Radiation Safety Policies
Radiation safety use and enforcement policies are
set by the Universitys Radiation Safety
Committee, (RSC). Dr. Mark Fitch, of civil
Engineering is the chair of the RSC. Policies are
based both on the Universitys Radioactive
Materials License and Reactor License Conditions.

UMR Handbook of Radiological Operations
The UMR Handbook of Radiological Operations is
the official guide in all matters relating to
radiation protection and control of radioactive
materials at the University of
Missouri-Rolla(UMR). It has been prepared by the
Radiation Safety Office with input from the UMR
Radiation Safety Committee (RSC) which serves as
the advisory body to the Chancellor, faculty, and
staff of the UMR campus for matters related to
radiation protection and control.
9
Continue
The complete Handbook is available at
http//www.umr.edu/ehs/radiological/umrhandbook
.html The UMR Radioactive material license does
not allow radioactive material use on human
beings.
10
Notice to Employees
Copies of State and Federal radiation safety
regulations, licenses issued to the university of
Missouri-Rolla and documents related to operating
procedures applicable to licensed activities are
available for review at the Environmental Health
and Safety Department (Health Physics Office) 108
Campus support facility. Laboratory inspection
reports and dosimeter reports are also made
available for review at the same location.
11
Reporting Concerns or Violations
If you suspect that a radiation safety violation
has occurred, report the violation to your
supervisor. If you believe that adequate
corrective action has not been taken, notify Ray
Bono, RSO, at 341-4305. You may also notify
Dr.Mark Fitch, chair of the RSC. If you feel that
the violation has not been resolved you should
read the NRC Form 3 Notice to Employees for
further instructions.
12
Continue
This form is available at http//www.nrc.gov/NR
C/FORMS/form3_us.html and is also posted in each
authorized laboratory.
13
Whole Body Dosimeter
A Luxel tm dosimeter is used to measure an
individual's whole body dose equivalent (DE).It
can detect x- and gamma radiation above 1 mrem
and high-energy beta radiation above 10 mrem. It
can not detect radiation emitted from low-energy
beta emitters such as H-3, C-14 or S-35.A Luxel
TM dosimeter is required if you routinely handle
high-energy beta emitters. For those
individuals who require a neutron exposure
monitor a special film badge is issued in place
of the Luxel Dosimeters.
14
Ring Dosimeter
A ring dosimeter is used to measure an
individuals extremity dose equivalent.It can
detect x- and gamma radiation above 30 mrem and
high energy beta radiation above 40 mrem. A
ring dosimeter is required if you routinely
handle high energy beta emitters .
15
Dosimeter Adds and Changes
For information regarding dosimeter requests,
changes or cancellations contact Ray Bono at
341- 4305 or by e-mail rayb_at_umr.edu
16
Dosimeter Guidelines
Wear your whole body dosimeter on your upper
torso in the area likely to receive the highest
dose. Wear your ring dosimeter with your name
facing outwards on the hand likely to receive the
highest dose. Wear your ring dosimeter
underneath your disposable glove.
17
To avoid Inaccurate Dosimeter Readings
Internal dosimeter elements should never be
removed from the protective plastic dosimeter
case. If your dosimeter becomes lost or damaged,
notify the RSO at 341-4305. Dosimeters should
not be exposed to non-occupational radiation
exposure such as medical or dental x-rays. Store
your dosimeter(s) away from sources of ionizing
radiation when not in use.
18
Dosimetry Reports
A report is generated showing the whole body Dose
Equivalent (DE) received for each month your
dosimeter was worn. X-ray or gamma-ray DE may be
indicated by a P in the radiation quality
column. DDE indicates a whole body dose from
penetrating radiation, LDE indicates a lense of
the eye dose, and SDE indicates a skin or hand
dose.
19
Continue
A Luxel dosimeter exposure of lt1 mrem for x-ray
or gamma-ray exposure and lt10 mrem for high
energy beta exposure for the month will be
indicated by an M for minimum reportable
quantity. M for ring dosimeters is lt30
mrem. Dosimetry Reports are available for review
at the EHS office, 108 Campus Support Facility.
20
Records to be maintained
Most records required by State or Federal
regulations are maintained by the ( EHS)
Radiation Safety Office. Some required records
cannot be maintained there. One of the records to
be maintained by the campus Radiation Safety
Office is the quantity of radioactive material
currently authorized. For federally controlled by
product material, the campus is authorized to
posses and use specific quantities of these
materials with the aggregate of all such
materials not exceeding a specific limit.
21
Continue
Thus, the current inventory of each radionuclide
and the aggregate sum of these individual items
must not exceed the limits set by the
license.What the individual investigator must do
is keep a record of the receipt, use, storage,
and disposal of radioactive materials so that at
any time, the amount on hand can be calculated.
22
Waste Disposal Procedures
Most of the information about disposal of
radioactive wastes of importance to the
individual investigator is contained in section 4
of the UMR Handbook of Radiological
Operations.The link to this section of the
Handbook is http//www.umr.edu/ehs/radiological/
umrhandbook.htmlHROIIF4 It is recommended that
you review that section. The only method of
disposal left to the discretion of the
investigator is that by release to the sanitary
sewer system, and this is limited to quantities
released incidental to cleaning glassware.
23
Continue
All other disposal must be done by EHS.
Additionally, any material transferred to EHS for
disposal is to be identified as to type, form,
quantity of radioactive material, and hazardous
waste category in accordance with the campus
Hazardous Waste Regulations. Such a record should
be made in the users inventory log as well.
24
Posting of Warning Signs and Notices
Part of the State and Federal regulations with
witch the campus must comply stipulate a system
of warning signs and notices to be posted.
Samples of these warning notices are available
from the EHS department. A copy of the current
version of Form NRC-3 Notice to Employees must
be posted in every laboratory using by product
materials licensed by the NRC. This form is to be
posted so that every employee of the laboratory
can read it. Copies of this form may be obtained
from EHS.
25
Continue
Rooms in which radioactive materials are to be
used on a routine basis will be identified by
affixing to the entrance doors a warning sign
containing the words "Caution -Radioactive
Material"and including the three-bladed,
radiation symbol, as required by 10 CFR 20.1902
and 20.1903. Other wording appropriate for the
use of the room may be added, but nothing less
than these words with the symbol is acceptable.
Regardless of the presence of the warning labels,
the investigator shall secure the material from
unauthorized access.
26
NRCs regulations (in 10CFR19.12, "Instructions
to Workers ").
  • The NRCs regulations (in 10CFR19.12,
    Instructions to workers) require that licensees
    instruct individuals working with licensed
    radioactive materials in radiation protection as
    appropriate for the situation.
  • Regulatory Guide 8.29 Provides Instructions
    Concerning Risks from Occupational Radiation
    Exposure .
  • ( http//www.nrc.gov/NRC/RG/08/08-029.pdf )
  • Regulatory Guide 8.13 Instruction Concerning
    Prenatal Radiation Exposure(http//www.nrc.gov/NR
    C/RG/08/08-013.html ). Supplements Regulatory
    Guide 8.29.

Laboratory, Radiation Emergency Procedures
Laboratories where radioactive material is used
must be posted with a copy of the UMR "Radiation
Emergency Procedures". A copy of the Radiation
Emergency Procedures is available at the
following URL http//www.umr.edu/ehs/radiologica
l/healthphysics.htmlHPEPLA7
28
Instructions for users of Radioactive Materials
Section 5.0 of the UMR Handbook of Radiological
Operations, covers the requirements for use of
radioactive materials at UMR. http//www.umr.edu/
ehs/radiological/umrhandbook.htmlHROV In
particular you should note that (EHS) Radiation
Safety must be notified before purchasing
radioactive materials. The individual users shall
also keep a current inventory of all radiation
sources being used and shall keep this record in
a form that permits convenient review by EHS or
by a representative of the NRC.
29
Area Monitoring
Each laboratory shall have a survey meter and in
some cases, an area monitor (e.g., area film
badge) readily available, capable of detecting
radiation from the material in use.
(Laboratories using small quantities of weak
beta emitters such as H-3 or C-14, exclusively,
are exempted from this requirement. Before each
use of the survey meter, check to see that the
calibration is current (Located on the side of
the meter), also check the batteries. Notify EHS
for calibration and repairs if needed. For
further monitoring requirements visit the
