Dear colleagues,

Nevertheless I didn't get any information on my request, I would like to
inform that I found the bibliography where the data was published:
The Medical Basis for Radiation Accident Preparedness, Karl F. Hubner and
Shirley A. Fry, ELSEVIER/NORTH-HOLLAND, 1979 - Proceedings
of the REAC/TS International Conference:  The Medical Basis for Radiation
Accident
Preparedness, October 18-20, 1979, Oak Ridge.
At the Section II: Radiation Accidents: Acute Local Irradiation, there is a
article "Clinical Course and Dosimetry of Acute Hand Injuries to Industrial
Radiographers from Multicurie Sealed Gamma Sources, by Eugene L. Saenger,
James G. Kereiakes, Niel Wald and George E. Thomas. The table I, page 173,
gives the approximate Gamma-ray dose rates to the hand for 1 Curie in a
Sealed Source, considering the parameters that I was looking for, for the
following four sources, Co-60, Cs-137, Ir-192 and Ra-226.
NRPB Protection against radiation from brachytherapy sources, n. 40, march
1972

Dear colleagues I need to prepare an information, please, who can confirm
the below data:

Approximate dose rate to the hand for I Curie of Cs-137 (see note 1):
Surface Dose Rate 513 R/min, Dose Rate at 1 cm tissue depth 28 R/min,  Dose
Rate at 3 cm  tissue depth 3.7 R/min. For the purpose of calculations the
activity is considered to be a point source and Industrial source housing
are usually for stainless steel, outside diameter ¼ inch, with a wall of
1/32 inch thick,  source considered point source.

Accidents, Reference Manual REAC/TC, December 7/8, 1987, Rio de Janeiro,
Brazil.

Thanks for the help
