Abstract
A radiation detection system may include a mobile device having a flash memory. The device may monitor various characteristics of the flash memory to determine when damage to the flash memory has occurred from radiation exposure. The device may associate damage to the flash memory with a radiation dose, and determine a level of radiation to which the memory, and thus the device, has been exposed. The device also may determine a length of time and locations where the radiation exposure has occurred. If the device determines that the level of radiation exposure exceeds a threshold associated with a safe level of radiation exposure for a human user, the device may generate an alert to the user.
