Mr
Dear We made resurveys of the Bikini environment, including
soi] and
groundwaters in 196%, 1970 and 1972. Annual collection of
urine samples for radiation analysis began in 1970, and with those peo-
ple who were working for the agricultural and housing projects.
Mr. Yates. Ars these only Bikinians?
Drat.
Yes, sir.
; Mr Yates. Did you have non-Bikinians working for them at that
we
time
Mr. Dear I can’t answer that, sir.
tT. Dp YocNG. It is my understanding that there were other Marshallese in the work force who were not from Bikini.
Mr. Yates. You examined them as well. Were ther examined
throughthat time?
Mr. prYouns. Yes. as Jong as they were on the island.
Mr. Yates. Go ahead.
pr. Dra. We Jater included collections from the people who had
returned
living in the houses: monitoring the Bikini residents was
done by whole body counts in 1974 and 1977.
Mr. Yares. What is a whole body count?
Mr. DeaL. That is a very sophisticated counting system where you
essentially sit in a chair and where you bave a counter that detects
radiation from the cesiumthat has been taken up in the body. It actually counts the body's burden of cesium.
Mr. Yates. Is that the same strontium?
Mr. Drap_They travel together in the body. You can see that the
strontium is——
Mr. Yates. These are like the heavenly twins.
Mr. Draz_You can measure the strontium with urine samples. but
wehareé nor been able to see much of that in the urine samples avail-
able to date. They do the whole body counting sample for cesium.
We had a major resurvey of Bikini and Eneu Islands in 1975.

Mr. Yates. Until ‘75 you found nothing. What did your tests
;
show ?
Mr. Deap. That is when we began to see the rise in the cesium. —
