\begin{abstract}
A 10-year data set of alpha and gamma radiation from radon in air has
been collected using an Enhanced Confined Mode experiment (ECM; EXP
\#1). Analysis of periodic phenomena from annual to sub-daily scales of
the variation of nuclear radiation from radon reveals: a) Possible
multi-year variations; b) Periodic signals which occur in the annual,
solar rotation (around 30 days), and daily frequency bands; c)
Semi-annual and ternary-annual variations which occur as multiples of
the primary annual periodicity; d) Daily variation of 24-hour
periodicity which is accompanied by multiples of 12- and 8-hours; e)
Non-linear couplings among the annual, solar rotation and daily
periodicities; f) Evidence of directionality in the gamma radiation. The
setting of EXP \#1 is at an above surface outdoor location which is thus
subject to large environmental influences. However, the most significant
statistical features cannot be attributed to local environmental
influences, although there is some similarity in the time domain. The
patterns of fundamental geophysical periodicities on annual to daily
scales and their modulation by Earth's rotation around its axis, support
the suggestion of an non-terrestrial influence, essentially of solar
origin. Further investigations of radon decays in the geo-sphere will
allow formulation of new geophysical implications.%
