This paper demonstrated a useful empirical Þt to
measurements of soil moisture during oven drying.
Room temperature measurements of the radon exhalation
rate as function of soil moisture content
combined with the empirical moisture Þts during
oven drying could predict the radon exhalation due
to a changing soil moisture content during oven
drying. Determinations of the radon exhalation
during oven drying would account for radon losses
in processed soil samples and would be useful in
situations where the immediate laboratory gammaray
spectroscopy of dried soil samples would not
allow radon and its decay progeny to build up to
their saturation levels.
