body burdens of Ce-187 of 88 pCi /kg which is tery pear the maximom permissifle burden of 43 pCi /kg. Memo Conard to Liverman, May 11, 1977.
October 1977 : Large volumes urine samples collected under controiled conditions

eS, sir.
r }aTes. Did you have non-Bikinians working for them at that
Mr. Dest Tcan’t answer that.sir.
rT. DEYOUNG. It is my understanding that there were other Marshallese in the work force who were not from Bikini.
Mr. Yares. You examined them es well. Were they examined
through that time?
Mr. prYornc. Yes, as long as they were on the island.
Mr. Yares. Go ahead.
{r Drar. We later included collections from the people who had
return
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. Deay. That is a very sophisticated counting system where you
essentially sit in a chair and where you have a counter that detects
radiation from ‘hz cesium that has been taken up in the body. It actuuly counts the body’s burden of cesium.
r. Yates. Is that the same strontium!
Mr_Drsi-Thes
travel together in the body. You can see that the
M
strontium is——
Mr. Yares. These are like the heavenly twins.
Mr. Dear_ You can measure the strontium with urine samples, but
we have not been able to see much of thet 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.
RESULTS OF THE 1975 RADIATION SURVEY
Peet Yates. Until ‘75 you found nothing. What did your tests
ow!
Mr Dray That is when we began to see the rise m the cesium. |
