Re: mrad silicon

     Usually output of X-ray machines/devices are usually expressed in 
     mR/mAs, R/min...etc.  I have never known output of x-ray systems 
     expressed in mrads silicon.  If you are calculating the shielding for 
     an x-ray system, you will need to know the workload (e.g mA-min).  
     Don't know where mrads silicon would apply.

Hi all.
     
In investigating the output of a 2.5 MeV flash X-ray machine, someone 
expressed the output in terms of "mrads silicon". I'm not familiar with 
that term. Could someone please explain it to me? Absorbed dose in 
silicon? Important bec were calculating concrete shielding thickness?
     
Beam measurements were made with TLDs, if that helps.
     
Thanks in advance.
