participation in
11th International Intercomparison of
Environmental Dosimeters 1996/97
- Environmental Measurements Laboratory (EML) of the US
Department of Energy (DOE), New York/ USA
in collaboration with
- Brookhaven National Laboratory (BNL), Upton, NY/ USA
- National Institute of Standards (NIST), Gaithersburg, MD,/
USA
- Idaho State University, Pocatello, ID/ USA
|
The organizers were positively surprised of the performance
with latest progress in electronic environmental dosimetry. Mrs.
Gladys Klemic *) agreed to be
at disposal for any further questions. |
|
|
GammaTRACER is in concordance with in the target values´
error at all tests. |
|
|
The deviation of the GammaTRACER relative to the Reuter
Stokes reference instrumentation is less than both instruments´
error bars. |
