Human beings are exposed to ionizing radiation from human-made and natural sources (terrestrial, cosmic, and internal radiation). It can also be used for personal dose assessments and as an alarm for the presence of high radiation levels. Although the smartphone is not as accurate as a conventional detector, it is useful enough to detect radiation before the radiation reaches hazardous levels. The precision of the measurement is also affected by heat and a smartphone’s battery level. The Radioactivit圜ounter app is limited in that it requires 4–10 min to offer a stable measurement. The smartphone CMOS sensor is sensitive to radiation doses as low as 10 µGy/h, with a linear dose response and an angular dependence. The Radioactivity counter app developed by Rolf-Dieter Klein and available on Apple’s App Store was installed on the device and tested using a calibrated radioactive source, calibration concrete pads with a range of known concentrations of radioactive elements, and in direct sunlight. Black tape was utilized to block visible light.

This work aims to report a detailed investigation of a well-reviewed smartphone application for radiation dosimetry that is available for popular smartphone devices under a calibration protocol that is typically used for the commercial calibration of radiation detectors. Radiation incidents on a smartphone camera’s Complementary Metal Oxide Semiconductor (CMOS) sensor creates a signal which can be isolated from a visible light signal to turn the smartphone into a radiation detector. The advanced image sensors installed on now-ubiquitous smartphones can be used to detect ionising radiation in addition to visible light.
