This application is a real working radioactivity counter without any extra hardware needed ! It will turn your phone into a Geiger Müller Counter to measure radioactivity after proper calibration.
** Attention after upgrading iOS to a higher iOS do the calibrate again, as camera data properties might have changed **
Disclaimer: The type of radiation picked up by the camera can be dangerous/detrimental to the user's health as well as cause damage to the device.
Important note: The camera sensor can measure gamma radiation (CS137 for example) and some beta radiation (depends on the energy if the beta rays can pass through the plastic parts - for example H3 or K14 are weak sources). It cannot measure alpha rays (PO210) For AM241 though its primary a Alpha source also some gamma radiation is emitted and might be detectable for a longer measurement. Please check our homepages for examples and hints on how to measure.
We did calibrations with several iPod2, IPhone 3GS, iPhone 4, iPhone 4S, iPhone5, iPhone 5S and iPad 2, iPad 3 devices at the Helmholtz Research Centre, Munich. we used a CS137 test source from 10 µGy/h till 1 Sv/h for each of the phones we had. The values are stored for a rough start on the application (all devices differ a little bit). For precise professional measurement the devices must be adjusted to the sensor which is possible with the expert setup. For personal use the defaults should be sufficient (please give us feedback).
What's New in Version 1.3
iOS7 support, several compatibility problems were solved, so iOS7 can be used now.
iPhone 5S added to the predefined calibration tables.
More infos in the CSV file, new name scheme,
email default can be changed now.
I have this app on my iPhone 4 and 5s and it works great! I just downloaded it to my iPad Air but have yet to try it...will update. I had to look under iPhone apps only to download it to my iPad though.
