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

[Cary Renquist]

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...)

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

 

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?
