Dear Ms. Cahill:
This is in response to your email dated April 18, 2014, requesting clarification of the
Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) relating to the
transportation requirements for radioactive surgical specimens. You state that your
radioactive specimens have an activity of 1.0 millicuries or less prior to injection, and after
injection there is some residual in the syringe. You state that there will be less than 27
millicuries of Technetium-99m (Tc-99m) by the time the driver would handle any
radioactive material. Your questions are paraphrased and answered below:
Q1: You ask if training for personnel and couriers must comply with the training
requirements found in Subpart H of Part 172 of the HMR.
Al. Section 173.436 sets activity concentrations for exempt material and activity limits
for exempt consignments. The activity limit for exempt consignments of Tc-99m is less than
.27 millicuries. If the only radionuclide present is Tc-99m, and the total activity in the
consignment is less than either the activity concentration limit or the activity limit for
consignments shown in § 173.436, that consignment would not be considered to be a
radioactive material under the HMR. Assuming the specimen does not meet the definition of
any other hazard class, the material is not regulated as a hazardous material and none of the
training requirements of Subpart H of Part 172 of the HMR are applicable.
Q2.
Surgical specimens containing Tc-99m can be transported from one RAM licensed
facility to another licensed facility as stated in the licenses?
A2. The licensing you mention does not appear to be an HMR requirement. Please direct
this question to the appropriate authority.
Q3. Must specimens be labeled with a radioactive material label until the less than .27.
millicures activity limit is met for "exemption"?

<<<PAGE 2>>>

A3. If offered as a fully regulated radioactive material under the HMR, yes, labeling
would be required. Depending on the activity present (see § 173.425), your specimens may
qualify to be offered as Radioactive material, excepted package-instruments or articles, UN
2910 and further excepted from labeling as a radioactive material.
Q4. Until a specimen reaches the "activity limit for exempt consignment" in accordance
with § 173.436, there is no requirement for radioactive labeling?
A4. See Al.
I trust this information is helpful. If you have further questions, please do not hesitate to
contact this office.
Sincerely,
Shane C. Kelley

Dear Mr. El-Sibaie,
I have been in contact with Michael Conroy (Sciences Branch / Division of Engineering and Research / Office of
Hazardous Materials Safety)
in regards to an issue which needed expedient clarification, so as to not delay patient care. I realize an official position
response can take 6-8 weeks. With his guidance (as shown below with our emails), I believe we do have the clarification
necessary and am now requesting the "official position" written interpretation to satisfy administration.
My question to Mr. Conroy and now you, is in regards to the handling, labeling & transport of radioactive surgical
specimens. I have done extensive research and been in communication with the MASS DPH/Radiation Control Program,
MASS DOT and now the US DOT. If you can confirm the information below, I would appreciate it greatly.
From the information gathered, I am lead to believe:
1.) Radiation safety training for our personnel and couriers, "for handling & transporting" Tc99 radioactive surgical
specimens can be provided in-house by our medical physicist.
Note: (Specimens will have an activity of 1.Omillicuries or less, at the time of injection, there is some residual in
the syringe that is not fully injected. There will be less than .27millicuries by the time the driver would handle the
container.)
2.) for radiation & transportation purposes, radioactive surgical specimens containing Tc99m, can be transported
from one RAM licensed facility to another licensed facility as stated in the licenses.

3.) the specimens must be labeled with a radioactive material label UNTIL the less than .27 millicures activity limit is
met for "exemption".
4.) when the specimen reaches the "activity limit for exempt consignment", in this case Tc99m, less than
.27millicuries, in accordance with 49 CFR 173.436, there is NO requirement for radioactive labeling,
5.) NOR is there a requirement for DOT HAZMAT training for "exempt consignment" material for personnel handling,
packing or transporting.
6.) FYI: Until the "less than .27mCi activity" is confirmed, the specimens will be securely stored in a leaded "transport
container" in the Nuclear Medicine hot lab satisfying the UN2910 less than .5mR/hr at the surface of the container.
Please advise and respond by email at your earliest convenience, as time is a concern for us in providing safe & quality
patient care.
Thank you for taking your time to assist me in this matter.
Respectfully submitted,
Debbie

Dear Mr. Conroy,
I appreciate your prompt response to this matter and have submitted a "written interpretation" request.
RE: Figure 2: UN2910 is for "transport container" from the OR to NM and storage in the secure hot lab only, until the
exempt consignment activity is reached. It will not leave the facility. Nothing but specimens confirmed as "exempt
consignment" will be transported via courier, requiring no radioactive labeling or additional HAZMAT training for
personnel.
Thank you for your assistance and clarification.

Subject: RE: Tc99m Activity limit for exempt consignment.
Debbie-
Please note: This is not an official "DOT position." If you wish to obtain an "official position", this should be done by
requesting a written interpretation from the Director of the Office of Hazardous Materials Standards, following the
directions in 49 CFR 105.20(a)(4).
If I understand your question correctly, you want to know what the DOT requirements are for shipping a specimen that
contains less than .27 millicuries of Tc-99m.
You are correct that the "activity limit for exempt consignment", in this case Tc99m, is less than . 27millicuries, in
accordance with 49 CFR 173.436.
Please note that the exempt limit is for the "consignment", so if there are multiple specimens in a consignment, you
would need to look at your total activity in all of the specimens in the consignment to see if you are still exempt.
("Consignment" means a package or group of packages or load of radioactive material offered by a person for transport in
the same shipment.)
If the only radionuclide present is Tc-99m, and if the total activity in the consignment is less than either the activity
concentration limit OR the activity limit in the table in 49 CFR 173.436, that consignment would not be considered to be a
radioactive material under DOT's Hazardous Materials Regulations (HMR) and no marking, or labeling would be required
for transport purposes as radioactive material. (Other non-transportation regulations (e.g., NRC, EPA, OSHA) may apply
however.) If that is all you are preparing for shipment, since it is not regulated under the HMR, there would be no training
required under the DOT HMR.
I am confused by Figure 2 in one of your attachments that shows a UN2910 label. If you are shipping the exempt
quantities you describe, that label would not be proper to use. In addition, that is not a DOT label, but is an ICAO label and
would only be needed if you were shipping a non-exempt, excepted package by air (as evidenced by reference to
"Captain" at the bottom of the label). If your consignment quantities exceed both the exempt limits cited above, but were
less than that required to be shipped in a Type A package, they would only need to be marked with UN 2910 (see 49 CFR
173.422) with no label - you'd add the candy-stripe label for shipping such excepted packages by air.
IF there are other materials in the shipment that are considered hazardous materials under the HMR, you would need to
consider how to properly comply with the HMR for those substances, including training. The information you provided
indicates that your specimens would be shipped with formalin. Please note, I am NOT the right individual to answer
questions on classes other than Class 7, radioactive. If you go to the Hazardous Materials Table in 49 CFR 172.101, you
will see an entry for Formalin which will direct you to the entry for Formaldehyde. I am attaching a recent rulemaking that
addressed shipping formalin. Also, here is a link to a non-DOT article (I cannot vouch for its accuracy!) that addresses
shipments of formalin that you might find useful:
http://www2.mlo-online.com/features/201204/education-and-training/formaldehyde-shipments-avoid-potential-pitfalls-
lab-safety.aspx
It indicates that depending on the particulars of your shipments, you might be subject to the HMR, including training
requirements.
