IMPROVE use alloy foil piece below black tape to cover, and test with a flashlight. VERBESSERUNG: bitte Tabellen der Telefon-Kalibrierungen einpflegen (Analog der Umrechnungstabellen) sodass man unabhängig von der Homepage die Werte einpflegen kann. Erstaunliche App
Surprising ! I was not expecting the accuracy to be as good, but it closely compares to the readings from my GMC-320v4
Elegant and Powerful Surprisingly accurate when compared to a dedicated geiger counter. Excellent idea and very well executed.
Interesting idea, but doesn't work well It is very difficult to fully cover the camera. A black electric tape, for example, is not entirely opaque. The "counts" that you see are mostly optical photons that leak through the tape. To check, compare a measurement indoors to a measurement in direct sunlight - you end up getting > 10kcpm rates, easily.
It works great! But, it depends on your phone. I have an Optimus LG D-500. It's not rated well for My phone. It has a slow response on my phone. It only works well around a strong radioactive source, such as Cs-137, Sr-90, Ra-226, Am-241, or my X-Ray tube up close. It depends on the energies and activity of the source. This wouldn't work with C-14, H-3, Po-210, or Pu-239. Test it thoroughly, and use it until you get the best results.
More discrete than having a geiger counter in your everyday carry Yes this isn't an adjusted official tool. But it's better than nothing. As long as you have electricity when SHTF (solar, generator) to charge your phone, you have some sort of a clue what's up when your cellphone starts ticking. LG P880, Cyanogenmod Nightly
