Here you find some videos with examples made ourself or by customers, partners on the RadioactivityCounter App - Videos are in HD, so you first switch to 720p then to full screen for best results.:


Video review from BIONERD23 (thanks a lot), with comparision and helpful tips for setup from a nativ speaker (17min in length).


Video of a longtime timelapse measurement with mineral samples in the CloudChamber mode. Running our RadioactivityCounter App on the iPad 2. Thanks to Stefan Klemenc for providing the video.


Video of a longtime timelapse measurement with background radiation (showing cosmic particles) and a week source (TG-series Spark Gap Tube with Cs137 as ionizing source) and a Thorite for comparison.  Thanks to Stefan Klemenc making the video about this example. When you see long lines or larger dots these represent  radiation  from either the environment or cosmic particles (sun flares etc.). Single Pixel can be the result of a hit or a noise effect on the chip. Very large structures are typically of cosmic origin as the result in a cascade of electrons which hits the sensor when converted. Some research on Neutrons hitting videochips has been done already to be found in the Web and a dependance on the max line length an energy deposited.
