Re: transportation event
If you want to see a typical Type A package in which
nuclear medicine material is shipped, see Figure 11E
on page 34 of the pdr document located at
http://hazmat.dot.gov/pubtrain/ramreview.pdf
On the previous page it says the contents can be up to
270 mCi. They are easy to open by just pulling on the
handle.
Typical nuclear medicine syringe shields look like
these

At least they screw together.
