Abstract:

Surveying ionizing radiations of the surrounding with a smartphone provides a low-cost and convenient utility for the general public. We developed a smartphone
application (App) that uses the built-in camera with a CMOS sensor and a radiation signal extraction algorithm. After a calibration through a series of radiation exposures, the App could display radiation dose rate and cumulative dose in real time without requiring covering the camera lens. A smartphone with this App can be used as a fast survey tool for ionizing radiations.
