Whilst this iPhone radiation meter is not something an average person will need, the Fukushima crisis has worsened and our attention has been constantly drawn to the hazardous effects of radiation exposure and its danger to the environment. Primarily designed for the Japanese market, the DO-RA uni model is an easy tool for those interested in day-to-day radiation exposure. The DO-RA uni model with a silicon- (Si) based ionizing radiation sensor is alike to a Geiger-Müller tube (or GM tube) and will have cross platform compatibility. The meter connects through your devices audio jack and when used with the DO-RA app it ‘records radiation measurements [...] to build up a picture of radiation exposure for the mobile owner or at a particular location’ for less portable devices. The device will retail at around US$150
