Ref. No.: 10-0039R
Dear Mr. Ali:
This responds to your letter concerning whether it is a violation ofthe Hazardous Materials
Regulations (HMR; 49 CFR Parts 171-180) to place the RQ designation on a Dangerous Goods
Declaration for "Iodine 131" (131) shipped by aircraft under the HMR.
According to your letter, a small percentage of your company's product is shipped by aircraft via
FEDEX. For these shipments, you use a Dangerous Goods Declaration, as packages are classed as
Radioactive Yellow II or Radioactive Yellow III. The main radionuclide your company ships is
"Iodine 131" in a liquid compound form. When shipping "1-131" in amounts greater than 1 0
millicuries (0.37GBq), you use the RQ designation on packages and shipping documents in
compliance with the definition in § 171.8 for hazardous substances listed in § 172.1 0 I, Appendix A,
Table 2. You ask if your understanding is correct that since the amount being shipped is greater than
the RQ for "1-131" [0.01 Ci (.00037TBq)] and qualifies as a hazardous substance, the HMR requires
that you include the RQ designation on the Declaration ofDangerous Goods document.
Your understanding is correct. Based on the scenario described above, you are shipping a hazardous
substance as defined in §171.8 since 1-131 is listed in Table 2 to Appendix A in §I 72.101 and you are
shipping in a quantity in one package in excess of the reportable quantity listed in the table. Thus, the
letters "RQ" are required to be entered on the shipping paper per §1 72.203( c )(2) and shown on the
package per § 172.3 24(b).
I hope this satisfies your inquiry. If we can be of further assistance, please contact us.

Mr. Edward Mazzullo
Office ofHazardous Materials Safety Administration
US Department of Transportation
122 New Jersey Ave SE
Suite E 21316
Washington, DC 20590
Dear Mr. Mazzullo:
My name is Ken Ali and I am the Radiation Safety Officer at Nuclear Diagnostic
Products(NJ State License 10649/01 and fonner NRC Lic. # 29-30500). This is a
commercial nuclear pharmacy located in Rockaway New Jersey, producing radioactive
diagnostic imaging drugs for Nuclear Medicine departments at hospitals and other
medical institutions.
A small percentage ofour product is shipped via FedEx in which case we use a
Dangerous Declaration F onn, as packages fall under the DOT classification as
Radioactive Yellow II or Radioactive Yellow III. The main radionuclide we ship by this
method is Iodine 131 in a liquid compound fonn. When shipping 1-131 amounts greater
than 10 millicuries,(0.37GBq)-we use the designation RQ on the package as well as on
the shipping manifest /Dangerous Goods Declaration Fonn. This is in compliance with
table 2 of49CFR 172.101 that the Reportable Quantity for Iodine 131 is 0.01 Curies(1 0
millicuries )or (0.37GBq).
It is my interpretation that since the amount being shipped is greater than the RQ amount,
the material in question now qualifies as a Hazardous Substance under the definition set
forth in Section 172.101 paragraph 6 and table 2 and section 171.8-Hazardous Substance
paragraph 2.
On Wednesday January 20, 2010, the Federal Aviation Authority inspected this facility
and found no violations. As part ofthe general counseling and discussions about fonns
and changes in the future, we discussed the placement ofthe letters RQ on the Dangerous
Goods Declaration fonn. Subsequent to the Inspector's visit I received a communication
from him stating that he did not advise using the RQ designation for Class 7 RAM
(Radioactive Materials)on the manifest. To support his rationale, the inspector cited the
interpretation ofPHMSA document Ref.# 05-0247R
101 Roundhill Drive
RockawaYt New Jersey 07866
(973) 664-9696
(973) 664-9699 Fax

I was of the opinion that the inspector did not take into consideration the amount (in
millicuries) ofmaterial being shipped, which automatically qualifies it as a Hazardous
Substance. This is so based on quantity only, regardless ofpresence/absence ofany
specific chemical or other harmful properties and must be designated by the RQ marking
on manifest as well as the package.
On January 22. 2010, I spoke to Andrew and later Rob from your department who agreed
with my interpretation ofthe requirements ofthe regulations with reference to the
directive ofReference letter 05-0247R.
In a conversation earlier today 112612010, the FAA inspector still maintains the position
that the RQ designation is not necessary on our packages even when the radioactive
material Iodine 131, being shipped exceeds the RQ value of 0.01 Curies.
While I have the utmost respect for the rule and interpretation ofthe letter of the law by
the regulatory agencies, I do sincerely believe that there is a slight misinterpretation by
the FAA Inspector of the content of your ruling 05-0247R and its applicability to product
being shipped from this facility.
Your written guidance is now sought as to whether we should continue with the pmctice
of identifYing RQ amounts on manifests and packages containing greater than
0.0ICuries(0.37GBq) ofIodine 131, offered for shipment, which my humble
interpretation supports, or whether we should discontinue such practice based on the
content of your directive Reference 05-0247R.
