The fuel for the gas fired generator is supplied by two
5 gallon tanks of gasoline;
it was found
thac this
10 gallons
of fuel could provide the generator with power for approximately 16 hours.
Noce:
Check daily oil level; make sure
the oil is clean;
etc.
and that
the generator is not overheating,
(e)
The Hi Vol is equipped with an elaosed time meter to indicate the amount of time the sampler was run.
Note that
after each operation.
(£)
From preliminary data, it was found that continuous Hi Vol
sampling ac the indicated time for each island could provide
the necessary amount of Pu activizy in the filters.
Bikini--ac least 2.5 days tocal
Rongelap--at least 4 days total
If the filcers are only to be analyzed gravinecrically,
2.5 day samples act each island would be sufficienc.
HASL Sampler
(a)
Record che reading on the Drv cas Yeter. Also record the
“pressure gauge reading anc fill o.t¢ the information asked
for in the index card, e.g. dace, oil change, etc.
AFTER
REMOVING A USED FILTER AND UPON PLACING A NEW FILTER.
(b)
The filter to be used is microsorsan with a backing paper
between the filrer and the screen of the blower unic.
It
has a plastic frame to prevent adherence of the filter
Paper to the gasket.
Upon removal of a used filter,
care-
fully remove the plastic frame and fold the filter in half
then in quarter and place in a preweighed glassine envelope. Attach the index card with the necessary information and place in a plastic bag.
(c)
To verify optimum time for HASL sampling, the caretakers at
Rongelap, Bikini and Ucirik will have to be requested to
Note the pressure gauge reading once a week. This informa-
tion plus the requirements of minimum detection limits will
decide optimum sampling time.

Tentatively, HASL samples will be lefc ac the following
