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 app we looked at last October did away with the peripheral entirely.

Is this picture for real? My IPhone doesn't have a connector where this appears to be connected.

Picture is SNAFU, but it's "real" - uses the headphone jack. They send full-volume audio which is uses by the device to power itself, and the microphone returns the data readings to their app.

The phone is just turned 180 degrees. Maybe you should take your phone back.

Foxy1968, take a closer look. the phone is right side up, with the button at the bottom. It is not simply turned 180. The picture must be a fake of some sort. I would like to see the device really hooked up to an iPhone.

I try to do a similar project, but the mold for the housing is pretty expensive so i had started a fund campaign on indiegogo, and if i am little bit lucky getting the cash for to make the housing, than the Geiger i am offering will not cost more than 99 usd. including free shipping around the world. The app is FREE, it's a very popular app, called Geiger Bot

The difference to the pocket Geiger above, mine is using a very popular Geiger Mueller Tube (SBM20), and the pocket Geiger uses just PIM diodes.

Does anyone know where to order either the first or second gen? The app is readily available, but I have yet to find the peripheral.
