Calibration of Indirect reading Pocket Ion Chambers

[Thomas Johnston <tjohnsto@admin4.hsc.uth.tmc.edu>]

Hello Radsafers-
    I am looking for information/guidelines/procedures for the response 
check/drift tolerance, etc. of Victoreen pocket ion chambers, indirect 
reading type, Victoreen #362.  I am looking for someone that has possibly 
been through this already and can provide me with some assistance or 
guidance. These dosimeters are read in a Victoreen Minometer II.  I would 
appreciate responses from anyone that has relevant experience with these 
dosimeters.  I know that there are several NEW products out there that 
could do the job of exposure monitoring.  However, we are using what we 
have to work with.  These dosimeters are used at our Cyclotron facility 
for monitoring daily personnel exposures and are NOT used for permanent 
dose records.
   I am also interested in alternatives to these dosimeters, i.e. does 
anyone have an alternative to this type of dosimeter for monitoring daily 
personnel exposures.  We will consider purchasing new equipment, but only 
if all else fails, and there aren't any alternatives.
