Behandeld door drs. F.P. Otten
Project code : FOTTEN 11086625
Project omschrijving : HANGAR 8 SCHIPHOL
Bemonsteringsdatum : 03/08/1998
Monstercode : TOTAAL URANIUM
Referentienummer : 3280155
URANIUM mg/kg : 13,1
Opmerking : verhouding tussen U235 en U238 bedraagt 0,0024
"De verhouding tussen U235 en U238 is vastgesteld op 0,0024,hetgeen duidelijk
lager is dan de natuurlijke verhouding van circa 0,0072. Dit wijst op
uraan dat verarmd is ten opzichte van natuurlijk uraan".
