A BROAD RANGE CHEMICAL DOSIMETER FOR GAMMA RADIATION.
N. Klein, April 1961.
UNCLASSIFIED
(uv)
This report describes the use of an air-saturated, aqueous
benzene system as a simple chemical dosimeter that measures gamma dose
in the tactical range and higher with accuracy and precision, The
system described is a laboratory technique that may have field application.
It is not currently suitable for consideration as a tactical
dosimeter.
However, this rather simple system is capable of measuring
dose in the range 20 r to 35,000 r.

NEUTRON FLUX MAPPING FOR THE KUKLA FACILITY (U).
J. H. McNeilly and J. W. Kinch, September 1961.
UNCLASSIFIED
(uv)
Neutron dosimetry measurements were conducted by this Laboratory
at the KUKLA Facility of the Lawrence Radiation Laboratories, Livermore,
California, during the period April 5 - 11, 1961.
The measurements were
made to supply input data for the Boeing Airplane Company's study of
the effects of radiation on electrical components.

Tne threshold detector system was used in making the measure-
ments which included (1) neutron flux versus distance from the source,
and (2) perturbation of the neutron flux caused by the electrical
components exposed in the radiation field.
The flux shows a slight
deviation from a 1/Ré dependence at distances of less than 25 cm.
There
is little, if any, perturbation of the flux field due to the insertion
of various electrical compgnents.

THE EFFECTS OF BORON-10 SHIELDS ON THE CALIBRATION OF
NEUTRON THRESHOLD DETECTORS (u).
J. H. McNeilly and J. W. Kinch, September 1961.
UNCLASSIFIED
(v)
This report describes the results of an experiment designed
to study the effect of boron-10 shields on the neutron flux and spectrum
i
as measured ty threshold detectors. The results include comparison of
data obtained from threshold detectors exposed to a neutron field in the
. following environments:
in steel spheres whose periphery is filled with
boron-10, in pressed and sintered boron-10 spheres, in cadmium capsules,
and unshielded.
