The popularity of smartphones continues to grow with the availability of an ever-growing range of applications. The app, Radioactivity Counter, is designed to measure a person's exposure to radiation. It claims to accurately detect the dose in the radiation unit microGray per hour (μGy/h) using the phones in-built camera, which is not only sensitive to visible light, but to higher energy gamma photons.
