[ RadSafe ] UN2910 Labeling for EXEMPT Calibration Sources - Yes or No

The proper shipping name for UN2910 is:  "Radioactive material, excepted package-limited quantity of material."  To ship under this category, the material must meet specified quantity and dose rate limits.  Also, the hazmat employee training requirements of 49 CFR 172 apply to this category.

Subject: [ RadSafe ] UN2910 Labeling for EXEMPT Calibration Sources - Yes or No

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

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

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?
