My shift in subject (still CT) from the "criminal" who overdosed with CT  

to the great benefit from CTs and lack of harm from ~ year background radiation 

(even less risk of cancer), seems to have been lost in the translation to Austrian. 

Sorry, Franz.

What happened to this criminal? Was he hanged publicl        y or was he just 
told not to do this again??????? Due to the many "Westeners" at the cinema 
we know very well, that horse thiefs were hanged immediately - whether they 
were guilty or not..... The same was of course for people who killed others. 

Expecting a reasonable answer

Howard Maccabee, PhD, MD radiation oncologist, 

 needed thousands of CTs to accurately locate cancers 

he burned out (prostate, breast, etc). 

He responded to, "one of the most important -- but most frightening 

 -- articles I've read  " in "Cancer Risks Associated with CT Scanning" 

 Dachs, American Family Physician, 81,2,1/15/10, 111-114, referring to 

 Computer Tomography - An Increasing Source Of Radiation Exposure, 

Brenner, NEJM 2007,;357,22. 

Entertain and enlighten a meeting of health physicists with 

his half-hour presentation (DVD available from; 

DDP 1601 N. Tucson Blvd # 9 Tucson AZ 85716, 

ddponline.org, or 520 325 2680). 

 For example, new background radiation data adds 

av. 20 mSv (0.2rem) from radon, so 1 CT has < 2 years 

of usual background radiation - and where most radiation - least cancer. 


Maccabee refutes, with excellent slides, the Brenner-Dachs fearmongering.

 "over doses" 


The techs are taking a beating on this, but its the docs and the 
physicists who screwed up.   Of course we are talking about diagnosing a 
stroke in progress so the pressure to use the technique even in doubtful 
situations must be overwhelming.  Still, not understanding the output 
parameters of the new equipment is unforgivable.
