Dear Bill:

This letter delineates our objectives and our requests for PASO assistance
with respect to the R. V. Liktantir Voyage No. 7.
This letter also supercedes
that dated July 2 from Bob Miltenberger to Harry Brown.
The objectives of this field trip are as follows:

1.

Personnel monitoring (whole body counting and urine bioassay) at Rongelap
and Utirik as part of a regular surveillance program for these atolls.
Whole,
body counting (WBC) at Rongelap and Utirik was last done in April 1977, and
these atolls are again due for a personnel monitoring visit based on an
established schedule of once every 2 to 3 years.
During our stay at Rongelap,
a rebuilt wind-powered electrical generator will be installed to operate our

continuous air sampling equipment.

An additional 10 foot tower section will

be added to the wind-powered generator at Utirik in an attempt to remove it
from a turbulence zone which reduces its operating efficiency.
We also
expect to continue our environmental sampling and diet assessment programs
at both atolls.

2.

Personnel monitoring at Ujelang for the purpose of establishing baseline body
burdens of +3’cs, 3¥sr/90y, and other radionuclides.
We have established 14
categories of personnel monitoring subjects based on parameters which we
feel are relevant to internal dose assessments for the returning Enewetakese.
The categories are presented in the following table:
