FALLOUT DATA

4102:
I am enclosing a table of the gummed film fallout data, arranged by
station number and sampling day. I have previously sent you a list
of stations with their numbers. Tne sampling days are given as
calendar dates and also as days after December 31, 1953, in two rows
at the top of the table.
The numbers in the body of the table are d/m/sq. ft. extrapolated
to sampling day.
By “sampling day" we mean the day, Greenwich time,
when sampling began.
The sampling period is 2) hours and starts at
the sempling period.
In the case of samples collected on the day of
12:30 P.M. Greenwich time.
We have extrapolated to the middle of
a burst this midpoint occurs about 8 hours after burst.
Each "X" in the table represents a sample less active than approximately
800 d/m when counted.
We are giving you Xts instead of numbers for
these in order not to delay the information on the more active samples.
A blank space in the table indicates missing data,
filled in in a later report.
The data are for fixed stations.
