A sample will be placed in a small vacuum chamber_ facing a
gol_-silicon alpha-particle detector. The sample will be kept at
room temperature and at approximately a 1-micron pressure. Depending
on the level of activity_ a period from a few hours to a few days may
be required to complete the measurements.
A soil mechanics investigation to be conducted is restricted to
the soil remaining in the Surveyor III scoop. Objectives include
comparison of soil mechanical properties_ particle size_ and albedo
with measurements _de during actual Surveyor III operations on the
same material. These comparisons will aid in understanaing these
properties and in evaluating techniques used for remote measurements
in future unmanned space probes.
