Preliminary discussions withMr; Cari D.Jeffries,Director,‘and
Robert P. Ball, M.D., Radiologist, “dndicate that there existsat the
Oak Ridge Hospital exceptional opportanities| fora pilot study of the
actual exposure from diagnostic procedures....For each type of diagnostic
examination at Oak Ridge Hospital a ‘standard set of pictures is made
and the milliampere setting and thetine”and Voltage used are’recorded
‘for each.
At the present time it.‘eppears”‘that coupletely | reliable
records are available for 30,000to 35,000exposures. From the data
it will be possible » With a few additional dosimetry measurements, to
make an estimate of dose for each exposure.”;In addition, the program
of x-ray work at the Oak Ridge’Hospital canprovide indefinitely a ..
contiming standard recording of all. diagnostic exposures. From these
records the dose calculations can readily be made. The standard
recordings have been consistentlykeptsince October, 19526
In connection with ‘obtaining data of ‘interest to‘the Health Physics
Division, ORNL, D. M. Davis and E. De Gupton have made some limited
phantom studies utilizing the Oak Ridge Hospital facilities. ORNL
might be able to furnish some additional dosimetry measurements, but
we believe outside resources. would have1to be| Brovided for

We recommend that a member of yoar staff.“come ‘to ‘Oak Ridge and discuss
plans for setting up the pilot study proposed. Dr. C. 8S. Shoup and
