DO-RA Radiation Sensor

dora

DO-RA is a radiation gadget that will plug into the audio jack on a smartphone, tablet or laptop and, when used in conjunction with the DO-RA app, will be able to record radiation measurements — using a silicon-based ionizing radiation sensor — to build up a picture of radiation exposure for the mobile owner or at a particular location (if you’re using it with a less portable desktop device).

The system can continuously monitor background radiation levels, when the app is used in radiometer mode (which is presumably going to be the more battery-draining option — albeit the device contains its own battery), taking measurements every four seconds. There’s also a dosimeter mode, where the app measures “an equivalent exposure over the monitoring period” and then forecasts annual exposure based on that snapshot.
