I have looked at the internal emitter studies using laboratory 
beagles (both high LET and low LET radiation emitters) and compared 
them to available human data. None of these studies follow an LNT 
dose-response. In fact, they all show a lifetime effective threshold 
below protracted lifetime doses to the target tissue that is less 
than about 10 Sv (1000 rem). [See my Chapter 30 in "INTERNAL 
RADIATION DOSIMETRY" (O.G. Raabe Ed.), Medical Physics Publishing, 
Madison WI 1994).
