A semiquantitative analysis of a Messerschmidia sample
collected in 1956 at Wotho Atoll was made in a single-channel,
50-position,
automatic advance gamma spectrometer with a two-
inch well-type sodium iodide crystal.
Por some of the 1958 samples the amount of sr9° was
determined by the precipitation plus ion-exchange method of
Kawabata and Held
(1958).
Radioactive beta decay data were obtained for some of
the 1956 samples.
The
and
common names of the organisms are used in the text
tables.
The scientific
names are
given in Appendix

The individual gross beta values plus or minus the 95
per cent counting error from ten collection sites during the
interval
1954 to 1958
are given
in
Appendix Tables A to K.
A value identified as background signifies that the counting
error
was as great or greater
than the net count,
count after background was subtracted.
