It seems extremely unlikely.  The article, including Brenner's remarks, are
pretty "nuanced" 
and don't actually say anything definite about the exam or the radiation
dose delivered.  It is 
possible that the "151 scans" are actually 151 *slices* of 1 mm each,
acquired in one or two 
passes with a multislice scanner.  The article may simply be designed to put
public pressure 
on the hospital to $ettle quickly.

If dose implied by the "red marks all the way around his head, like a severe
sunburn" 
statement were true, the child would be dead or very sick.  At least, if the
erythema is 
radiation induced there should be some epilation also, but there is no
mention of that in the 
article.

I wonder if it is possible to do EPR dosimetry on human hair?

Hallo friends,

does anybody know about this?
http://www.diagnosticimaging.com/news/article/113619/1348813

Any idea of how it could happen (if it really happened)?

Thanks!
