In what seems to be a response to public fears about radiation levels
following the Fukushima crisis, a Japanese organization called Radiation
Watch has launched Pocket Geiger, a Geiger counter iPhone peripheral and
accompanying app aimed at concerned individuals.

New Scientist reports that the peripheral has eight photodiode sensors to
detect radiation and aluminum foil to screen alpha and beta particles.
Second generation peripherals, known as Pokega Type2, do away with the need
for batteries, using the connected iPhone as a power supply.

The app functions as the Geiger counter display, but also uploads data to a
Radiation Watch server where readings are collectively mapped for an
overview. Apparently there are over 10,000 users, though the viewing of
maps is limited to Radiation Watch members.

The main advantage of the Pocket Geiger appears to be cost. Where a typical
personal Geiger counter would cost well into three figures, the peripheral
and app cost a mere US$46 - or $65 for the Pokega Type2.

Of course, the WikiSensor
looked at last October did away with the peripheral entirely.
