Radioactive Materials at Union College.
The following provides a
comprehensive discussion of the regulatory control of
radioactive materials at Union College. Figure 10-1 is a Flow
Diagram for the Radioactive Materials at Union College.
The following numerical listings are referenced to this Figure
10-1.
-
Purchase Isotope
(Training)
The radioactive
materials are purchased following the normal procedures
established by the Purchasing Department at Union College,
except that radioactive materials require the signature of the
RSO on the Purchase Requisition as outlined in Section 10.01.
At this time the RSO
personnel enter the radionuclide in the RSO computer program for
radioactive material inventory. See Figure 10-2, "RSO
Inventory." The individual purchasing the radioactive
materials or ionizing radiation producing machine must have met
the radiation protection training requirements set forth in
Union College's "Radiation Safety Regulations and
Procedures," Section 16.00, "Radiation Protection
Training."
-
Receiving
When the purchased
radioactive material arrives at Union College through the
Receiving Department, personnel follow the guidelines
established in Section 10.02 (7) to distribute the ordered
materials.
-
User
When the user receives
the material from Receiving, he is requested to enter the
radionuclide into his or her inventory and follow Section 10.05,
"Opening of Package Containing Radioactive Materials"
and complete Form 10.2.
-
Experimental Use
The radioactive
materials are most likely used in tracer experiments at Union
College. Depletion of User's inventory can occur in 3
ways.
-
Radioactive decay of the
radionuclide: A(t) = A(0) e.-kt
-
Radioactive material
used in experiments. This refers to experimental losses
due to counting of samples, etc.
-
Placed in Radioactive
Waste Receptacles for careful disposal.
-
Radioactive Waste
Receptacles
All radioactive materials
placed in Radioactive Waste Receptacles, both liquids and solids,
must have analyses of the waste maintained at the receptacle.
These analyses must include
-
Radionuclide
-
Quantity (µCi)
-
Chemical Form
-
Physical Form
-
Accompanying Chemicals
-
Laboratory of Origin
The appropriate tag must be
affixed to each container.
-
Only liquids containing
H-3 or C-14 will be accepted by the RSO, and an analysis must be
provided.
-
Only stable radioactive
materials will be accepted by the RSO for shipment to a Waste
Disposal Site by a vendor. No pyrophoric materials,
nitrates, strong acids or bases are acceptable.
Consultation with the RSO is strongly recommended.
-
Radioactive Waste Pickup
The RSO will provide a
biannual pickup of radioactive waste for all users. This
pickup usually occurs once in the first term and once in the third
term. All waste is transported by Physical Facilities to the
Radioactive Waste Management Area. Normally, the Principal
Investigators will be responsible for placing radioactive wastes
from their laboratories in the Radioactive Waste Storage cabinet.
-
Radioactive Waste
Management Area
The Radioactive Waste
Management Area is utilized to prepare samples for storage for
radioactive decay (half lives less than 90 days) and for packaging
for licensed vendor disposal. Storage for disposal by decay
requires holding the radioactive materials for at least 10 half
lives [0.001A(o)] and then monitor before disposal to normal trash.
10.01
Procurement of Radionuclides and Transportation of Radioactive
Materials
Because of the licensing
requirements of the New York State Department of Health, it is necessary
that inventories of radionuclides be maintained by both the Office of
the Radiation Safety Officer and the Radiation Installation
Supervisors. The procedure that must be followed for procurement
of radionuclides is given below.
10.02
Procedure for Procurement by Union College Purchase Order
-
The Supervisor of a
Radiation Installation in which radionuclides are used initiates a
purchase order (PO) for the radionuclide(s) under Union College's
Specific License.
-
Before the purchase order is
forwarded to the Purchasing Office, it must be approved by the
Radiation Safety Officer.
-
If the inventory allows
purchase of the requested radionuclide(s) without exceeding the
licensed quantity of the specific radionuclides, and if the
requester has up-to-date training, the Radiation Safety Officer
indicates approval on the purchase order and signs this approval.
-
The purchase order is
returned to the Requester for further processing in conformance with
the Purchasing Office.
-
If the proposed purchase
will result in an inventory in excess of the quantities stipulated
in the license, or training is not up-to-date, the requisition is
returned to the Requester with the reason why it is not acceptable.
The Requester must revise the requisition or receive the required
training and resubmit the requisition to the Purchasing Office.
-
The Purchasing Office
processes a purchase order after receiving approval of the Radiation
Safety Officer.
-
When the shipment arrives at
the Union College Receiving Department, that Department notifies the
purchaser by telephone and then either delivers the material or has
the purchaser pick it up without delay. If delivered, it is
done so on the first available Union College vehicle. If there
is visible damage to the container, the shipment will be held at the
Receiving Department and the Radiation Safety Officer will be
notified. The package will not be released until examined by
the Radiation Safety Officer or the requester.
-
The Radiation Safety Officer
will verify all Installation Inventories by providing a yearly
computer printout that the Installation Supervisor will verify.
10.03
Procurement Other Than Union College Purchase Order
No sources of radiation
(machines or radioactive materials) may be brought to the Union College
campus without prior approval of the RSO. Verbal requests by a
Radiation Installation Supervisor and verbal approval must be
immediately followed by written requests and approvals. As a
minimum, approvals require coverage of the source by an existing
registration or license.
10.04
Transportation of Radioactive Material
Form 10.1,
for intracampus transportation of radioactive material should be
completed and attached to the SD100. Upon request, the RSO will
provide assistance in completing Form 10.1.
Shipment of radioactive
materials (including any device containing radioactive material as a
sealed source) to an off-campus destination must be arranged, a release
must be obtained from the RSO, and as a minimum must conform to 49 CFR
Parts 1199 title, "Transportation," which is available in the
Radiation Safety Office.
Transportation in privately
owned vehicles is discouraged since it is at the vehicle owner's
risk. The material must be in a container that meets the U.S.
Department of Transportation Regulations set forth in 49 CFR Parts 1199
"Transportation" in any vehicle.
The safety of the shipment of
radioactive materials depend on 3 items of conformance:
-
Proper Packaging
-
Proper Labeling
-
Proper Bill of Lading
The Code of Federal Regulation
title 49, "Transportation," provides authoritative guidance in
each of the above areas.
10.05
Opening of Packages Containing Radioactive Materials
-
Receiving
-
All packages received at
Union College are delivered to Central Mail.
-
Receiving personnel
visually inspect the package for any sign of damage (i.e.
mechanical damage or water damage). If no damage is
observed, the package is either sent via a Union College vehicle
to the User's Laboratory or is picked up by the purchaser.
-
If the package shows
signs of damage, the RSO is notified and a staff person, with
the User Laboratory Supervisor, completes Form 10.2 and follow instructions
below.
-
Record all information in
Item 1 of attached Form 10.2, "Radiation Survey Radioactive
Material Receipt Form."
-
Place unopened package on
absorbent paper with plastic backing down. Record package
condition in item 2. (If damage is observed, notify the RSO.)
-
Note radioactive material
label on package and check appropriate box in item 3.
-
Using the appropriate
radiation survey meter, record the radiation levels of the package
surface and at 1 meter and record on item 4. [If level of
10CFR49 are exceeded (Table 8) notify the RSO.]
-
Take swipe of each surface
of the unopened package and count in the Automatic Sample Changer as
per procedure. (If samples exceed 1000 dpm/swipe, notify the
RSO.)
-
Open the package carefully,
saving all contents. Take swipes of inner container and
packing materials and count in the Automatic Sample Changer as per
procedure. (If samples exceed 1000 dpm/swipe, notify the RSO.)
-
The laboratory supervisor
should compare the information on the packing slip and the label on
the inner radioactive material container, assure they agree,
and record results in item 6.
-
Packages that have met the
above criteria may be released to the ultimate user.
-
Packages not released shall have
their final disposition determined by the RSO following discussions
with the vendor/supplier and/or the NYSDOH personnel.
-
The Radiation Survey Form
shall be signed and dated by the person doing the survey in item 8,
and retained by the receiver.
-
All packages and packing
material free from radioactive contamination should be disposed of
as normal trash. Make sure all radiation or radioactive labels
have been removed or destroyed.
