External Gamma Exposure
Monitors conducted a film badge program to give an account of
accumulated radiation doses off-site.
Three hundred and thirty
film badges were placed on individuals and structures within a one
hundred mile radius Of the. test site,

These doses measured by film badges have not been
corrected for natural background radiation exposure, which is ap-
proximately 0.5 mr/day.
Milk
Milk samples were collected from eight producer dairies in
the vicinity of the Gnome site.
Results indicate that no increase
of radioactivity was detected in the milk supplies from the Gnome
event.
Mine Surveys
DOE ARCHIVES
Eight mines located within a 30 mile radius from the Gnome
site were monitored for external beta-gamma levels before and after
the shot event.
The two sets of readings remained the same within
the tolerance of the instruments used.
