Apparatus for detecting ionizing radiation includes a mobile telephone, including an imaging assembly, which includes a solid-state image sensor. A radiation converter is mounted in proximity to the image sensor and is configured to emit, in response to the ionizing radiation, lower-energy radiation for detection by the image sensor. A processor, contained in the mobile telephone, is configured to process images captured by the image sensor so as to assess an intensity of the ionizing radiation. |
