The corrections for mini-ionization chambers
used in this study (active volume between
0.015 cm
3
and 0.05 cm
3
) were generally lower
than
10%
and
for micro-chambers (active volume<0.015 cm
3
)
lower than
3%
.
active volume > 0.1 cm

corrections of 20%-30% !
These result confirm previous conclusions
that unshielded diodes a better choice of
detector than shielded diodes.
Small field detector correction factors
