INTERNAL DEPOSITION OF RADIONUCLIDES
appearipee of possible long term effects of
Spechnens were ohbtained from the lung, liver,
G. DT. tract and the skeleton, ‘The samples were
ashed at 440° Clin a anuffe oven, and the ash
made upto volume with 2N HCL An aliquot
was then dried for beta imeasurement. The beta
activity was determined by means of a thine
end-window Geiver-Muller counter. Sr" was
used as the basis for the mass absorption cor-
radiation.
A special study was carried out to determine
the effect of the radiation on the fertility of
chickens and the hatchability of their eas.
The animals collected from Rongelap and
Uririk ineluded 1) chickens, & baby chicks, 11
swine, 4 ducks and 1 eat. These were shipped
alive fo the USNRDL. Three fish and one
Jurge chum were taken from the Rongelap Ja-
rection for the samples, as it was the major
radiovlement deposited. ‘The correction calculated is an approximation. as mass abserption is a function of the averase energy of the
sample. Beta activity was measured in total
dan, and this vadne was converted to ge. "Sr

In
addition, a Luar, a cat and two chickens were
autopsied in the field. and representative tissues
were collected.

The ganna activity of the tissue samples was
measured ina well-type sodium iodide scintillavion caunter which has ‘an efficiency of about
40 percent for a Co” standard. The gamma.
