Usually available in the Rad. Therapy Dept.  I've used it to document fluoro
fields on pregnant patients to help with fetal dose estimates on patients
requiring special procedures.   The film was able to measure up to 24 R
entrance exposures at fluoroscopic energies.  I recently read a paper that
used some other films with a higher top end and they also demonstrated a
body temperature effect which I did not correct for.  It was either in the
Med Physics or Health Physics Journal, I believe.  The nice thing about
film, is that it documents all the fields and allows you to find the highest
exposure point as well as any other points of special interest.  You also
might want to check out this reference, which I used to set up my system:
Health Physics, Vol. 59, No. 3 (Sept '90), pp. 295-298, by R.A. Geise and
H.J. Ansel.
