For those not familiar with particle detectors there is a great
display at the South Australian Museum<br>
<a class="moz-txt-link-freetext"

This display is a great example of the strange atomic world we live in
where not only materials and electrical devices are emanating
radioactive rays but they also rain down from the sky from space.
Invisible, most people are unaware they are present all round us and
even pass through us, buildings and some particles even pass
thought the earth as if it wasn't there. Under normal conditions these
particles are very diffused and random ranging in energy, time,
direction and type. <br>
<br>
There are an number ways a particle detector can be built not just a
cloud chamber <a class="moz-txt-link-freetext"

In
theory an array of simple detectors could be built to detect the
particles, direction and energy. This data could be captured and then
converted to
an audio or visual display that highlighting there presents also as the
incidents of particles is random would have the effect chaotic and
unpredictable<br>
<br>
With a little bit of googling I found a number of examples of cheap and
easy to build detectors.<br>
