Project: EVA: Incline Study Preparation

Personnel: Tulika Raj

Incline test was conducted at 3 locations with three volunteer subjects
from the crew. The data was recorded based on the rubric discussed
earlier for the comfort of standing and bending at various
inclinations, on various soil types during EVA.

Soil Radiation study was also conducted in the vicinity of the Hab. The
Corer and the Radiation meter were tested for use during EVA.

Technical/Equipment Issues:
Incline Test: T-square, protractor, string
Radiation Test: Soil Corer and Radiation meter

Discussion / Questions :

Inclinations of 0º, 35º and 45º were included in the study. The soil
type varied from crumbly red dried clay soil and hard soil to loose
rocky soil. The easiest location thus far was at 0º inclination and
most difficult was at 45º inclination. Further testing will be
conducted at other inclinations during future EVA.

The radiation study is a lot more difficult in application than in
theory, as the application of the Arctic section was carried out by
other people with a much better understanding of geology. Today was
very truncated, as the site Emily selected turned out to have rock about
an inch under the surface. Radiation measurements were taken at surface
level, showing an approximate reading of 1940 cpm. Translation from cpm
into dpm will have to wait until she has a better idea of the source of
the radiation, energy spectrum, etc. Questions have been sent to some
of the people who were actually doing the coring for the first part of
the study to provide guidance (apart from finding not-rock areas).
