Smart Geiger instantly turns your smartphone into a Geiger counter

Smart Geiger is a portable Geiger counter that works by simply inserting it into your phone’s earphone jack. Readings can be seen on its pair app that’s compatible with iOS and Android devices.

Radioactive substances are measured in dose-rate figure (usv/h). The app emits a sound similar to commercial Geiger counters to let you determine the distance between the radioactive object and your phone. Measurements have an error percentage of 30% due to variations in the build and performance of smartphones. For more accurate readings, perform measurements several times over using different smartphones.

This add-on can be used to detect radioactivity in areas with a history of radiation leaks. It’s an inexpensive alternative to conventional counters that are costly and bulkier than this plugin.
