AW: Mapping High Gamma Dose

[Gutermuth Frank <F.Gutermuth@gsi.de>]

Dear Dr. Abu-Jarad



You might try to use aqueous chemical dosimetry. I measured dose rates

(around 10 Gy / min) at Co-60 source using ferrous sulfate dosimetry (Fricke

dosimetry) with very good accuracy (3-5%). You need a photometer (UV around

300nm for ferrous sulfate) to do this. See for example "Radiation Dosimetry"

by Attix/Roesch Volume 2 Chapter 12 for an introduction to chemical

dosimetry.



Best regards

Frank Gutermuth
