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?
