and deposited under the dome contains a small fraction of the activity that has been in
Cactus Crater and nearby Lacrosse Crater for nore than 20 years and an even smaller

fraction of the activity known to be on the bottom of ‘the lagoon."
Members of the committee visited some of the atoll's islands in March 1980 to

examine the dome and observe the drilling program organized earlier by the committee to
provide information on the dome and its contents.

The committee also reviewed data and

reports on the DNA-directed cleanup and interviewed Key persons associated with the

The committee advised that while "no significant radioactive hazard would be
created if the containment structure were to fail in any way...dnspection of the dome
Should take place periodically and after severe storms."



The test drillings of the dome revealed that water flows freely between the
dome's contents and the ocean.

However, the connittee pointed out that most of the

radioactive elements which are fixed in concrete do not dissolve in water, and are
‘leached out of the dome very slowly, if at all.

An analysis of water and soil taken

fron the drill holes showed that the amount of radioactive elements was “far below the
“maximum permissible concentrations for the general public in drinking water" and
“comparable to soil sediment concentration in the northern part of the atoll."
