Note: Normally only members of the academic or research faculties will be approved as authorized
users of radioactive material. This includes individuals holding job titles of professor, associate professor,
assistant professor, instructor, research scientist, associate research scientist, assistant research scientist,
and research professor. Requests for exception to this policy must be fully justified in writing and will be
considered on a case by case basis.

Note: Keeping this list to a minimum helps eliminate duplicate orders.
Approval is requested for the following radioactive material:
Radionuclide
Chemical
and/or physical
form
Possession limit
(mCi)
Max. amount
per experiment
(mCi)
Max. amount
per year (mCi)
Provide information for each individual who will be working with radioactive material
A complete statement of training must be attached for each individual
Complete name
Employee/student
ID number
Date of birth
Job title
Date completed
orientation
Note: Every individual working with radioactive material, including authorized users, must attend the
Radiation Safety Orientation Course within three months after starting work and at least once every two
years thereafter. New applications will not be approved until this requirement is met.
2
List each physical place where radioactive material will be used or stored under this authorization.
Building name
Room number
Room use (i.e. lab, storage only,
etc.)
Describe your proposed use of radioactive materials. Be as detailed as possible. Include a description
of any special procedures that you and your staff will follow to ensure the safe use of radioactive
material under this authorization.
Note: you will be asked to detail your general radiation safety program in section 15 of this application.
If you prefer, you may combine the two sections as an overall Standard Operating Procedures section
since you will need an SOP on file for your new hires to review prior to the first use of radioisotopes.
Do you intend to transfer radioactive material procured under this authorization to other authorized
users within Montana Tech or to individuals outside Montana Tech?
Yes No
If Yes, provide information on the anticipated recipient.
Complete this section if iodinations will be performed under this authorization or if any container of a
radioiodinated compound possessed under this authorization will contain five millicuries or greater of
the isotope.
Radionuclide(s) involved:
Chemical form:
Max. activity present in any container:
Location (building and room number) of fume hood where iodinations will be performed or
where any container holding five millicuries or more of any radioiodinated substance will be
used or stored.
If you will perform iodinations, provide a brief description of the procedure that you will follow
including an estimate of the tagging efficiency you expect to achieve:
List every individual who will be performing iodinations under this authorization or who will be
handling any container with five or more millicuries of any radioactive substance.
3
Complete this section if you will work with either 100 millicuries or more of tritium as tritiated water
and/or sodium borohydride OR 25 millicuries or more of organically bound tritium.
Chemical form:
Max. activity present in any container:
Location of fume hood where work involving tritium above the specified levels will be performed.
Describe the procedures you will follow to ensure that any spill of radioactive material is promptly
detected and that appropriate steps are taken to prevent the spread of contamination:
List each individual who will be handling any container with tritium at or above the levels listed above.
Complete this section if work will be done under this authorization involving P-32
Max activity present in stock solution:
Max. activity present in container other than stock
solution:
Provide a description of the procedure you will follow for manipulating P-32 so as to minimize exposures
from P-32 to the eyes and whole body of any individual:
Provide a description of any shielding that will be provided to minimize exposures from P-32 while in
storage, while in use, and as waste material awaiting disposal:
List each individual who will be handling 0.1 millicurie of P-32 at any one time.
If sealed or plated sources will be fabricated under this authorization, describe the procedure you will
use and what leak test method you will employ to ensure source integrity.
4
If you will use commercially available sealed sources, list each source including manufacturer, model
number, isotope, activity, calibration date and location of the sealed source.
Note: if the required information is not available at the time of application, provide a general
description that can be followed by the specifics as soon as you know them.
If you will use a gas chromatograph containing radioactive material, list each source including
manufacturer, model number, isotope, activity, calibration date and location of the sealed source.
Note: if the required information is not available at the time of application, provide a general
description that can be followed by the specifics as soon as you know them.
Outline the survey program you and your staff will follow on a day to day basis to ensure that any spill
involving radioactive material is promptly identified, that contamination is not spread beyond the
immediate area of the spill and that clean-up of the spill is successfully accomplished. Also, outline
precautions you and your staff will follow to ensure that external radiation exposures are maintained as
low as reasonably achievable. List survey instruments you will use to ensure that the program is
successfully implemented including type of instrument, manufacturer, model number, and sensitivity of
each instrument used for surveying or monitoring:
5
List any biohazards involved in the use of radioactive materials and describe the special precautions
that will be taken to avoid exposure of persons to these hazards. Describe what, if any, special handling
is required for waste generated.
List all toxic chemicals involved in the use of radioactive materials involved in the use of radioactive
materials and describe the special precautions that will be taken to avoid exposure of persons to these
hazards. Describe what, if any, special handling is required for waste generated.
