Here is a question, does the TI include neutron dose rate contribution? 
During a 'recent' class on transportation, when asked, the instructor 
said no, just photons. He said the DOT (or NRC...) had made a ruling on 
that... though, he could not recall exactly where that was. The regs say 
mSv/hr divided by 100 (mrem/hr) (49 CFR 173.403). 

Anyone out there measure the neutron component, of say a moisture density 
gauge or other neutron sources?
