I does not matter if the state is an agreement state or non-agreement
state unless the individual is exposed radiation from NRC regulated
materials in addition to machine sources.  The state radiation control
agency has jurisdiction over the use of x-ray producing machines. 

Wes Dunn's answer is correct.

Now for a twist.  If the radiologist receives 4000 mrem at hospital A 
between 1/1 and 11/30; 1000 mrem at hospital 2 between 12/1 and 12/31; 
and 10 mrem at Hospital III between 12/1 and 12/31; who has overexposed 
the worker?
