Cesium~137 in the Jan. 1955 sample was determined by a
standard chemical method; cesium-i37 in the Oct. 1955 and July
i956 samples by analysis of gamma spectra of the dried filtrate
from 5r(NO3)q precipitation, and cesium-137 in the remaining
samples by analysis of gamma spectra of iried unashed sample.
