measured areas. Thedetails are not shown here but the
rt
results are as follows::
For He203; y = 1.3022 - 0.0154t,
For Na@?;
y = 0.4336 - 0.0014t,
Areas were computed from the equations for each day
that spectra were made and compared with the measured areas.
for He@?3
The average deviation for Na? was 0,03 in 2 and

was 0.106 in’, The average percentage deviation was 2.0 per-—
cent for Ne®2 end 5.4 percent for Hg?05,
The probable reason
for the higher deviation for Hg295 is a combination of fewer
records, shorter half life (requiring progressively more
sensitive count-rate scales with consequent loss in statistical accuracy during the latter part of the recording
period) and higher amplifier gain requiring the use of more
sensitive count-rate scales to provide peaks of adequate
height.
