‘The details are not shown here but the
results are as follows:
For He703; y = 1.3022 - 0,0154t,
For Na@*:
y = 0.4336 - O,0014t,
Areas were computed from the equations for each day
that spectra were made and compared with the measured areas.
The average deviation for Nae was 0,03 in“

and for Hg
was 0.106 in’, The average percentage deviation was 2.0 per-—
cent for Ne@2 end 5.4 percent for Hge05,
The probable reason
for the higher deviation for Hg@°5 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.
