These areas were covered with soil during that year;
a radiological
survey in March 1950 showed less than 0.001 R/hr on Enjebi and Aomon and
an average of 0.002 R/hr on Elereron.
On Runit the general radioactivity
was 0.0015 R/hr, but some of the old shot tower footings showed 0.012 R/hr.
After a third survey in April and May of that year,
it was concluded that
no possibility of overexposure to gamma radiation existed on any island of
the atoll and the wearing of film badges was discontinued

Shot GEORGE of GREENHOUSE left a large radioactive crater on Eleleron.

during Operation IVY, destroyed the island and left an underwater crater.
