Industrial radiography and computers

[Ken Smith <ksmith@cats.ucsc.edu>]

Hi All - 

We are going to have a number of exposures taken of floors and walls in one
of our science buildings.  The purpose of the radiography is to determine
the location of cables in the post-tension cement beams, to avoid them
during a drilling operation.  We are contracting a local firm to perform
the radiography. 

There has been some mention of removing any computer CPU's and magnetic
storage devices (disk drives) in the near (40 ft') vicinity of the exposures.

Do you know of any references that I can research?
Has anyone personally experienced problems with computer storage loss by
radiography exposures?

(The source that will be used is a ~65 Curie Ir-192 source)

Thanks in advance for any responses - please reply to my e-mail below
unless you thing it interesting to the entire list.
