SAMPLE .0.4 MBq of Cs-137 was used as a sample contained in 2273700100039
a 0.003 liters of Ca-Cl solution which was then 2273700100040
evaporated to dryness and deposited at the bottom 2273700100041
of the bottle as a thin disk 7 mm diam. and less than 2273700100042
0.5 mm thick. Accurate number of Cs-137 atoms was 2273700100043
determined relative to Cs-138 product atoms about 2273700100044
30 min after irradiation 2273700100045
.Monitor samples were 0.475% Co/Al and 0.061% Au/Al 2273700100046
alloys wires 0.76 and 0.51 mm diameter, 3 mm long 2273700100047
sticked on the outside of the sample bottle. 2273700100048
