Re: Radiation monitoring badges in cine/floro exams

[David W Lee <lee_david_w@lanl.gov>]

But it is also important to point out that NRC rules do not apply to
virtually all U.S. cine/fluoro environments which normally use x-ray
machines which the NRC is not authorized to regulate!  Thus, within the
non-NRC x-ray world, the issue still remains.  It is the NRC's lack of
regulatory authority in this arena that has forced the Agreement States to
try to compensate and fill this regulatory gap.  The State of Texas, as one
Agreement State example, has made a good effort in this respect.  It is
probably inappropriate to try to follow NRC dosimeter placement guidance in
areas where the NRC, itself, has no regulatory authority.  For example, in
the NRC-world, most users of radioactive material do not wear lead aprons.
