance with this commitment, we hereby establish an
administrative organization for radiation safety and will develop the necessary written
policies, procedures, and instructions to foster the ALARA concept within our institution.
The organization includes a Radiation Control Committee (RCC) and a Radiation Control
Officer (RCO).
B. The RCO will perform a review to determine methods by which exposures
might be lowered. This review shall include reviews of operating procedures and past
exposure records, inspections and consultations with the radiation control staff. A brief
summary of the audit will be prepared covering the scope of the review and the conclusions
reached, and lessons learned, if any.
C. A representative of administration shall be an active member of the
RCC. The University of Florida will consider any modifications or changes as recommended
by the Committee including those resulting from the annual review of the radiation safety
program performed by the RCO.
D. Modifications to operating and maintenance procedures and to equipment
and facilities will be made when they will reduce exposures at reasonable costs. We will
be able to demonstrate that improvements have been sought, that modifications have been
considered, and that they have been implemented where reasonably achievable. Where
modifications have been considered but not implemented, we will be prepared to describe
the reasons for not implementing them.
E. In addition to maintaining doses to individuals as far below the limits
as reasonably achievable, the sum of the doses received by all exposed individuals will
also be maintained at the lowest practicable level.
II. Radiation Control Committee
A. Review of Proposed Users and Uses
- The RCC will review the qualifications of each potential Principal Investigator (PI) and
approved user of radioactive material and radiation producing devices with respect to the
types and quantities of materials and uses for which he/she has applied to assure that the
user will be able to take appropriate measures to maintain exposure ALARA.
- When considering a new use of radioactive material, the RCC will review the efforts of
the PI to maintain exposure ALARA. The user shall have systematic procedures to ensure
ALARA and must consider the use of special radiation safety equipment, such as rubber or
disposable gloves, fume hoods, remote handling tools, and appropriate shielding in his/her
proposed use, when appropriate.
B. Delegation of Authority
- The RCC will delegate authority to the RCO for enforcement of the ALARA policy.
- The RCC will support the RCO in those instances where it is necessary for the RCO to
assert his authority. Where the RCO has been overruled by the RCC, the RCC will record the
basis for its action.
C. Review of the ALARA Program
- In association with the RCO, the RCC will perform an annual review of all current
radiation safety procedures and the development of new procedures as appropriate to
implement the ALARA concept.
- The RCC will review all instances of deviations from the ALARA philosophy. Information
in support of the review will be supplied by the RCO.
- The RCC will evaluate the institution's overall effort for maintaining exposures ALARA.
This annual review will include the efforts of the RCO, approved users and workers as well
as those of the administration.
- The RCC will perform a quarterly review of occupational radiation exposure with
particular attention to instances in which the Investigational Levels in Table 1 of Section VI are exceeded. The principal purpose of this
review is to assess trends in occupational exposure as an index of the ALARA program
quality and to decide if action is warranted when Investigational Levels are exceeded.
III. Radiation Control Officer (RCO)
A. Annual and Quarterly Review
- The RCO will perform an annual review of the radiation control program for adherence to
ALARA concepts. Reviews of specific procedures may be conducted on a more frequent basis.
- The RCO will review, at least quarterly, the external radiation exposures of approved
users and workers to determine that their exposures are ALARA in accordance with the
provisions of Section VI of this program.
- The RCO will review, at least quarterly, the records of radiation level surveys in
unrestricted and restricted areas to determine that radiation levels were ALARA during the
previous quarter.
B. Education Responsibilities for ALARA Program
- The RCO will inform PIs, approved users, workers, and ancillary personnel of ALARA
program efforts.
- The RCO will ensure that PIs, approved users, workers and ancillary personnel who may be
exposed to radiation will be instructed in the ALARA philosophy and informed that the
administration, the RCC, and the RCO are committed to implementing the ALARA concept
.
C. Cooperative Efforts for Development of ALARA Procedures
PIs, approved users, workers and ancillary personnel will be given opportunities to
participate in formulation of the procedures that they will be required to follow.
- The RCO will be in close contact with all users and workers in order to develop ALARA
procedures for using radioactive materials and radiation producing devices.
- The RCO will establish procedures for receiving and evaluating suggestions for improving
ALARA procedures and will encourage the use of these procedures.
The RCO will investigate all known instances of deviation from good ALARA practices and
will determine the causes. The RCO may require changes in working procedures to maintain
exposures ALARA.
IV. Approved Users
A. New Procedures Involving Potential Radiation Exposures
- The PI will consult with and receive the advance approval of the RCO during the planning
stage before using radioactive material for a new procedure.
- The PI will evaluate all procedures before using radioactive material to ensure that
exposure will be kept ALARA. This may be implemented through the application of trial
runs.
B. Responsibility of Principal Investigator to Persons Under His/Her
Supervision
- The PI will explain the ALARA concept and his/her commitment to maintain exposures ALARA
to all persons under his/her supervision.
- The PI will ensure that persons under his/her supervision who are subject to
occupational radiation exposure are trained and educated in good health physics practices
and in maintaining exposures ALARA.
V. Persons Who Receive Occupational Radiation Exposure
A. The worker will be instructed in the ALARA concept and its relationship
to working procedures and work conditions.
B. The worker will also be informed of recourses that are available if
he/she feels that ALARA is not being promoted on the job.
. Establishment of Investigational Levels In Order to Monitor Individual
Occupational External Radiation Exposures
The University hereby establishes Investigational Levels for occupational external
radiation exposure which, when exceeded, will initiate review or investigation by the RCO
with subsequent review by the RCC. The Investigational Levels are listed in Table 1. These levels apply to the exposure of individual
workers. In cases where it is necessary for a worker's or a group of workers' doses to
exceed these Investigational Levels, the University retains the right to establish new
Investigational Levels on the basis that this is consistent with good ALARA practices for
that individual or group. Justification for new Investigational Levels will be documented.
The RCO will review and initial the results of personnel monitoring not less than once
in any calendar quarter. Prior specific approval to operate under the more liberal State
or Federal regulations must be obtained for any such occasion from the RCC by submitting a
written proposal through the Radiation Control Officer.
A. The following actions will be taken at the Investigational Levels as
stated in Table 1.
- Quarterly exposure of individuals to less than Investigational Level I.
Except when deemed necessary by the RCO, no further action will be taken in those cases
where an individual's exposure is less than Table 1 values for Investigational Level I.
- Personnel exposures equal to or greater than Investigational Level I, but less than
Investigational Level II.
The RCO will investigate the exposure of each individual whose quarterly exposure equals
or exceeds Investigational Level I and will report the results of the investigation at the
first RCC meeting following the quarter when the exposure was recorded. If the exposure
does not equal or exceed Investigational Level II, no further action related specifically
to the exposure is required unless deemed necessary by the RCC. The RCC will, however,
consider each such exposure in comparison with those of others performing similar tasks as
an index of ALARA program quality and will record the review in the RCC minutes.
- Personnel exposures equal to or greater than Investigational Level II, but less than
Investigational Level III.
The RCO will investigate in a timely manner the causes of the exposure of each individual
whose quarterly exposure equals or exceeds Investigational Level II and will report the
results of the investigation and corrective action taken at the first RCC meeting
following the quarter when the exposure was recorded. If the exposure does not equal or
exceed Investigational Level III, no further action related specifically to the exposure
is required unless deemed necessary by the RCC. The RCC will, however, consider each such
exposure in comparison with those of others performing similar tasks as an index of ALARA
program quality and will record the review in the RCC minutes.
- Personnel exposures equal to or greater than Investigation Level III.
The RCO will promptly investigate the cause(s) of all personnel exposures equaling or
exceeding Investigational Level III will take action as appropriate. A report of the
investigation and corrective actions taken, if any, will be presented to the RCC at the
first meeting following completion of the investigation. The details of these reports will
be recorded in the minutes. RCC minutes will be sent to the administration of this
institution for review. A report of the investigation will also be made available to the
Florida Department of Health, Office of Radiation Control. The minutes, containing details
of the investigation, will be made available to Departmental inspectors for review at the
time of the next inspection.
