[ RadSafe ] UN2910 Labeling for EXEMPT Calibration Sources - Yes orNo

[Dan W McCarn]

Dear Group:

 

Cary stated: Based on 49 CFR 173.436; IATA 10.4.2.1; The total for all
sources is ~96% of the exempt consignment limit – “i.e. you do not have
radioactive material
”

supports this view.

 

The combined activity does not warrant any special handling, as Cary pointed
out.

 

Cary appears to be correct! If so, I do not need to label anything. 

 

Is this the consensus?

 

To be clear to all, I am moving from France back to the USA. These are
calibration sources for a 1024 channel MCA / spectrometer using a 3x3"
NaI(Tl) detector. I included them as a UN2910 labeled package in my
household shipment from the USA to France, no one seemed to question it, and
the bill of lading for the shipment reflected that. They are lead shielded
(about 9 cm length x 6 cm diameter with a 1.25 cm wall thickness) and the
sources themselves are labeled according to USNRC regulation.

 

As an aside, the activity from the surface of the lead shield (Ludlum Model
19):

0 cm is 150 uR/hr

15 cm is 23 uR/hr

25 cm is 16 uR/hr

50 cm is 11 uR/hr

100cm is 10 uR/hr

Background activity is 9 uR/hr;

   All exempt sources must have a label, see attached generic label.

   Must have per USNRC regulation for distribution.

   Yes, we are also have difficulty with carriers.

   Countries are creating new internal rules that may differ from
international accepted rules and regulations.

   Some require prior permission, others delivery to air port only.

   Some of these are published in the IATA regulation, per ICAO guidelines.

   If you have a specific country, let me know, I may be able to assist with
rules.

Your total activity is under the exempt consignment limit for DOT and ICAO:

49 CFR 173.436; IATA 10.4.2.1

The total for all your sources is ~96% of the exempt consignment limit –
i.e. you do not have radioactive material
 

 

(not sure how well the table will survive
)

Dear Group:

 

As I understand it, exempt calibration sources are covered under the UN2910

labeling guidelines; is this correct? Or are they exempt from labeling as

well? 

 

I was just informed that one shipping company does not handle any material

labeled as UN2910.

 

The sources are labeled on the Spectrum Techniques invoice as CALIBRATION

STANDARDS.  

 

The activities are as follows:

 

1.0 uCi Ba-133 ..

1.0 uCi Cd-109 ..

1.0 uCi Co-57 ..

0.1 uCi Cs-137 .. (note that this is the new exempt standard for Cs-137)

1.0 uCi Mn-54 ..

1.0 uCi Na-22 ..

1.0 uCi Co-60 ..

1.0 uCi Zn-65 ..

 

So
 being exempt, do they require labeling?
