textbook correct?

["DAVE GILMORE" <DGILMORE@navajo.astate.edu>]

Hello Radsafers,
Some of you are likely to be intersted in answering this question.  I 
am preparing a lecture for my genetics class on cancer.  The textbook 
I am using summarizes the chapter by saying that a number of external 
factors, "including medical and dental x-rays...play significant 
roles in cancer development."  
    Somehow, from the various threads I have been following, I get 
the feeling that such x-rays are of low dose, and low doses have no 
harmful effects.  Is there any evidence that the doses received from 
modern medical and dental x-rays play a "significant role in cancer 
development"?
    Thanks for your opinions.
